[Code]...
Now imagine theres a string with : "2-12-2009 | 11:30"How can i delete a listbox item if the string matches the listbox item text after the arrow?It might sound a bit confusing but what im planning to do is to delete a listbox item based on the date of the event and not the date of the alarm.

I'm working with referenced VB6 DLL's. The problem is that the results of a method/function call are not the same. Below the code examples:
First VB.Net Dim Validations() As String myErr = myEntry.ValidateLine(Validations)
When validation fails, the string array Validations is filled with the error description string. I've tried to accomplish the same in C#:
private string[] valArray = null;
sdkError = sdkEntry.ValidateLine(valArray);
Does anyone have an idea why I can't get C# to fill the string array? Additionally, the function in VB is called with ref to a System.Array ValidateLine(ref System.Array ValErrors), perhaps it has something to do with this?

I want to auto fill a range like this:
In Sheet1!A1 i have the formula "='Sheet2'!D1"
In Sheet1!A2 i have the formula "='Sheet2'!H1"
In Sheet1!A3 i have the formula "='Sheet2'!L1"
Now the Sheet1!Ax increments with +1 value; The Sheet2!D repeats again with D, H, L but only with a +4 to all 3 of them

I want to write a quick program that fills a 2D array with quiz scores. Consider there is 5 Students and each have completed 3 Quizes. I want the program to display a class average as well as a student average.
I've gotten as far as a nested for/next loop but I am stumbling over the language for accumulating and displaying the average.[code]...

I'm making a program where the user fills out info, then they click one button and the program takes a screenshot of the form, then they click another button and the screenshot gets saved. I'm having a couple problems with my code though. For one, I'm trying to make the screenshot go to an invisible picturebox to make saving easier, but I cant figure out how to make the image go to the picturebox. The other problem is that I want it to automatically save without showing the dialog, but so far, it won't save.
Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click
TakeShotOfScreens()

I am developing an application, for a university project, which is using GDI to draw a flag, my application is also equiped with an undo stack, which is, essensially, where the problem is, so what happens is: I push the draw button to draw a box, when I do that, the solution normally creates the box and stores the object to the undo stack; however, when I ask it to undo the box, and refresh the panel, it randomly adds, endless threads to the undo stack, additionally, everytime that I set the panel to refresh in the undo procedure, it affects the draw procedure; therefore, when I tell it to draw a box, it fills the undo stach with five threads at a time, sometimes, it fills it with much more than five, and sometimes it keeps filling up the undo stack, untill I stop the debugging proccess. This is my code:

I have a VB .NET (VS 2008) application which allows the user to drag and drop a xls file onto the form and a DataGridView fills with the xls sheet data. The user than can apply changes to the data or add entries. Data integrity is checked during the load into the DataGridView (duplicates are removed and invalid entries are filtered out). After doing all this the user can click a button and the data is uploaded to a SQL server (2008) DB. I have a primary key set up (row number) and I have a compound key in the SQL table.
It is all working beautifully. Now here is my question:
I want to check for duplicate entries (between SQL server and DataGridView data) before the data is uploaded and commited to the table. What would be the most efficient way to that?

Combo box 2 is filled based on a selection made in combo box 1 and a listview is populated based on the selection made in combo box 2.When the LostFocus event completes in combo box 1, it hits the LostFocus event in Combo Box 2 but it shouldn't. How do I prevent this from happening or if I can't prevent it, how do I work around it? The following is the code used.
Private Sub cboCategory_LostFocus(ByVal sender As Object, ByVal e As System.EventArgs) Handles cboCategory.LostFocus

I am trying to add NewRow to the database by using datatable in dataset, but before I do that I want to make sure that row is not already there. I create new row for the datatable I am working with, fill it with information. I fill datatable with the row from database that has the same primary key as my NewRow by using tableadapter.fill method, but when I do that my NewRow that was never added to the datatable is filled with information from database(and not information that I assigned to it). I count rows in my datatable before I fill it and it's 0, so why is my NewRow affected by Fill command? (I am using VB.NET 2005 Framework 2.0)
