In VB 2008, I have a Parent form with a combo box on it. There is a child form also with a combo box on it. I want to be able to change the values on the child form based on what the user selected from the main form. The user launches the child form from a toolbar on the Parent form. The following code is run:
[Code]...
What I want to do is if the Parent's combo box has "Red", "Blue", "Green" values and the user selects "Green", the child form's combo box(With the same values) will also change to "Green". (I do not need to change the Parent form if the child form changes.) I've tried changing the Child's combobox from the combobox's change event on the Parent form, and the code runs, but nothing changes on the child form.
I have a need for an application with a SQL database back-end. The application will run on a laptop and will therefore be used both on and off the network. I can write the app and I can link it to SQL over the network. I also know how to dynamically change the connection string so I can handle online/offline data source connections. Where the data can be stored on the local client? I'd like the data to be held in the central SQL DB and to automatically copy to the laptop upon connection to the network. The client data source is read-only and will not upload back to SQL. I've seen XML mentioned but that looks overly complex.

View 1 RepliesI've got a richtextbox control on a form and a menustripitem that allows me to change the font style. What I want to be able to do is to allow the user to type text into the richtextbox control; then if they change the font style using the menu only for newly entered text to change font, and any previously typed text to stay in the previously selected font. The problem I'm getting is that all of the entered text's font style is changed.

I've been researching for about half an hour now, trying to figure out if it's possible, but I'm coming up short.
I've seen some WPF examples and if it really comes to that, I'm more than willing to change the app from a WinForms app to a WPF app. I've made a WPF app before, so I'm familiar with it. But, I don't want to have to remake my entire project for this one form.
On that note, does anyone know if I can make a WPF form how I need it and just import it into a WinForm app? It doesn't seem possible, but it's better to ask than not. I'll look into this more.

View 7 RepliesI need a function that returns a control within a form based on a string name. I've tried Jim's method here, but then found out that it will not work with SplitContainers. Therefore, I feel like I need to use a recursive function, or maybe a stack. I've tried many different examples online, but I can't seem to get any to work.
This is the code for the latest try, as taken from here:
Public Function FindControlRecursively(ByVal ParentControl As Control, ByVal ControlTobeSearched As String) As Control
Dim FoundControl As New Control
For Each CurrentControl As Control In ParentControl.Controls
[Code] .....
Note that the above code only seems to return a blank control.
I'm working on a simple base form in which all the other forms in the project will inherit. This base form only adds 5 properties (at the moment) dealing with painting a gradient background. The problem I'm facing right now is when I change a property on Form1 (the test form) and click run it doesn't show that change. I also checked the .designer.vb file and when I make a change it's not added to the code behind file, I'm at a loss right now to why.

I have a form that has a large number of labels. Is there a way I can move the focus from label to label. After I move the focus I'll check if the name of the label has a certain string in it. If it does then I'll leave the focus at that label. If it doesn't I'll move the focus to the next label and check if that label name has the string in it. I just need to know how to move the focus from label to label. I was trying SelectNextControl without success. Maybe I can tab programmatically to the next label but I don't know how to do that.
