• sureshsundar007 Can't see my design form in VS2005

  Hello I have an application, I dropped a DataGridView onto it and then put 3 rows namely Event, Time and date into it. It does not connect to a database - I put the text into the rows as follows: string [] s = { sSensorEvents[iAlarmType], sRecord.Substring(25, 2) + ":" + sRecord.Substring(28, 2), sDay + "/" + sMonth + "/" + sYear }; dataGridView1.Rows.Add(s); and repeat this a number of times This works fine and the data displays when I run it.

• skinnybuddha Filter an Array

  I have an array that is loaded with any files that the user has selected in a file browser dialogue. Right now the array gets loaded with everything in the folder, but I just want it to load image files that can be used as a wallpaper. Also I would like it to grab anything that is in any sub directories as well. you could also do this: foreach(string currentFile in Directory.GetFiles(fbdWallpaperDirectory.SelectedPath)) {    this.clbSelectedWallpapers.Items.Add(currentFile, false); }   this will not select the items initially (unchecked) when the user checks them, perhaps place a button which does the randomization. private void cmdPickPicture_Click(object sender, Ev ...Show All

• prashantpsoft Using DeviceIoControl and IOCTLs from C#

  Hello, I'm currently working in a C# project where I require the use of DeviceIoControl(). It seems that there is no implementation of this function under c#, is this correct If this is the case what would be the best way of including calls to this function within the project Would it be best to create a separate project within the solution, and if so is there a link out there that goes over this type of solution/project Thanks, Devan Putting the code in a separate C# project will not in any way make it easier to call the function. It will only affect the modularity of your code. You have to call the function through P/Invoke either way. Thanks for the hint about P/Invoke Mattais. P/Inv ...Show All

• rocky_don How to force VS2005 to NOT load a .CS file in design view.

  Hi All, I have a standard run of the mill CS file, which contains a couple of classes. Actually the project has several CS files and all of them open perfectly normal except this one, which VS05 wants to open in design view. The offending item is that this particular class is based on the system timer. using System; using System.Collections.Generic; using System.ComponentModel; using System.Text; namespace MyNameSpace {     public class MyOrdinaryClass : System.Windows.Forms. Timer     {     } } As you can see this class is super ordinary with the exception that I based it on the system timer, which is fine. I just want VS05 to open this file in ord ...Show All

• doank Capture program state and resume it on other pc(device)

  I'm trying to save the program state when a application is shut down to resume it later from whatever the user left it before shutting it down. In the long run it should be possible to save the state of program, transfer the program to another device (online via network, ofline with a file) where it's dynamically loaded throe reflection. Kind of Mobile agent but not that advanced. First problem is how to get the state of a program saved to a file. Currently I'm trying something with ExecutionContext to see what this is and if it's usefull to me. Is there anyone who has done this before or has any idea how to do this Cause I'm not sure if I'm capable of doing this in the time i have and i'm certainly not a C# guru ... would ...Show All

• JRLiem Base class array to string array conversion

  System. Array myvalues = (System. Array )range.Cells.Value2; Now wanted to convert the base class array myvalues to string [] array. How should we do it Thanks! edukulla, The problem I see in your code is that arrays are zero-based in C#. This means that: vals = new string [10]; will allocate an array with 10 elements, numbered from 0 to 9, while you are trying to access vals [ 10 ], which is the 11th. Try to change, in your code: vals [ i - 1 ] = ((Excel.Range) worksheet.Cells [i, 1]).Value2.ToString (); HTH --mc I'm not sure your cast to System.Array is correct in the above code, though - it looks a bit odd. Assuming it's fine, though - Since you don't know ...Show All

• Kimbe How to set focus on control after thread exits

  Hi, Iv'e got a form containing some usercontrols. When the form loads some calls that manipulate the usercontrols are added to a threadpool. Now on to my problem. I'd like to set focus to a control within one of my usercontrols, but if I do so before my threads exits the focus is lost. Ideal would be to have the focus during thread execution so the user can start interacting with the GUI while the usercontrol is being manipulated by the thread(s) and the focus is not implicitly changed or anything by the threads. If thats not possible then is there a way to set focus to a control after (whatever thread exits last) the thread exits and is done with the control /J If you are using .NET 2.0, you should c ...Show All
