I want to get a list of installed applictions and display it in a form - the name and its icon. I have found out how to get the path. I know this much that all the application names can be found inside the registy HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\. How do i get the application icon because even though i have the application name. I dont have the path. There surely must be some way cause i can the icons in the Add Remove applet in the Control Panel? I cant seem to find anything abou this on the Internet!!!

It looks like there's a DisplayIcon value in some of the registry keys for the installed apps. You could use that. Otherwise, I believe the way that Windows does it is by looking for the EXE in the InstallLocation value, which all of those keys provide, and then grabbing the icon from it.
Picture a huge catholic cathedral. In it there's many people, including a gregorian monk choir. You know, those who sing beautifully. Then they start singing, in latin, as they always do: "Ad hominem..."

Dont' know if this is the right forum but here goes !
I have an ActiveX control which I wrote (in VC6) and I am trying to use it in a C# Web App.
I have run it through AxImp.exe and now got a couple of dlls and a cs file.
Does any body know how I can now add the control to my C# page ?
Hope some body can help.
Cheers,
Users.

Are you using Visual Studio? If so, just add the ActiveX dll to the Visual Studio toolbox, then drop it on your form as if it were a standard .NET control, VS will do the AxImp for you.

I am using VS 2003, when I add the ActiveX Control and build the project, it does not create anything and I can't access the control as it does not have a variable associated with it, any ideas ?

Are you adding it to the VS toolbox and drop it on your form? Or did you just add it to the project references?

Hi,
I added the activeX to the Toolbox and then dragged it onto the form but when I look as it's properties, it only shows the HTML properties, I can't see a way to give a variable which I can access from functions in the cs file.
Any ideas ?
Cheers
Users.

If you dropped it on the form, it created a variable for you. VS usually assigns the name ax[componentName][number], so if you dropped the WebBrowser control, it would generate a variable named axWebBrowser1.

I tried adding the WebBrowser to the form, and nothing was created.
It does as you say if you drop the control onto a windows form but not a web form, any ideas ?

Lol...yeah, the WebBrowser controls is a Windows forms control, not a web forms control. That is where you're going wrong.

I think we are talking via crossed wires.
My original problem is that when I add any ActiveX control to a Web form, I dont know how to access it from the c# code as it does not create a variable.
I used the web control as an example to prove to myself that if you add a control to a windows form, a variable is created.
I do not intend to use a web control on a web form, that would be silly I agree.
Is it possible to do what I want or can I only add special web form controls to web forms ?
Hope you can help,
Cheers
Users.

I don't think you can add an ActiveX control to a web form. My understanding is there is something extra that needs to be done. I don't know though, you should ask that question in the ASP.NET forums.

Hi All,
I'm new to C#, my first application should read a binary file in which each element is defined as a 'struct' in a C-style include file. This file is shared with C applications so I cannot modify it to fit the C# syntax.
What's the best way doing this?
TIA,
Cabbi

You can redefine the struct in C# and use it from there as if it were a C struct. For instance, here is a a C# equivalent to widely used POINT C struct:
[StructLayout( LayoutKind.Sequential )]
public struct POINT {
public int X;
public int Y;
}
I can now pass this POINT to a C function that takes the POINT struct as defined in C. Note that the LayoutKind.Sequential is necessary for interoping with C code; this attribute tells the CLR to layout the struct in memory exactly as shown in code, which is necessary for C to work with.
I recommend using this site[^] for correct interop definitions and practices.

Hi, codeprojecter
I use "checkboxlist" to show some information of the registeruser
-------------------------------------------------
for example:
I have 4 items in the checkboxlist,when first run there are 4 items in the page ,and when I check 2 and then click the submit button, the page will refresh and just show me the checked items,don't show unchecked items.
-------------------------------------------------
I don't know how to do this thing,
my code is below:
private void submit_Click(object sender, System.EventArgs e)
{
for (int i=0; i<(this.chkboxGroup.Items.Count-1);i++)
{
if (this.chkboxGroup.Items[i].Selected)
{
//I don't know the code here,please help me!!
}
}
}
-------------------------------------------------------------------------
Thank you very much!

Try this:
private void submit_Click(object sender, System.EventArgs e)
{
for (int i = 0; i < this.chkboxGroup.Items.Count; i++)
{
if (this.chkboxGroup.Items[i].Selected)
{
this.chkboxGroup.Items[i].Remove(this.chkboxGroup.Items[i]);
i--;
}
}
}

Thank you for your replay!
But, the "chkboxGroup.Items[i]" doesn't have the method "Remove"

Ups, my fault 
this.chkboxGroup.Items.Remove(this.chkboxGroup.Items[i]);

I need a robust way to insert some hidden information of 2 bytes in a text file which should not be visible in a normal text editor,I can't use Alternative data streams as when we unzip them the info gets lost,Plz help!!

There's no way to completely *hide* 2 bytes, but you can crypt them or scramble them so in the notpad will be shown 2 little squares...

Is it possible (e.g. with reflection or by using some debugging-/profiling-API) to write a class that is aware of the context where it is instantiated?
E.g. something like this:
class SomeClass {
void A( int i, string s )
{
ContextDumper cd = new ContextDumper();
string d = cd.Dump();
...
}
}with function A being called like this:
void B()
{
SomeClass sc = new SomeClass();
sc.A( 10, "hello" );
}And cd.Dump() returning a string like this:
Hi, this is ContextDumper.
I was called inside the following function
with the following paramters:
SomeClass.A( int i=20, string s="hello" )Is this possible? If yes, how?

Look at system.diagnostics.StackTrace and StackFrame.

Yes, thanks; but these classes do not tell me with which current parameter values the method is called.

The only way I know to get the parameters like this is to use enterpriseServices and setup a context for the object. Here is an example of the technique.

I don't know of any way to get the actual parameters in regular code.
