I got one problem while doing one TAPI application based project in C#. I'm using ITAPI3.dll
My problem is.. i'm not getting incoming call information. To get the incoming call information, i'm using the get_callinfo function, but it is showing empty message.
Did you try a different modem?
TAPI is very hardware dependent
This might be a useful MSDN starting point:

I'm just experiencing the same problem. When i debug, a openfiledialog opens asking me to open a file. i'm no sure what it is right now, will get back when i find something. So i just skips the line of code, what causes it to be empty.
I found what was causing the problem for me :
get_callInfo has 3 constructors : one returning object, one returning int and one returning string. For some reason, the one returning object is failing. So i tried the string constructor. This gave me all the information i need. I'll give an overview of all attributes you can choose from :
e.Call.get_CallInfo(CALLINFO_STRING.CIS_CALLEDIDNUMBER);
e.Call.get_CallInfo(CALLINFO_STRING.CIS_CALLEDIDNAME);
e.Call.get_CallInfo(CALLINFO_STRING.CIS_CALLEDPARTYFRIENDLYNAME);
e.Call.get_CallInfo(CALLINFO_STRING.CIS_CALLERIDNAME);
e.Call.get_CallInfo(CALLINFO_STRING.CIS_CALLERIDNUMBER);
e.Call.get_CallInfo(CALLINFO_STRING.CIS_CALLINGPARTYID);
e.Call.get_CallInfo(CALLINFO_STRING.CIS_COMMENT);
e.Call.get_CallInfo(CALLINFO_STRING.CIS_CONNECTEDIDNAME);
e.Call.get_CallInfo(CALLINFO_STRING.CIS_CONNECTEDIDNUMBER);
e.Call.get_CallInfo(CALLINFO_STRING.CIS_DISPLAYABLEADDRESS);
e.Call.get_CallInfo(CALLINFO_STRING.CIS_REDIRECTINGIDNAME);
e.Call.get_CallInfo(CALLINFO_STRING.CIS_REDIRECTINGIDNUMBER);
e.Call.get_CallInfo(CALLINFO_STRING.CIS_REDIRECTIONIDNAME);
e.Call.get_CallInfo(CALLINFO_STRING.CIS_REDIRECTIONIDNUMBER);
hope this still helps

This is my first question here so please go easy on me. :)
I'm also new to Blazor but not c#.
I am building a Blazor server-side application where a user can enter some information and check if it's valid or not based on some data on the server.
So far I have no issues with calling the function of the class that does the lookup and returns a record to display on the browser.
My problem comes when I want to display that information.
In the c# code, I have a variable called SdItem which contains the record that comes back from the query.
To display the data on the razor page I use the following lines.
#if (SdItem != null)
{
<div>
Code: #SdItem.Code<br />
Desc.: #SdItem.Desc<br />
</div>
}
When SdItem gets the data it obviously does not display the information until I call StateHasChanged();
This of course throws an exception so I had to change it to await InvokeAsync(StateHasChanged);
Although after this change the information shows on the screen and all seems to be fine, I came across a new issue which I could not find a solution or an explanation anywhere on the internet.
During debugging, MS Edge automatically starts and displays the website.
To test this strange issue I also start Firefox to point to the same local address.
Then I use my smartphone as well and that is where I start the query.
When I get the results back, not only do they show up on the phone but on all active browsers that are currently displaying the site.
Why does this happen and how can I stop it.
At the moment I managed to stop this from happening with an ugly code
try { StateHasChanged(); } catch { }
This suppresses the exception and the result is only being displayed on the browser that does the request. This is ugly and I don't like to use it.
Any help would be appreciated.
Just as information, in case this could be the reason. The queried data is in a List in a class which is added as a scoped service. But T is a private variable in the code on the razor file.
"When SdItem gets the data it obviously does not display the information until I call StateHasChanged" Why is this obvious? I would expect Blazor to update the display whenever displayed data is changed. You should very rarely need to call StateHasChanged. This makes me wonder what else is going on.
First thought that springs to mind is that SdItem should be a property...
public Whatever SdItem { get; set; }
...and not a private field...
private Whatever SdItem;
I'm not sure if needs to be public, but when using properties, Blazor (almost) always updates the display. When using private fields, if often doesn't.
