• Visual Studio Express Editions Dataset Question

• Windows Forms Specify ConnectString at Installation Time

  I want to write a C# program which needs talk to an Access database. I plan to add this program to Windows Task Schedule so the program can run periodically and automatically. Since this program needs to run automatically, it cannot take user input at run time. I also do not know where is the database file until the program is distributed to individual users. That is to say, I do not know the ConnectString until installation time. How can I solv ...Show All

• Software Development for Windows Vista Overlapping UI bug

  I've got a problem with a set of UI widgets that no longer work properly in Vista. I've got a ComboBox control...a pulldown arrow on the right and a region to display the setting on the left. Overlapping the left of this control is an Edit into which the user can type. Our software uses the combination of the ComboBox with an Edit on top of it for a very specific purpose. A ComboBox alone will not do the job. In Vista, I see that w ...Show All

• Windows Forms Any shortcut to passing a form as an argument?

  Any shortcut to passing a form as an argument I was hoping that vs 2005 would ease the problem of passing a form as an argument over vs 2003.  Looks like not.  It is very cumbersome to overload a procedure for each form, so much so that there's no reason to do it. sub XXX(frm as New Form1) Sub XXX(frm as New Form2)   etc. It's easier to repeat the code within the form.  Is there a workaround dennist ...Show All
