I'm using this line to populate my combobox with all files in my application path:
ComboBox1.Items.AddRange(IO.Directory.GetFiles(Application.StartupPath))This works fine, however it displays the path as well, and I only want to display the files with extension .txt
I am having a strang problem with button event handlers that I am creating at runtime.Actually if I set the form as startup form everything is working fine but when I set the main apllication form as startup form the events for buttons created at runtime are not firing.I am posting the code so that you can have a better look and see whts wrong?I have two classes under spotlight here "Class1" and "Grid"I am creating an instance of grid in class 1 and in a sub in grid I am creating buttons dynamically as follows and adding event handlers
For i As Integer = lIndex To uIndex
Dim btn As New Button
btn.Name = ds.Tables(tblName).Rows(i)(btnName).ToString

View 7 RepliesI'm trying to get a combobox to be automatically filled from a text file and have it editable by the user.
So far, when the program is running I can add new items and they appear in the text file and combobox but when I restart the program the combobox list is empty even though the text file has stuff in it.
Dim w As New IO.StreamWriter("z:url.list.txt")
Dim linecounter As Integer

I'm using visual basic 2008 express I have 1 combobox which is populated from a coloum from my database, when I select a value from the combobox I wish to populate several textboxes with data from the row selected. I have created a dataset. How can I do this? Is there a tutorial I can read anywhere
View 2 RepliesI have seen something like the following in many software. Combo box populated and displayed with multiple columns (for example stock code, stock description). But now I am only able to populate with stock code. May I know how to achieve this? I know it can be done by calling a form (And I can do whatever coding in this form) out when clicking on the combo box. But I am looking for better solution, or is it possible to populate the whole datagrid into the combo box as source instead of only the data.

View 2 RepliesProblem drawing dotted path lines, with even dots along the path line.I want to draw a path line that can be any shape (square, round, outline etc), and along this path line I want even dots to appear.
I also want to be able to resize the shape (as in the example attached)This is very easy to do using "DrawPath" and defining points for the path and using a pen defined as dots.The problem I have is I want the dots to be evenly placed along the path, on any shape or size I draw.In the example I have created, I create a square with 4 points and draw a dotted path.There are 2 buttons that allows me to resize the square (larger or smaller) this helps show the problem more clearly.
The path starts at the top left corner and finishes back at the top left corner, the dots are evenly placed along the path, except the final dots at the end of the path. (Sometimes the dots are even and other times they are not even).The shapes I want to draw can be any size and any shape, but I have used a square in this example to show the problem I have. point me in the direction I need to go that allows me to draw the dots and give the impression that they are even all along the path, for all shapes and sizes.
In the pictures below if you change the size of the shape, one will have even looking dots, the other will not.

I have several combo controls that need to be populated with a specific ID and name. I want the user to choose the name and have the ID in the background. Later when the data is exported from the database the specific ID's are exported and not the names.
I see that I can create the items in the combobox rather easily using their names. However, how can I associate the ID number for each of the items. Private Sub frmReceipts_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
' Add receipt types to combo box
cboReceipt.Items.Add("Monetary")
cboReceipt.Items.Add("Inkind")
cboReceipt.Items.Add("NSF")
End Sub
I thought it would be better to have a seperate table with the different receipt types and then somehow connect/link the contents of this new table to the combo box on this form. However, I am at a loss on how to do this.

I tried binding a DataGridView to a DataSet using the DataSource property but no data appeared in the DataGridView. I placed a DataGridView in an empty form, making no property changes except for the name. I did not create columns in the DataGridView. In the form's load event I placed the following code for loading a dataset named ds Executing in debug mode, I confirmed that there was data in that dataset. No column headings or data appeared in the DataGridView. What am I doing wrongly? There are 34 fields (columns) in the DataSet - maybe it exceeds the capacity of a DataGridView.

This procedure will work fine and display in the browser. However, if I save the file to C:Document123.pdf, how can I access this file using relative path in MapPath function. Is there an option to access the file which is saved out of IIS server? I am using vb.net 2003.

Well now i have an issue which is pointing in the use of "path's" physical and network.I have a SQL server on a Server machine and i have a desktop machine used as client.I'm runing from my client machine a stored procedure in order to add a streaming data base.But also before i run this procedure i run another one which prepare the desired "path", this procedure takes:
myPath="\ServerSharedFolderSQL
in order to run the first procedure i have to turn myPath in each physical name:
myPath="DriveLetter:PublicWorkFilesSQL"
Now my Issue is how i will have the physical path, which is build it on the server and which it's from very difficult (to imposible) to know it? Basically i need a function which will return me the physical path, which the implementation it's not knowing to me. My developing environment is vb.net 2010?