"This of course throws an exception" Again, I don't see why this is so obvious that you say "of course." It all depends on where you are calling StateHasChanged. Yes, if you're inside an async block then you'll need to call InvokeAsync, but if you arent, then you shouldn't need to do that.
More code would be useful, as its hard to know exactly what you're doing from the small snippet you provided, but try using a property (if you aren't already), and see if that avoids the need to call StateHasChanged.
If not, please update your question with more information.
I am attempting to use Specflow to automate web tests using Selenium. So far, things are going mostly fine, but I am now running into a problem. One of my steps allow for a user to input a variable, the step looks like this:
Given I click the (VARIABLE) Menu
And the code behind it is fairly simple, just clicking on a link based on the text that is passed:
driver.FindElement(By.XPath("Xpath to get to the variable")).Click();
However, there is a later step that must use this information. That is fine, you can use "ScenarioContext.Current.Add(string, variable)" and I know about that and have been using it. It functions for the needs that I was first informed of.
My problem is that now the business wants to be able to add multiple items at the same time. This presents two problems. Attempting to just call the step a second time throws an exception: "An item with the same key has already been added." and if I put this into a Scenario Outline, which would allow me to call the variable a second time in a second run, I cannot use the first variable in the final step.
Logically, this means that passing in a variable multiple times is the problem (which makes sense, given it's passing in as a string) and so passing the variable in as an array seems the logical way to go. The idea is that when I pass the parameter from one step to another as an array instead of as a string I theoretically won't run into this error and then I will be able to iterate through the items in the array in that later step with a for loop. This seems like something that SpecFlow should be able to do, but I am having issues finding out just how to achieve this. Does anyone have an idea on how to do this? I attempted to merely use:
Scenario.Context.Current.Add(string, variable).ToArray();
However, that does not work, and all of the examples of "ToArray" I can find in the SpecFlow documentation doesn't seem to be actually changing the variables you pass from one step to another into an array, it seems to be used solely inside of individual steps and never passed between steps. Is passing parameters using ScenarioContext.Current.Add(string, variable) as an array possible in SpecFlow?
Thanks in advance.
the simplest solution to your problem is to add an array (or list) to the context in the first step and then to get it out and add to it and then replace it again in future steps:
List<string> list = new List<String>();
list.Add(variable)
ScenarioContext.Current.Add(name, list);
then later
List<String> currentList = (List<String>) ScenarioContext.Current[string];
currentList.Add(variable);
ScenarioContext.Current[name]=list;
However I feel duty bound to point out some issues with your current solution. You should investigate the PageObject pattern and hide your element selection XPath inside your page objects. Imagine the business decides to change the element that information is stored in. Now you have to change every test that does this:
driver.FindElement(By.XPath("Xpath to get to the variable")).Click();
for that variable. Using the page object pattern this is hidden inside the page object and you would only have a single place to change.
I personally would also consider sharing data using context injection as I find this allows strong typing of the data (so no cast is required like in the example above) and it allows you to know what data is stored, its not just a random bag of stuff).
I am experiencing a problem with loading of my work order page.
When I load my page I am just passing the id of the work order WO.aspx?inspectionid=12345
Now on computer 1 I am loading
WO.aspx?inspectionid=1
Now on computer 2 I am loading
WO.aspx?inspectionid=2
To reproduce my issue I click the respective inspection on each separate computer at the exact same time (well as close as I can to a manual simultaneous click)
Now when I debug my LoadWorkOrder function in my code, it calls a stored procedure and populates a Dataset. Now before the first call completes and loads up the rest of the page, I see that my second call is already hitting my LoadWorkOrder function, thus causing one of the pages to error out.
So my question is, is there a way to properly handle multiple calls on the same function. Is this a threading related issue? I am not quite sure even what to google to help solve my issue.
private void LoadWorkOrder()
{
//Bizlogic.cInspectionsBizLogic.GetInspection(dstInspection, mintInspectionID);
dstInspection = new cInspectionsDST();
Bizlogic.cInspectionsBizLogic.GetInspection(ref objDataAdapterForUpdate, dstInspection, mintInspectionID);
if (dstInspection != null && dstInspection.Tables[0].Rows.Count > 0)
{
Bizlogic.cSchedulerDST dstItem = new cSchedulerDST();
dstItem = Bizlogic.cSchedulerBizLogic.GetScheduleItemForInspectionID(mintInspectionID);
LoadInspectionAddressHeader();
I don't see anything special here, its just a simple loading of a dataset. The error message I do seem to be getting "There is no row at position 0". Within my cInspectionsDST.Designer.cs file. These DataSets are created within Visual Studio I've inherited so changing those is unfortunately not an option.
dstInspection was a static variable once I removed that and reworked the code I no longer had this issue
Sorry i am new to C#. I have a program, where there is a class CatchFS. The main function in the class , has the code
CatchFS fs = new CatchFS(args);
fs.Start();
Can someone tell me what it means. I hv heard of thread.start() but object.start() is new to me . Am i even thinking right ?
