What's the deal with the ToolStrip's RenderMode property?
I never quite understood what this property was designed for. I can see that it visibly changes the design of the toolstrip and I find that setting it to System on Windows XP makes it fit much better with the WinForms style. Is there some deeper meaning here? Does the way in which the control is rendered change at all and which mode wou...

Is it possible to show a selection border rather than back-colour in a DataGridView?
My DGV has row BackColors set to various colours based on business logic. When a user selects the row the colour changes to the selected row BackColor thus obscuring the pre-set colour. I would like to preserve the original colour when a row is selected and indicate selection with (perhaps) a bold border around the selected row. Is this ...

In other words, I'm looking for a session identifier or an equivalent variable. I've looked in the Application, Environment and AppDomain classes, but I couldn't fi...
How to deal with ToolStrip in Custom Windows Forms Base
Hello, I'll share my cue with everyone! My Form Base Class is frmExportBase.cs, so any Windows Form that I will create or use have to inherit from it, so this will be fine : namespace SResocentroAnalytics.Forms { public partial class frmExportCobranzaDiaria : frmExportBase { public frmExportCobranzaDiaria() { ...

Dynamically generated drop-down menu appears in upper left corner of screen
I've plugged some code into the MouseDown and Click events of a ToolStripMenuItem to generate a menu at run-time, but the menu appears at the upper left corner of the screen instead of under the menu item. It doesn't matter if the code is in MouseDown or Click, the menu is always in the wrong place. What am I doing wrong? Here's a code ...
How can I control the location of a dialog when using ShowDialog to display it?
This is a very trivial problem but I can't seem to find a way of solving it. It's annoying me because I feel I should know the answer to this, but I'm either searching for the wrong terms or looking at the wrong methods and properties. I have a configuration dialog that's called from two places. The first is from the button on the form...

I assign them different locations on the screen, but when they're shown they start with the default location and move in a disturbing way to the new locations. I tried to assign the location before I show t...
Windows Service vs Windows Application - Best Practice
When should I go for a Windows Service and when should I go for a "Background Application" that runs in the notification area? If I'm not wrong, my design decision would be, any app that needs to be running before the user logins to the computer should be a service. For everything else use a background app. Is my decision right? Moreov...

How to get the handle of the topmost form in a WinForm app?
I have a WinForm app that has other child forms (not mdi). If the user presses "Esc" the topmost form should be closed even if it doesn't have the focus. I can use a keyboard hook to globally catch the Escape but I also need the handle of the form to be closed. I guess there is a way to do that using Win32 API, but is there a solution...
