The question was, to do it without extracting them first.
Point is, that i have some example programs that do not have in included icons but show them in the menu. They aren't written in c# so maybe its something c# cant do, but i like to understand how it works.
Nothing is impossible, but to understand a woman.

Hi,
I am still new at C# and am coding an app that has tabs and on each tab is a treeview. I need to figure out which tab is selected and wich node on the treeview is selected for the current tab when the user clicks on certain menus.
I found a way to do it, but was wondering if there was an easier way.
TreeNode node;
string tabName = _tabs.SelectedTab.Text;
switch (tabName)
{
case "One" :
node = _tvwOne.SelectedNode;
break;
case "Two" :
node = _tvwTwo.SelectedNode;
break;
case "Three" :
node = _tvwThree.SelectedNode;
break;
}
Thanks in advance.
Sean

If you only have TreeViews on the tabs, you could use this code:
TreeView tv = ( TreeView ) tabControl1.SelectedTab.Controls[ 0 ];
TreeNode activeNode = tv.SelectedNode; Or, to get really terse:
TreeNode activeNode = ( ( TreeView ) tabControl1.SelectedTab.Controls[ 0 ] ).SelectedNode;

In reference to my previous post, you can use that code with TabPages that have more than just the TreeViews on them. You just need to ensure that the TreeView is the FIRST control added to the TabPage.

Search CodeProject or the web for "single instance application". There's some decent articles on CP regarding this, for example, here[^].

 Hi, I have a form that launches an external shockwave flash program and need to check, first, if the flash player is installed on the PC. Any ideas?
Thanks ahead!

You check for the existence and validity of the HKEY_LOCAL_MACHINE\SOFTWARE\Classes\ShockwaveFlash.ShockwaveFlash key and its subkeys.

Hi
In a manual from a beamer i found following command data to switch the beamer to Power On.
02H 00H 00H 00H 00H 02H
What does this line means? Are this Bios Interupts?
I try to get this Data to the Beamer using System.Io.Ports.
But i don't know how. As a string? As a Byte?
System.IO.Ports.SerialPort sPort = new SerialPort("COM1", 38400, Parity.None, 8, StopBits.One);
sPort.Open();
sPort.Write( --> What? string? byte[]? char[]? <--)
sPort.Close();
Best Regards

hi.
how can I use a button that I created in a graphical program (such as photoshop) as a traditional button in my form?
Best wishes

Just save the picture as an image file, then in your form, set the .Image property of a System.Windows.Forms.Button to your image.

Hi,
I have a Web Based C# program that is calling a legacy .DLL file made up of approximately 250 routines to perform credit card authorizations. I'm receiving a System.NullReferenceException somewhere within in the .DLL.
Once the Web C# program calls the initial .DLL module, I lose control of the debugger until it returns. The exception handler in the Web C# program is sighting the initial module as the one that had the NullReferenceException, however I know this is not true.
How can I obtain the real routine that is having a problem? What would be even better is an approximate line number within the routine. I have the source code to the DLL and can add something in there. I just don't want to add printf routines all over it saying, I'm here, I'm leaving.
Thank you,
Glenn

When you run your app, just attach the Visual Studio debugger to the native process via Tools->Attach to Process...
Also, since you have the source, why not just create a Visual Studio solution with your legacy source as one project in the solution, and your Web C# program as another project in your source? I imagine Visual Studio can take care of the details from there.

Hi Judah,
I tried to do what you suggested, Tools->Attach to Process... Selected Internet Explorer, clicked Attach and then clicked the check box for Native. Pressed F11 to step into the call and it didn't stop at the error in the DLL.
I thought of creating another Visual Studio project for the DLL, however when I tried to compile it, it took me several hours to remove the error messages from just one of the 250 routines. The .DLL is built with Watcom's 10.6 compiler and is a standard windows DLL.
The C# routine for the web has a try and catch block. Maybe I can add one of those to the C DLL entry point and print out the information. I'll have to go digging in the garage for the Watcom Manauls.
Your thoughts?
Glenn
