Visual Basic, Adding Controls at run time

Adding Controls at run time

Author	Message
Gary Cohe #1 / 5	Adding Controls at run time I am creating a form where I would like the number of text boxes that appears depends on a number the user chooses. How can I create the text boxes as needed as opposed to putting all of them on the form and making the unneeded ones invisible. I checked MSDN library and could not find anything. TIA Gary

Stormdev Software Developmen #2 / 5	Adding Controls at run time Gary, Put a textbox on your form and set it's index property to 0 and it's visible property to false. Put a second textbox on the form so the user can enter the number of textboxes desired. Next put a command button to confirm and create the number of textboxes desired. in the command buttons click event put the following code, Dim numTextboxes, counter numTextboxes = text2.text for counter = 1 to numTextboxes load text1(counter) text1(counter).left = 100 text1(counter).top = counter * 300 ' 300 as long as the scalemode property of the form is Twips text1(counter).visible = true next counter Hope this helps, if your still unclear about this just look up "Control Arrays" in VB help.

Xichang Zhan #3 / 5	Adding Controls at run time You may do it following those steps: 1. In design time, drop a textbox control to the form, say Text1, set Index = 0 2. set this control Visible = false. 3. in running time, add the code Private Sub Form_Load() Load Text1(1) Text1(1).Top = 100 Text1(1).Left = 100 Text1(1).Visible = True Load Text1(2) Text1(2).Top = 500 Text1(2).Left = 100 Text1(2).Visible = True End Sub Quote: > I am creating a form where I would like the number of text boxes that > appears depends on a number the user chooses. > How can I create the text boxes as needed as opposed to putting all of them > on the form and making the unneeded ones invisible. > I checked MSDN library and could not find anything. > TIA > Gary

CML #4 / 5	Adding Controls at run time Look into using Load and Unload. They use controls arrays. Easiest way is to open a form in design mode. Put one text box on the form. Set all the properties that you want, give it a good name, then copy and paste it saying Yes to create a control array. Then erase that one you just pasted. Now you are back to one, but it is Index 0 in the control array of that Text box. Then read up on how to use Load and Unload to create copies of it at runtime. -- -Clint LaFever http://lafever.iscool.net Home of the Visual Basic Code Depot Add-In VOTE for my wife in the Lycos Model Search 2000 http://clubs.lycos.com/live/Directory/PhotoAlbum.asp?CG=llfae5c88va13... mohh08&AID=61792&query=fitdiva Quote: > I am creating a form where I would like the number of text boxes that > appears depends on a number the user chooses. > How can I create the text boxes as needed as opposed to putting all of them > on the form and making the unneeded ones invisible. > I checked MSDN library and could not find anything. > TIA > Gary
