View 10 RepliesI have a main form with a number (in this case 9) mdichild forms. Some are visible, some not, but they are all very basic. When I write to a textbox in any child form during Main_Load it updates, when I write to a textbox in any child form inside its own _Load it updates. If I write to one from awhere else in code, including a sub in the form's own code, it fails to update.
All the child forms are identical but are distinctly separate forms created before compilation rather then NEW versions of a single form to avoid threading problems.Curiously this code worked once only. No edits were made and when re-ran failed after stopping it if found all the controls in some of the forms were invisibe in developer mode, restarted VS but still not there. Run app and at runtime there they were!!! Also all locked textboxes still accepting input.

I have been at VB.NET for a very short while now (about 1 month) and I can say without a doubt my knowledge of VB has continued to amplify from the information posted in these forums.Along with my first post I also have a question about setting an icon for my application .exe file.I have read that I need to go to Project > properties then on the Application tab there is a section to change the icon from the default to something else. However when I do this and choose the icon that I want, I get an error when I use the debug to run my application.It says "Unable to write to output file C:/... the specified image file did not contain a resource section".

View 1 RepliesI am using the following code to filter on a textbox value using the BindingSource.Filter function.I thought this was the right code based on my many searches.
BindingSource1.Filter = "ValueID = '%" & ValueToFilter.Text & "%'"
When do a debug, it shows the correct value which is "432360ac-ac35-4101-8d46-f2cbd5b5dc52.There are spaces in the end of this value and it is exactly the same in the SQL database with the spaces. ValueID is a column in my SQL server. It does not filter the records in my dataset.I tried replacing the ValueToFilter.Text with my actual value as shown above including the space at the end and it filters the records just fine exactly as I want it to. Although I obviously need it to work for multiple values from my SQL server.

I have a form with lots of textbox, and a dateTimePicker. All of these controls are binded to a JoinTableDataBindingSource. So when I wanted to insert a new value or update the values, I have to rebind all these controls to the respective tableBindingSource.So after saving all the values to database, I rebind them again to the JoinTableBindingSource to display the values accordingly.
All these works perfectly until I tried to bind the DateTimePicker. I am able to show the Date, insert new values to Date, and updating date.However, after all the binding and rebinding,whenever I tried to call tblJoinTruckTableAdapter.Fill (me.dataset. tblJoinTruck), All the textbox.Text becomes "Nothing". I am unable to show the values in the textbox.
Everything works when I commented off the binding and rebinding of dateTimePicker. I seriously have no idea what had happen.Below is the binding and rebinding of my dateTimePicker.'I have clear the databinding before adding this to point it back to its respective table.

I am using VB to make a file editing system that allows the user to edit multiple files on multiple tabs like Notpad++.I hit a slight snag though. Seeing as tabs don't contain text, I add a textbox to each tab upon creation.For loading files I want to check if the current tab's textbox is empty so I don't end up adding the loaded file as a new tab, which would just create clutter (like how when word opens a file, it checks if the current document is an unsaved file with no text before loading.)Problem is, how do I check this with tabs I haven't added yet? (Ie will be added whilst the program is running as opposed to in design mode)
View 2 RepliesI have a small problem with my AutoComplete Textbox in that it doesn't replace what I type with the item from the drop down list. This is hard to explain so I will start off with the AutoComplete of the combobox and how it works.
If I create a combobox with the following listitems (pay attention to case as this is the actual problem)
Item1
Item2
Production1
Production2
Now I can set my AutocompleteSource to ListItems and when I begin typing into a combobox I get a list of matches (Using SuggestAppend)So if I type i (lowercase) I get a list containing Item1 and Item2 with tem1 added and selected for overtyping in my combobox text. Now if I press Tab or Enter, My combobox.text is updated with Item1 with the proper casing from the list even though I typed a lowercase i. This is not how it is working in the textbox. Using the following code:
Dim mySource As New AutoCompleteStringCollection
mySource.AddRange({"Item1", "Item2", "Production1", "ProductionItem2"})
TextBox1.AutoCompleteCustomSource = mySource
TextBox1.AutoCompleteSource = AutoCompleteSource.CustomSource
TextBox1.AutoCompleteMode = AutoCompleteMode.SuggestAppend
When I begin typing in the textbox, again, the list drops down. And again, when I type a lowercase i, I get a list containing Item1 and Item2 with tem1 filled in to my textbox. Now if I press enter or tab, my textbox is filled with item1 instead of Item1 as it did with the combobox.
My question is:Is there a way to ensure that the text in the textbox matches the actual case of the item in the customsource? I can click the item in the dropdown and it appears in the textbox just fine. But I don't want to force my users to have to do that.
I'm trying to evade the problem of being unable to have a transparent textbox by using a label. When the label is selected, it selects the info in a textbox elsewhere. Then using Textbox.changed, i stream the text to the label. Maybe the code will make sense:
Private Sub UserLabelClick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles UserLabel.Click
UserTB.SelectAll()
End Sub
[code]....
But the text is not selected and therefore cannot be changed.
