I thought there was a specific property attribute for this purpose but can't recall what it actually was. eg: public void BindToGrid(IList<CustomClass> list) { _bi...
Suppose I have some code which is running in the UI thread, which spawns a new thread to do work in the background, and then goes on to do UI work. When the background work is done, BeginInvoke is called from the new thread. If the UI work is still going on, will the callback given to BeginInvoke interrupt the UI work, or will it wait?...

But when the content of the picturebox is larger then the height of the panel/picturebox no scrollbars are shown. My panel is anchored top, left, bottom, right. The picturebox is al...
I have three c# projects in my solution. One is a console app that simply calls into a class library project. The class library project does all the processing for the application. Then there is a WinForm project that displays a form and then when a button is pressed, calls the same logic in the class library project. As a result, th...

Currently I have set the TreeView to...
In SO and elsewhere it's nearly impossible to post long concatenated SQL instructions in sample code without someone politely pointing out that it's better to use parameterized input and stored procedures. Recent example here. But is it meaningful to worry about SQL injection in a Winforms project? ...
Hi, I've got two different forms in my WinForms app (MainForm and Form2 say). They both ask for an access of MyDataSet, via a "getInstance" static method. The issue is after MainForm has got an instance, when Form2 needs to get an instance the static "myDataSet" variable is null, whereas I expect to have been already set? Any ideas? ...
Hi, I've been developing C# Windows Forms applications for a couple of years and while I've heard and read about WPF I've never really come in close contact to it. With some time to spare this spring I though I'd give it a go though, but first it'd be intresting to know what you guys thought about it. What do you think, is it worth the ...

First of all, this is not about making the PictureBox control transparent. It's about bitmap transparency on the fully opaque "canvas". The PictureBox will always have the size of 300*300 with white background. No transparency is needed for the control. What I need is the way to draw the transparent rectangle (or whatever else) onto th...
