I fail to see what this has to do with VB.NET, but...
To unregister the .DLL, if it has such a capability, try supplying the full path to the .DLL to REGSVR32:
regsvr32 /u "C:\documents and settings\someone\somepath\dllname.dll"
If it comes back and says that the "DLLUnregisterServer entry point was not found", then you could just delete the file.

You'll have to enumerate through all the treenodes and their child nodes collections to find the Text your looking for. Just write a small little method that calls itself recusrively to find the node and select it.

Environment
---------------
Visual Studio.NET 2003 Version 7.1.3088
.NET Framework 1.1 Version 1.1.4322 SP1
XP Professional 5.1.2600 SP2 Build 2600
Problem Description
-----------------------
I have an mdi parent form.
When it opens it creates 2 instances of the same mdi child form.
The mdi child form contains a textbox and a button.
In the keydown event of the textbox I trap the enter key and display the
contents of the textbox.
In the button click event I display a message box "Click".
When the application runs the 2 child forms are created and the second child
form has focus.
Using the mouse set focus on the textbox and press enter. The message is
displayed as expected.
Now use the mouse to set focus on the first child forms textbox and press
enter.
This time the button click event fires !!
Next set focus on child 2 textbox and press enter - this again works ok.
Finally return to child1 and press enter in the textbox - this now works and
displays the correct message.
If you take the button off the child form the problem doesn't occurr. Also
when both textboxes are working correctly it breaks again if you click the
button, select the other child form and then return to the original child
form.
I have included the source for a test app using VB.NET but the same problem occurs when using C#.
Looks like a bug to me but I would be interested to know if anyone else has
experienced this problem or know how to prevent it from hapenning ?

If I remember correctly, the first click will set the focus to the new form, the second click will actually give the focus to the control on it.

Yes - thats right but when I run this test app I can click as many times as i like on the form to give it focus but the button_click event always fires instead of the textbox_keydown event when I press enter in the textbox.
Also - the fact that I am trapping the enter key press is not important - it behaves the same when trapping any other key so I don't think that accept button behaviour is important here.
Once in this state the opnly way to recover the correct events firing is to move focus to a different child form and then move focus back. At this point everything is magically ok again until you perform the following steps again
click the button on child1 and say ok to the 'click' message
move focus to child2 (click the window handle for example)
move focus back to child1 (click anywhere on the form)
give focus to the textbox on child 1 and press enter (you should see the contents of the textbox displayed in a messagebox but instead you see the click message meaning that the button_click event fired when the textbox_keydown event should have fired.)
This happens every time i run this app and does the same thing when written in C#.

I tested your app in VB.Net 2005, I didn’t find anything wrong, but when I set to child form’s AcceptButton property to Button1 your problem occurred.

Thanks for checking but I am definitely getting this problem every time i run the app (unless i've lost it completely !!).
I'm using the 2003 version of VS.NET so it is possible it has been fixed in your version.
I'll try get hold of 2005 to test it.
Thanks again...

Ok -I have tested this using VS.NET 2005 and the problem doesn't happen. I guess this is a bug in the Windows Forms dll of the .NET framework v1.
Was looking for a good reason to upgrade so this will do.
Thanks for the help :¬)

First: this should be in the ASP.NET section.
Second: define what you mean by open. This can be interpreted in various ways...

Hi Guys,
I'm trying to develop a simple pocket pc app and want to use an xml file to store the data of my custom settings class.
I can't find a way to use the built-in xml functionality of vs2005. I can use system.xml etc in a normal (ie desktop) app but mobile is being a pig.
Is the xml functionality at all supported in vs2005 mobile sdk?
Thanking in advance for your time
PS: Aplgz if this is a dumb qstn!

Hi there ,
I have just joined this forum . I want to access the serial and parallel
port through Visual Basic . Where can i get the free software to do that
and the respective drivers (in case needed).
Thanx a lot for ur help

Welcome to The Code Project.
Depends which version of VB you are using. If VB 6.0 you'll need extra bits. If VB .NET 2005 (.NET 2.0) I believe that there is inbuilt support for those ports.
In any case, there is a whole lot of info on The Code Project. Just search for parallel port or serial port articles (Search function at top of page). That'll reveal many good articles and "how-to's".

Thanks in advance..

You want to make the xml/xsl part of your project file ? You can do that if you want, but I don't see any reason to, unless of course you want to embedd them in the exe. In that case, just add to the project, and then change their type to 'embedded resource'.

My applcation is selecting a file on a list box.
When click the file, the image file will display in a picture box.
The type of image maybe .jpg, .bmp, .png, .tif.
The size of the image around 2000*2000
How can they use me 100MB memory to render each time?
What I do is just image.fromfile(filePath)
How to improve the memory usage?
|
|
|
|
|
2000x2000 = 4 million pixels. Each pixel takes 4 bytes in a 32 bit image. So that 16 million bytes. That's 156 MB. I guess your image is 24 bit, that would come to around 100 MB.
Why are you using an image that's bigger than your screen resolution ?

Thank you first,
actually, I am going to write an application like viewing photo taken by Digital Camera.
What I would like to know is, when we using viewing photo software,
like painter or IrfanView.
They won't use up such large memory.
