I have a question about how to select a tab which is on form 'Record' by coding a bit on the form 'Orders'I tried this but I get nullreferenceexception.
I am calling this when opening the orders form from the record form
Dim f As New Orders f.Show(Me) once I am done with orders form I am calling this to select the required tab on the record form CType(Me.Owner, Record).Tabtabs.SelectedIndex = 7
I am using VB2008 Express and a MSSQL Server 2005 db by the way! I have a comprehensive SQL statement, which should fill my Grid:
DECLARE @Sum NUMERIC(9,2)
SELECT @Sum = SUM(I_LS.lmenge)
FROM dbo.lfs AS I_L
[CODE]...
Now here is my problem! I want to have a form with a datagridview that displays all of the values I am querying. This shouldn't be a problem I guess. However, I have no idea how I can integrate two textboxes that can be used to enter the selection criteria (WHERE I_L.lfsnr LIKE '%1253') AND (l.sped_journal = '11-08')[/SIZE]. I have googled and read many threads so far but didn't stumble upon anything that would suit my needs and answer my question. Maybe it's just too elementary!? By the way, it is very important that the input of textbox1 ((WHERE I_L.lfsnr LIKE '%1253')) is linked to 3 positions in my SQL query to define the search criteria!
The worst thing is that I don't want to have a bindingnav displayed! I do not need any delete, update or add functions just the select option, however!
I have an application that when ran I can not seem to be able to move the form. When I try to select the cancel (x) button on the form nothing happens. I am lost as to why I am unable to select the form and move it or close the form.
View 1 RepliesI have multilingual application that was done in VB2005.We recently had a request to translate the application to Arabic (Egypt), so I have been happily running through all of the forms and changing the layout for Right to Left format.I have 2 forms that are problematic though.On one form, whenever I select Arabic (Egypt), it will automatically switch the selection to Arabic (Saudi Arabia) and try to add an ar-SA resx file.On the other problematic form, if I choose Arabic (Egypt), the IDE will automatically select Chinese (People's Republic of China), then copy the contents of my ar-EG resx file into the zh-CN file, overwriting all of our Chinese translations and layout changes with the Arabic ones.

Another thing I plan to achieve is also a random number generator that will display a number on a ball that rolls on to the screen. So the displaying of a number will be timed to show up when the ball comes in focus. I have some code that I have used previously to generate a number, but I wanna get the generated number to show in time with the ball rolling up.What are some wait commands to use in vb .net? This is the code I am using to randomly generate a number.

View 4 RepliesI would like to display my splash screen for a set amount of time (5 seconds). While the splash screen is displayed, I added code to the load function to determine which form to load next. I have the splash screen selected in the Application Properties settings. I also have to select a "Startup form:" in the Application Properties settings.
I'm having a couple of problems. First, the form selected in the "Startup form:" is loaded and displayed along with the splash screen.Next, the form I select in the splash screen load is not started. Only the "Startup form:" is loaded.
Ok, so i am trying o make it so that a user can change themes, i have moved all major code to a module so it can be accessed but then i have a problem.
I have 6 forms, all forms are the same just different themes, The problem is that in the module it calls form1, like for example form1.webbrowser.blah.blah, if i user used form3 for there theme then this dones not work as in the module it calls form1.
Basically i need to add something else there like for example:
dim Cform as string
Cform = form1
Cform.webbrowser.blah.blah
But form1 can not be a string
I wanted to select the row the user was last working on in the datagridview. So I created a setting to contain the row index. But then I had trouble using the form load event to select that row in my datagridview. It would always select the first row. I then moved the code into the DataBindingComplete event and it worked like a charm Example:
Private Sub dgvTaskList_DataBindingComplete(sender As Object, e As System.Windows.Forms.DataGridViewBindingCompleteEventArgs) Handles dgvTaskList.DataBindingComplete
[code]....
PS, if you want to select the full row, make sure the DataGridView Selection Mode property is set to FullRowSelect.
I built a form that has 3 Listview objects. Each Listview contains items, the user is to select an item from a Listview and click a button that moves the item "up" or "down" to an adjacent Listview.I am having a difficult time "knowing" which Listview item has been selected. The problem arises once a user has clicked items from different Listviews. Even though, visually, only one item is selected in one Listview, the program still detects a selection from other Listviews.

View 3 RepliesWhen I select a standard windows form at design time, then in the toolbox, under the "general" section, there are ellipse, line, and rectangle, but they are all gray and so can't be used and I can't find any way to make them not gray and thus usable. What am I missing? The help system tells how to USE them but nothing about how to make them accessible, it just assumes they are.
I have no problem drawing a line on a form at run-time but I want to drop one on at design time and can't find any way that's my real problem.I'm not a heavy user of VB.NET so I figure there's probably something simple that I'm overlooking.

Using the following code
ControlCommand("Test Form", "", "[NAME:ctlMsgQueueCombo]", "ShowDropDown")
ControlSend("Test Form", "", "[NAME:ctlMsgQueueCombo]", "This is my default value (TEST) - First")
or
ControlCommand("Test Form", "", "[NAME:ctlMsgQueueCombo]", "ShowDropDown")
ControlSend("Test Form", "", "[NAME:ctlMsgQueueCombo]", "select", "This is my default value (TEST) - First")
It selects the combo box but not selecting the desired "this is my default value (TEST) - First" from the list. Basically what it is doing is selecting any value that starts with t . e.g first value is "TMP". So instead of exactly matching it is selecting any first character match.how to force it to select the exact string from list.Also tried using the following code but nothing seems to work
