• MigiTheGuru Focus in textBox

  Hi, I have two textboxes on a form. If I force the focus to textbox2, the focus remains in textbox1 itself. this.textbox2.Focus(); doesn;t help! Thanks, You can't set focus on the textboxes until after the Form_Load event finished. If you are using .Net 2.0, put the code in a Form_Shown event handler instead. Independant of the index Focus() will work. The problem must be something else, that is why I asked you to paste some more code. Max Where you are calling this code Make sure to call textBox.Focus() only after a form is shown or visible. Some people get cofused with this when they call it from Form's Contructor or Load event. If you are doing the same then do call this fu ...Show All

• Avi_harush ClickOnce Fails with "Value does not fall within the expected range."

  I have a ClickOnce-deployed application installed in offline mode across a range of Windows 2000/XP machines on my network. I now receive an 'Application cannot be started. Contact the application vendor.' error message when I attempt to run the application on my development machine. (It works still on the production machines.) I've run mage -cc, and renamed the '2.0' directory to '2.0x' to ignore its presence.

• Alex974 Databinding to textboxes on form using SQLExpress

  I am having trouble getting table data from my SQLExpress connected databases to bind to the textboxes in my form. I can perform a grid view of the tables data just fine. Any suggestionson what am I missing in the form design I don't have any code to show. What I am interested in is why, in the devleoper environment, I can't just bind a datasource to a textbox in a form like I do in MS-ACCESS.  This SQL Server Developer Edition is making it way too hard to do a simple task. I am saying when you elect view all the table data to a grid, that works. I want to add text boxes to a form and it complains of a binding errror when I do this.   could you please show your code,it is hard to tell you where is ...Show All

• Zadoras Keypresses in picture box

  i have a small app where users can draw shapes in a picture box using the mouse. I want the 'delete' key, when pressed to delete the current shape. But there is no way (that i can see) to be able to listen to key events for a picture box. Any ideas around this Hi speedie, There is a property called “KeyPreview” for a Form which determines whether keyboard events for controls on the Form are registered with the Form. Please set it to “True” and try again so that the events work correctly. “KeyUp” or “KeyDown” events will determine if “Delete” button is pressed (KeyPress event didn’t get fired in my app). Thanks, JDee Thanks alot, ...Show All
