Populating Text Box On DropList Index Changed Not Working?

Aug 15, 2011

I am using the following code to populate text boxes based on a drop down list index change event

Private Sub DropDownList1_SelectedIndexChanged(ByVal sender As System.Object, ByVal e As WinControls.UI.Data.PositionChangedEventArgs) Handles DropDownList1.SelectedIndexChanged

[Code]....

The code works until it gets to the last item if there is only one item in the dropdown box it does not populate the text boxes, if I loop through the code it is going to the droplist index change but it goes from dr.Read() and just jumps to dr.close() without populating the text boxes?

Populating PictureBox Has Stopped Working?

Mar 29, 2011

PictureBox1.Image = My.Resources.ResourceManager.GetObject(z)
PictureBox1.Visible = True
My.Application.DoEvents()

I've just added a load more image files, bringing the total up to 108.When the program reaches this point, (above) it fails with a 'Can't find File' error.I've tried many times to reload the image files, set all their 'Build action' to 'Embedded Resource' but I'm not at all sure it's doing it. I get an error message saying 'Corrupt .resources file'. but I've opened all the files in Paint Shop Pro without a problem.I'd be surprised if there's an upper limit to the number of image files I can put in the resources file, but not as few as 108 surely ! Most of the image files are between 100 - 350 Kb but 16 are about 1,250 Kb?

Javascript - Close Child Aspx Page If Gridview Index Is Changed On Parent Page?

Nov 17, 2011

I have a parent page and child page, both aspx. All is working, but now I would like to close child page, if user leaves child popup page and goes back to parent page and clicks on something else like page index of Gridview. I CANNOT close popup child page if user goes to another app, or some other location, I only want to close if something on parent page is changed.

I have the PageIndexChange Event set up for other purposes, I would just like to add some functionality, perhaps a script manager to close the child popup page if the Gridview index is changed, java or another way which ever works best.I think I might also need to check if the child page is even open.

VB 2008 .suo File Needs To Be Changed/recreated Because A Path Has Changed. All Other Files Are OK

May 5, 2012

I changed my Username on my computer from i.e. "xxxxxx x xxxxx" to "Dennis"

VB 2008 during a compile gave me the following error: Error reading icon 'C:Usersxxxxxx x xxxxxAppDataRoamingMicrosoftVBExpress9.0VSProjectApplication.ico' -- The system cannot find the path specified.

The file "VSProjectApplication.ico" is in 'C:UsersDennisAppDataRoamingMicrosoftVBExpress9.0'

Somewhere in the VB2008 "configuration" files I believe that I need to manually change the old path to the new path.

I found the old path in the ".suo" file. The ".suo" file is not a text file. How can I edit the .suo file, save it so that it will work?

Saving Changed Data Before DataViewGrid Selection (Row) Changed?

Jan 20, 2010

on my Form I have a DataViewGrid and some textboxes with a save button (they are filled with additional data of the selected row).Save is disabled first, when I change something in the textboxes the save button is enabled.When the user changes a gow in the grid, I want to ask before changing the grid row, if he wants to save (if the button is enabled).I am using RowEnter but this is too late, then the selected row already changed (and my textboxes already got new data)...What event can I use to ask if I should save stuff before the user changes a row?Something like BeforeRowChanging with a chance to cancel changing the row?

Change Bgcolor Of Changed Text Box?

Sep 2, 2009

I have a data entry form with many text boxes/combo boxes/controls. I want to change their bgcolor everytime the user makes a change so they are aware of what changes they have made before commiting.

My plan is to store the original value in the tag and comapre in the validated event.

I don't won't to write the same code everytime I need a control to behave that way. I've never written a customcontrol before.

how to achieve this by probably subclassing the control and reuse the code regardless of the type of control it is?

Limiting A Text Changed Event?

Jun 11, 2009

I have an number of text boxes and comboboxes on different forms. I have textchanged events which trigger a msgbox if the user enters invalid data(i.e. the number they enter is to big or to small). Is their a simple way to make the program not call the textchanged event when the form is loaded and the boxes get their initial value? Second is their a way to make the textchanged only be triggered when the user enters data not when the program clears the boxes?
