• Visual Studio Express Editions Problems making a LabelArray

  Hello all, I'm having trouble making a LabelArray in VB 2005 Express Edition. First of all, I can't find an Index property when I look at the label properties. Secondly I can't use the same name on different labels. It for use in a loop: For i As Long = 1 To 4 Label(i).Text = TextBox1.Text Next i or something like that. I need a LabelArray, but how to make it in VB 2005 Express Thanks so far. If I understand it correctly there are 2 ways to achieve this. Atm I like the second solution (with M.Controls) best, as I can use the VB enviroment to add the controls visually. I came across 1 other problem though. I also want to apply this for a series of ComboBoxes. They are all on 1 form and have all to be filled ...Show All

• SQL Server Mirroring problem between pcs in different location (Witness Issue)

• Internet Explorer Development Customizing Toolbar in IE7

  I am having a small problem. I have TWO search boxes on my browser.. One for Google toolbar, and the one that was originally there on IE7... I set my default to google. I cannot find how to get rid of the original search bar (to the right of the address bar) and just keep the google toolbar search box.. There is no option that I can find to just have the top row be an address bar..Any suggestions.. I cant even tell google toolbar to take away its search box, it is automatic.. It is ridiculous to have TWO search boxes on the toolbar.. Anyone know a way I've tried everything I know.. Thx JP If you ask me, you get less options with the new, and not being able to remove stupid features (search bar)  ...Show All

• Visual Studio Team System Check Constraints ignored by the data generator

  I am using VSDBPro to generate test data, my table has a check constraint defined in a column such as ( [Field1] = 'A' OR [Field1] = 'C' ), but it was ignored by the data generator and tried to populate some random values and terminated the entire process... Any workaround for that.... Henry, Thanks for the reply I couldn't see the regular expression in the generator properties for the char field. I have installed the trial version of Microsoft Visual Studio Team Edition for Database Professionals Version 2.0.50727.251. I imported the schema which has the check constraints on the column. But the data gererator ignored that... Is a the limitation of the trial version ... ...Show All

• Visual Basic Compression Issue - SharpZip - Please Help

  Hello, I am using the SharpZipLib .dll (ICSharpCode.SharpZipLib.dll, version 0.81.0.1407) to create a compressed archive (password-protected) of 3 files. Zipping into the archive seems to work OK. The issue is when I decompress and extract the files out of the archive file. The first file in the archive decompresses and is extracted fine, but the other files are not being extracted. I captured an error that I am receiving - it is Err.Number = 5, Err.Description = "Wrong Local header signature: 0xB59E0488". I am guessing that something must be happening incorrectly during the compression of the files into the archive file, but I could be wrong. That is where I'm hoping someone can help. Here is the code that I am using to both zip ...Show All

• Visual Studio Express Editions Autocomplete Combobox

  I'd like to mimic Access's autocomplete combobox with the NotInList event.

Please can someone help direct me to a solution in C# it shouldnt matter where you are binding it from, unbound or bound. Can you do one quick test and just do the same as above BUT dont bind the control instead, add your own custom entries (test, testy etc...) and see what happens remember there is an exclaimation mark just after the first opening bracket after "if" - it means "not" in case you didnt know ;-) if (!..........) { .. ...Show All

• Windows Forms Handle CRTL+A with a ListBox

  I'd like to handle CTRL+A in my ListBox to select all the items. I check for Keys.A in the KeyDown event of the ListBox and then check if control was pressed. If so I select all the items in the list. This is working. However even though I'm setting e.Handled = true the key is bubbling up and then it selects the first item in my list that starts with the letter A thus unselecting everything else. private void lstImages_KeyDown(object sender, KeyEventArgs e) { switch (e.KeyCode) { ... other key checks removed ..... case Keys.A: if (e.Control) { SelectAll(); e.Handled = true; } break; } } Ok, got it.
