The Windows Forms Designer in C++/CLI projects generates both the declarations and definitions of all event handlers in the header file itself. The .cpp it generates is a mere stub which simply includes the generated header and stdafx.h. I feel that I could reduce compile times if I moved the implementation (i.e. definition) of all class...
I am designing a form in c#. I want to specify the "Client-Area" of the form in the designer. The Size property sets the size of the complete form, including the NC area. Is there any way to set the client area size? ...
I'm currently using Microsoft Visual C# Express Edition (with SP1) for a Project. I'm getting some strange errors in the Forms editor when editing one particular form, the message reads: Type 'System.Windows.Forms.Control' in assembly 'System.Windows.Forms, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' is not...
I'm a user interface designer. The project I'm working on is a dashboard that will have several interactive and customizable widgets (think Netvibes, etc.). The development group is going to be using either WinForm or WPF to build the dashboard and widgets. I need to understand the capabilities of each technology better and see a sampli...
I am just getting to grips with the concept of a UserControl. I've created a UserControl to group together a number of controls that were being duplicated on individual pages of a TabControl. Some of these controls are text fields that require validation, and when validation is unsuccessful I need to display an error message. However t...
I have built a simple report and run it successfully in test winform apps but when I try to run the same report in my production winforms application, the report just doesn't show up in the viewer. I look at the ReportViewer control after InitializeComponent and everything looks fine. Are there debugging techniques or gotcha's that mig...
I have a subclass of System.Windows.Forms.TreeView that's manually "bound" to a set of hierarchical data. I want the user to be able to edit the labels of the tree, and have the changes reflected back to the data. So I set LabelEdit to true and overrode OnAfterLabelEdit to the tune of: protected override void OnAfterLabelEdit(NodeLabe...
In Visual Studio 2005, I've recently reorganized a solution with over 30 projects into 5 solution folders. However, since I've done that, all the custom controls and user controls from my assemblies have disappeared from the WinForms Toolbox. Has anyone experienced this? Are there workarounds? Is this fixed in Visual 2008? I've tried to...

I need a UserControl to display pictures as a Gallery in Winforms. I have my pictures as a Image Collection but no problem to change to fit Control capabilities. It could be nice if it is for .NET 1.1 but since I'm planning to migrate all our code to 2.0 if the control is in that framework it could be useful in the future If it is fre...
besides updating GUI controls from background threads, is there any other operations that should avoid being done on background threads in winforms? ...
I have two exceptions here. Not sure why they occur because I use Form.Invoke to run UI updates on the UI thread. So first, using System; using System.Collections.Generic; using System.ComponentModel; using System.Data; using System.Drawing; using System.Linq; using System.Xml; using System.Windows.Forms; namespace Toplr { using Sy...
I have a userControl (.NET 1.1 Winforms) that has a clickable picturebox as a button. Since I have lots of those usercontrols visible at the same time, I thought It could be nice if I just display the picture box when the mouse is over the usercontrol and hide it otherwise. To do so, I handle the MouseEnter and MouseLeave events of th...

I'm not worried about SQL Injection. 2) How to use IN with Like, and include results that have a null. 1) Unfortunately, I can't seem to find any advice for the first option since...
Thinking about this for an About dialog but I'm sure it's applicable in other places (say a find box) Sorry if this is a dupe, but I couldn't find this or how to articulate the last part about it only being on top of the parent. How do you make a form that is always on top of the parent form, but is non-modal, but doesn't cover up oth...