Thanks a lot, Yes it is derived from a class called FileSysetm.cs. The start does this : public void Start ()
{
Console.WriteLine("start");
Create ();
if (MultiThreaded) {
mfh_fuse_loop_mt (fusep);
}
else {
mfh_fuse_loop (fusep);
}
}
Now im trying to do a fusemount. The program starts and it hangs. there is some call that was not returned and i couldnt figure out which one. I tried using debug option of monodevelop, but no use, it runs only in my main function and I get thread started and thats it !!
I think the file FileSystem.cs is from library Mono.fuse.dll. Thanks for all your time. I hv been looking at this question for 2 whole days, and I dont seem to figureout much as to why the code wont proceed.Im expecting my azure cloud storage to be mounted in this fusemount point. My aim is after running this code I should be able to do an ls on the mountpoint to get list of contents of the cloud storage. I am also suspecting the mountpoint. Thanks a lot for providing me all your inputs.
There is no object.Start method. Start must be a method of the CatchFS class or some base class from which CatchFS derives.
If possible, consult the documentation for the library CatchFS comes from. That should hopefully explain what CatchFS.Start does.
If the documentation is sparse or nonexistent but you do have the source code, you can also simply take a look at the CatchFS.Start method yourself and try to figure out what its intended behavior is.
If there's no documentation and you have no source code, you're dealing with a black box. If you can contact the developer who wrote CatchFS, ask him/her what Start does.
One final option would be to download .NET Reflector and use that to disassemble the compiled assembly from which CatchFS is loaded. Treat this as a last resort, as code revealed by Reflector is typically less readable than the original source.
Start is a method on the CatchFS class (or one of its parent classes) - you'll have to read the documentation or source for that class to find out what it actually means.
According to the MSDN Docs for Object, there is no Start method. This must either be a method of CatchFS or one of it's base classes.
I am getting the following error:
Error 49 No overload for method 'getData' takes '1' arguments
With this method on the 5th line.
[WebMethod]
public string getVerzekerde(int bsn)
{
ZDFKoppeling koppeling = new ZDFKoppeling();
return koppeling.getData(bsn);
}
The getData method looks like this:
public string getData(int bsn)
{
using (new SessionScope())
{
ZorgVerzekerde verzekerde = PolisModule.GetVerzekerde(bsn);
return "Verzekerde " + verzekerde.Naam;
}
}
I realy don't understand what is going wrong here.. The description of this error on the msdn site didn't help me.. http://msdn.microsoft.com/en-us/library/d9s6x486%28VS.80%29.aspx
Someone who has a solution?
Yeah; somehow you're compiling against a different version of that class. Do a clean build, and double check your references.
Put an error in the GetData() method, then do a full build and confirm that the compiler find the errors. You may be editing the wrong file if you have more then one copy of the source code on your machine, and this will show you if you are.
Also try renaming the ZDFKoppeling class without updating getVerzekerde() and check you get a compiler error. If not you are not picking up the changed class for some reason.
If the above does not give a compiler error, try a rebook, as a process my have the dll locked, and also try a complete rebuild.
These problems normally turn out to be very simple once you have tracked them down. But get take forever to track down.
If another programmer works in the same office, ask for his/her help, as often a 2nd set of eye on the machine can find it quickly.
(I am assuming that GetData() is defined in the ZDFKoppeling class, not some other calss)
This generally indicates that it's not referencing the method you thought it was, but instead a different one. You can generally find out what method that is in Visual Studio by right clicking the method call and selecting "Go to definition". This should help work out why it's calling the one it is and not the one you expect.
Where is the getData method defined? Is it in another assembly? Have you tried rebuilding?
It doesn't look like anything's wrong with your the code.
