Hello
I have a VB.Net project which is a WPF Windows App. I took the XAML code sample from the MSDN page 'Viewport3D class', and I wrote the VB.Net version of it. I placed the Viewport3D control by code, as in the C# sample located on the same webpage.
The compilation of the VB code had no errors. However, the control in question does not appear on the form, while the C# version worked just fine.
The question I have is: Is there something I could do to solve this or is it the 3D WPF feature which does not work for VB ?
Th answer would be very helpful for me.
Thanks

Whatever is programmed in C# can be done in VB, regardless of the XAML used (XAML would not have to be converted in this instance). Since I am assuming you were looking at both codes at the same time, I would assume you missed an important chunk.

Thank you for the answer.
However, I am new to the WPF technology and would need a hint on what to do with the code I wrote. It is based on the XAML code, because I intend to obtain the same result by procedural code, instead of the designer one. That is, I could deliver you the VB code or even the entire project so that we may figure out the problem. If this is necessary, please inform me (email: cristi2go@yahoo.com).
With regards,
cristi2go.

Well, since it sounds like you ditched the XAML aspect altogether and converted it to procedural code, then I am not quite sure what to tell you. Even I am having problems converting XAML to procedural code. I am somewhat interested in the code that you are working, but I am completely busy all summer and would have no time to look it over, sorry. The best advice that I can give you is to continue to study MSDN documentation/CodeProject/google results/ and possibly buy a good programming book on XAML. Many of the Apress WPF/XAML books I would not be able to code without.

Hi,
My application requires a long process of going through selected rows in the DataGridView and calculating things, this must be done on the main GUI thread. The user needs to be able to cancel this process but otherwise not have any interaction with the main GUI. I need a popup Progress Window (progressBar, label,cancelButton...) that will tell the user how much of the process is done and give them a chance to cancel.
I think I need to create a new thread that will launch a progress window, the progress window will launch a process located on the main thread, and the main thread will comunicate back to the progress window how things are going. I've lookedd for many tutorials but they've all focused on running work on background threads using public variables.
Also, I am still very new to programming and this is m first real application. I ask you explain things in as much detail as possible.
Thank you!

Why do you think so?

No, that's not possible. Only the GUI thread can open windows.

So what's the best way to do this then? I'm going to be coloring 5000 data grid view rows different colors, I need to show the user the progress.

Why color so many rows when the user is only going to see a few at a time?? You got some ginormous monitor you're not telling us about?
|
|
|
|
|
Only 15 or so rows will be seen at once, but the Data Grid View will be displaying all 5000 rows and the user will be scrolling looking for certain patterns.
This is a scientific program where users will be generating copious amounts of color-coded rows and will need to detect patterns as they scroll. THe only other way I can think of is to paint them as they scrool by, but that might be too slow as well as constantly hang up the GUI.

Do the work in a background thread and store the results in a synchronised queue. Run a timer in the GUI thread that get the result from the queue and puts them in the grid.
Search the forum for SynchronisedQueue, and you'll find an implementation that I did a while back.
Despite everything, the person most likely to be fooling you next is yourself.

This is a double post and you apparently did not take my suggestion from the first time

Hello,
I have got a question regarding the textbox-control.
Is it possible to resize the input area of a textbox (in a inherited class) by keeping the controls width and height unchanged?
I want place a button right next to the input area. If the user presses the button (or the F4-Key on his keyboard) the textbox should open a Lookup-Form (this is not the problem). This can easily be done by adding a button-control to the ControlCollection, adding a handler to the button's Click-Event and overriding the PreProcessMessage-Function for checking the F4-Key. But I couldn't find out, how to change the size of the input-area, so that the button and the textbox doesn't overlap eachother.
I tried to write an User-control. This works nice, but the User-Control hides all of the Textbox-Properties which I need. So I had to write some kind of wrapper to make them visible again - and this is not really nice.
I would be pleased if someone could give me a hint.
PS: I'm sorry for my bad english-skills.

Your best bet is to do what you're doing. The textbox is a nasty control, very difficult to derive from b/c it paints itself outside of it's paint event.

Please read this if you don't understand the answer I've given you. If you're still stuck, ask me for more information.

Hi Christian,
thanks for your reply. I've wondered why overriding the OnPaint-method does not do anything. Even setting the eventargs to nothing doesnt prevent the control from painting.
I've got two fuether Questons:
- Could you (or someone else) give me a link to the "internals" of the Textbox-Control (MSDN just explain how to make use of the properties, painting is not explained there).
- The Textbox-Control has a nice sizing feature: If Multiline is disabled, the control's height can't be set by Drag'n Drop in Design-Mode. I would like to have such a feature in my UserControl too. How can this be done?
