This is my code (.Net 4):
string dName = textBox1.Text + ".db";
string fExist = #"C:\word_app\" + dName;
if (!File.Exists(fExist))
{
MessageBox.Show("file doesnt exist");
}
Even if I have the file in that location , this messagebox will appear.
you have just to correct your path (its words not word)
string dName = textBox1.Text + ".db";
string fExist = #"C:\words_app\" + dName;
if (!File.Exists(fExist))
{
MessageBox.Show("file doesnt exist");
}

Here is my code
RegistryKey = regsohr;
regsohr = Registry.LocalMachine.OpenSubKey(#"HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Schedule\TaskCache\Tasks\{DFDC1B83-7FD3-4C77-8CD1-7391D1680ACA}");
sw.WriteLine(regsohr.GetValue("Path"));
It can't get into {DFDC1B83-7FD3-4C77-8CD1-7391D1680ACA}.
But when I delete that line everything works fine.
Anyone has any ideas why it can't open this SubKey?
I will appreciate any help.
My bad.
I have messed up with "HKEY_LOCAL_MACHINE".
regsohr = Registry.LocalMachine.OpenSubKey(#"HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Schedule\TaskCache\Tasks\{DFDC1B83-7FD3-4C77-8CD1-7391D1680ACA}");
Fixed it
regsohr = Registry.LocalMachine.OpenSubKey(#"SOFTWARE\Microsoft\Windows NT\CurrentVersion\Schedule\TaskCache\Tasks\{DFDC1B83-7FD3-4C77-8CD1-7391D1680ACA}");
Try this , for example i put it in a Label to check if it works
{
string readValue;
readValue = My.Computer.Registry.GetValue
(#"HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Schedule\TaskCache", "Tasks",Nothing);
Label6.Text = readValue;
}

public string ReplaceTest(int i)
{
string rep = this.textBox3.Text;
string reped = rep.Replace("sir, this.textBox3.Text");
}
Like this? this is what i want to do but another error comes up not all code paths return a value
string.Replace() takes two arguments:
the string to replace
the string to use instead
If you want to remove "sir", it means to replace it with an empty string:
string reped = rep.Replace("sir", string.Empty);

I want to write
Label "BuildingData" does not exist.
I know how to write using String.format and stringbuilder. I want to write this using String.Concat.
When I write code
String.Concat("Label ","\"","BuildingData","\"", "does not exist.")
The output is
Label \"BuildingData\" does not exist.
Add a space before does and you'll get the correct output. The quotes are a red herring - you're looking in the debugger.
using System;
public class Test
{
public static void Main()
{
var concat = String.Concat("Label ","\"","BuildingData","\"", " does not exist.");
Console.WriteLine(concat);
}
}
Here's the output.

My code
string userid;
string userimageid;
bitmap.save(#"C:\temper\temp\"+userid+"\"+userimageid+".jpg");
get build error! why can´t I create subfolder with string value name and insert image? still cant insert to that crated folder as name userid.
Yes, you can. But you must create first the folder and then save the bitmap:
string folderName = #"C:\temper\temp\"+userid;
if (!Directory.Exists(folderName) {
Directory.CreateDirectory(folderName);
}
bitmap.save(folderName + "\\userimage.jpg"); //your original concatenation had an error
Solved!
string folderName = #"C:\temper\temp\"+userid;
if (!Directory.Exists(folderName) {
Directory.CreateDirectory(folderName);
}
bitmap.save(folderName + "\\" +userimage+ ".jpg"); `Create first folder and save Thanks Mnieto`

I can find a lot of info about parsing but I would like to put them together. I am trying to get the City, State, and Zip and place them in a single Label on a winform like 'City, State Zip' here is what I have gotten to but they will not get together.
while (sqlDataReader.Read())
{
label_vendor_Address.Text = sqlDataReader["Vendor_Address"].ToString();
string vendor_City = sqlDataReader["Vendor_City"].ToString();
string vendor_State_Prov = sqlDataReader["Vendor_State_Prov"].ToString();
string vendor_Zip_Country_Code = sqlDataReader["Vendor_Zip_Country_Code"].ToString();
label_vendor_City_State_Zip.Text = vendor_City, vendor_State_Prov, vendor_Zip_Country_Code;
}
I am sure that I am missing something very simple. Help is gratefully appreciated.
Is it as simple as this:
label_vendor_City_State_Zip.Text = vendor_City + ", " + vendor_State_Prov + " " + vendor_Zip_Country_Code;
Surely, not though, as your code would not compile. Can you provide code that can compile?
