WinForms Map location coordinates

when the form loads user needs to enter street and city. After that I need to show him that location on the map and also to save longitude and latitude of that address.
I've done only this, which finds the location of the street and I can display it on the form(but it's ugly,if you have better solution please share). But I don't know how to get coordinates of that location.
StringBuilder queryAddress = new StringBuilder();
queryAddress.Append("http://maps.google.com/maps?q=");
queryAddress.Append(street + "," + "+");
queryAddress.Append(city);
webBrowser1.Navigate(queryAddress.ToString());

What you're looking for is known as Geocoding, getting coordinates based on address.
Google has a Geocoding API, which has a really nice documentation here.
I recommend you to read it thoroughly, and I will summarize the crux of the approach:
You can use Google's Geocoding API over HTTP(S) like this:
http://maps.googleapis.com/maps/api/geocode/outputFormat?parameters
where output is json/xml and paramaters can vary, but the simples form is address like in your example above and a mandatory Google's API key.
Example:
https://maps.googleapis.com/maps/api/geocode/json?address=1600+Amphitheatre+Parkway,+Mountain+View,+CA&key=YOUR_API_KEY

Calling NvAPI_GPU_SetEDID on Nvidia card

How do you call this method on Nvidia GPU:
NVAPI_INTERFACE NvAPI_GPU_SetEDID (
NvPhysicalGpuHandle hPhysicalGpu,
NvU32 displayOutputId,
NV_EDID * pEDID
)
Src: http://docs.nvidia.com/gameworks/content/gameworkslibrary/coresdk/nvapi/group__gpu.html#ga6a41b31dd9743120213435d985f8fbcf
I need to execute the above command to remove all EDID set on all DisplayOutputs on our new Quadro Graphics Cards. Based on the API documentation, I tried searching for NvPhysicalGpuHandle and came across this project/library:
https://github.com/openhardwaremonitor/openhardwaremonitor/blob/master/Hardware/Nvidia/NVAPI.cs
This does not have the method I need NvAPI_GPU_SetEDID
I am not hardware programmer, I just need to be able to call this one command. any ideas? Can this be achieved using nvapi.dll/nvapi64.dll via pinvoke or something?

I personally didn't test this, but you can try the library and see if it can set EDID information without any problem, if it fails, please open an issue.
https://github.com/falahati/NvAPIWrapper
Here is how you should do it,
First, you need to find the right DisplayDevice or GPUOutput that you want to write EDID information to. There are multiple ways to do so.
Get a list of all PhysicalGPUs in the system using the NvAPIWrapper.GPU.PhysicalGPU.GetPhysicalGPUs() static method, then select the PhysicalGPU you desire based on your logic. After finding the right PhysicalGPU, use the NvAPIWrapper.GPU.PhysicalGPU.GetDisplayDevices() method to get a list of all connected DisplayDevices to that GPU and store the right one in a variable.
Instead of searching for connected DisplayDevices, you can also go for the GPUOutputs. Just like before, you first need to find the right PhysicalGPU and then you can get a list of all GPUOutputs using the NvAPIWrapper.GPU.PhysicalGPU.ActiveOutputs property and store the right GPUOutput in a variable.
Another way to find the right DisplayDevice is to go for a list of all Displays. To do so, you need to use the NvAPIWrapper.Display.Display.GetDisplays() static method. This returns an array of Displays. Then using the NvAPIWrapper.Display.Display.DisplayDevice property, you can get the corresponding DisplayDevice of a Display.
After finding the right DisplayDevice or GPUOutput, you should use the NvAPIWrapper.GPU.PhysicalGPU.WriteEDIDData() method. This method allows you to write EDID data stored in a byte array to the DisplayDevice or the GPUOutput you selected before.
Note: Make sure to capture NVIDIAApiException and check for the NVIDIAApiException.Status property in case something went wrong.

save Website Content & access it

I'm starting with C# again after 3 years (have average experience with object orientated languages; here I'm mainly missing function names). I'm not too sure it's possible in c#, so if you can recommend another language I will try to look there.
My Question(s):
On program start (or button) I want to extract a part of a Website and save it (temporary of file don't matter). That way I wont need to buffer/load (loadtime) anything again and can access the content if I go offline afterward.
I want to extract some numbers out of the content and do simple math with them.
Would be great to know if its possible and how. I'm happy if you can tell me the main functions I should look into. Some basic code would be great too if its not too much to ask.

If you want to have access to the information even if your program closes/restarts then you will need to export the source code to a file as follows:
using (WebClient wb = new WebClient())
{
string source = wb.DownloadString("http://example.com");
File.WriteAllText("c:\\exampleFile.txt", source);
}
Otherwise you can remove the File.WriteAllText("c:\\exampleFile.txt", source); and simply parse the parts you want from the source and do your calculations.
Keep in mind this will download the source code of the url as 'it is' that means you will need to do some parsing of the text in order to get the information you want out of it.

May be you are looking for this:
var contents = new System.Net.WebClient().DownloadString(url);

Search by country and keyword/term?

I have recently started using google places api and am a big noob on it, I have looked around the main docs on how to run a query on the API but seems that It does not support what I want or im looking at the wrong place.
I need to search on a specific place for a specific term for example:
Restaurants and USA
Is this possible or how would I have to go in order to produce it using the API ?

When you do a Places Search: https://developers.google.com/maps/documentation/places/#PlaceSearches
You can specify a types parameter which limits the types of things you are searching for.
Or you can specify a keyword parameter which selects for a certain term across the whole Place record.
For location, your only option is to select a latitude/longitude pair and specify a radius. This won't work for "USA" as the maximum radius is 50000 meters. You could add that as a keyword however. For locations such as cities, you could geocode first to get the lat/long pair:

handling pixels in xsl fo

I have a Web front end and I am trying to handle layout with tables, because my tables all contain a col with a width- in pixels, what is the best way to handle it inside the pdf to get a consistent layout...?
I am using fo.net and the code I use to convert pixels to in is: However on different machines I am getting inconsistent results...
<xsl:value-of disable-output-escaping="yes" select="floor(#width div 72)"/>
<xsl:text>in</xsl:text>
Is there a way using c# to get the screen resolution and any other info to get a more accurate result?

To answer my own question... use % with a fixed max width on the table, that way I can get the Xsl to work out the % of each column based on the total width of a table. This workaround seems like the best and most felxible way to handle my situation, the biggest problem is, pixels cannot be translated into xsl fo - if a person is working on a page then moves onto a different machine the outputted pdf could be drastically different.
On the note: I would like for mm to be supported alongside pixels in WYSIWYG editors... as I am using jquery client side I will most likely enhance my tables therefore requiring me to create this plugin. I hope this info helps anyone else who wants to create pdfs from client side WYSIWYG editors, I am sure this info can be applicable for other scenarios too... :)

In the class 'System.Windows.Forms.Screen' there are several functions and values concerning the screen.
