Hi,

I am trying to create an ActiveX using C#, which includes inside it a WebBrowser control.
This ActiveX is hosted in a web page (so I get a WebBrowser control inside and ActiveX inside a web browser).

Since it didn't work, I googled a bit and found this article from Microsoft which explains that it is not possible:
http://support.microsoft.com/kb/237685[^]

after googling a bit more, I found the following posting (http://www.gidforums.com/t-10613.html[^]) which basically tells that calling AfxEnableControlCOntainer solves the problem.

I made a small C++ ActiveX to test this, and indeed, calling AfxEnableControlContainer makes it possible.

My question is - what does AfxEnableControlContainer actually do, and more importantly, how can I do the same in C# ?

I am an experienced C++/MFC and .Net/C# developer, so I can take a 'low-level' solution.

Thanks to anyone who can help.

Handling autoscroll and scrollbars

Hi all, I'm having a problem that is driving me mad...
I have a tablelayout panel that can have several subpanels in a column. These subpanels must resize as the tablelayout panel resizes, but under a minimum size a horizontal scollbar must appear. A vertical scrollbar is used to scroll the content when these subpanels go out the window.
The subpanels have a varying height, that is they can be opened and closed with a button to show/hide their content.

The problem is that when I open a panel and this makes a vertical scrollbar to appear, .net first creates the V.scrollbar and then creates a H scrollbar because the Vertical one hides a few pixel. But as I said the width should resize with the tablelayout.
I cannot find a way to avoid the H scrollbar to appear only to scroll the 17 px hidden by the V scrollbar. I tried many (really too many) possible solutions without luck.

Thank you!

Check the dll of the current application where it is or check the registry/Control panel

No yar if you know the name of the dll then only you have do is
search for that dll using Operating System Search option which you find in Start Menu ......
Or go to Start Menu then Control Panel - then add and Remove programme see if your aaplication is listed there

OK i thought you are asking manually
i think while installing your appaication it should have crated some folder at specific position in machine Check that FOlder name in the machine using DirectoryInfo class. Then i think you know better than me What you have to do Smile | :)

Sorry boss i thought you want that manually Wink | ;)

The path to the exe file can be retrieved using
Application.StartupPath

If you need to figure out the path of the currently executing app, use Environment.CurrentDirectory

If your updater program has to find out where the app has been installed, write the path to the registry during installation and read it from there during the update.

Label text problem

My problem is that I cannot change the text of an label when passing label as an argument to a function in a different class. for example.

void ChangeLabelText(Label myLabel)
{
myLabel.Text = "It's working!";
}

This function is not in my main class. is there any other way to do this?
p.s. it works fine with listbox

M LN Rao2-Sep-07 21:35

Try one of the following...
1)
Label ChangeLabelText(Label myLabel)
{
myLabel.Text = "It's working!";
return myLabel;
}
2)

void ChangeLabelText(ref Label myLabel)
{
myLabel.Text = "It's working!";
}

still not working. maybe this will help.
It was working before I installed the Visual Studio 2005 version.
I didn't change any code, but now it's not working-

maybe this helps.....
The function through wich I change the label of text is actually a function triggered every second by an timer event.
I wrote a new function and the text of a label is changing.
But in this timer event function it is not changing.
I checked if timer event is actually raising every second and it is. I put a messagebox.show before the label.Text = "Whatever" and I get a messagebox every second but still text of a label is not changing. wtf???????
