I have a DataGridView that has my custom class called "Account" binded to it. In my custom class, there is a enum called "Status". In the DataGridView, I want the "Status" column to be a ComboBox instead of a text field, and I want the "status" Enum options to be binded to it.Below is a example of what my class and enum look like
Public Enum Status

I have two text files, the first text file has two columns separated by a space (" ") and the second text file only has one column.
The column 1 in text file 1 and text file 2 match albeit in different order, what I'm trying to achieve is for every field in column 1 text file 2 I want to search for column 1 in text file 1 and display the matching column 2 field in column 2 text file 2.
Dim*OpenTextFile*As*String*= IO.Path.Combine("C:Test1.txt")
Dim*OpenTextFile2*As*String*= IO.Path.Combine("C:Test2.txt")
Dim*SaveTextFile*As*String*= IO.Path.Combine("C:Test2.txt")

Below is some code I use to loop through rows in a datagridview and set the row colour subject to a "STATUS" field and also changing font colour and boldness dependant on whether a flag has been set to true.
Is this code optimal / can it be cleaned up somewhat?

Dim varStatus, varBagTemp As Integer
Dim myFont As New Font(grdResults.Font, FontStyle.Bold)
For Each row As DataGridViewRow In Me.grdResults.Rows
varStatus = row.Cells.Item("Status").Value

I have a combobox which reads a directory and displays the file names in the combobox. What I'm trying to do is when a value is selected in the combobox I wish to display this in a label.
I have tried the following
Label1.Text = Combobox1.SelectedValue
But it doesn't seem to work.
My coding to display value in the combobox
With Combobox1
.DisplayMember = "Name"
.ValueMember = "FullName"

I have the first snippet of coding in the Combobox1_SelectedIndexChanged event.
The "FullName" works with textbox1 when i select a value in the combobox but I want to display the "Name" in label1.text
I am creating an application install program, but one of the main things i cannot get working is the combobox, this is a drop down list of all my applications that i have put in there. I was wondering if there was a way you could tell the combobox to look at a directory or share and list the names of files within it? So, for example i could place 5 programs inside a share or directory then when i run the program and the click the drop down combo the 5 programs are listed and then i can click and install this program. Also then if i add/remove any programs it also removes it from the combo list.

I am developing a new project for my daily office use using access database with vb 2005.
In this project I have one bounded datagridview and it is ready to use.
I want to alter a particular field value in the datagridview regularly. so whenever I click the rowheader that particular field should be editable with a combobox with some value, after selection of the value and leaving that particular cell it should be updated with the appropriate record in the database.
I can use this code to set the DisplayMember, but the ValueMemeber is always the name of the field and not the field values. I can even reverse and put the ID in the DisplayMember and it works. Not sure what I'm missing here.
strSQL =
"SELECT LGGrpMainID, LGGrpMainName FROM LGGroupMain "

Alright well i am creating a basic program, it has a login system. When the user clicks login i have timer1.start and then i have a progress bar start to fill, i want to know how to take a label, place it under the progress bar and have it display different text, as in
First message: Validating Login Credentials... (moving ... if possible)
Second message: Verifying System integrity... (moving ... if possible)
Third Message: Connecting to Servers... (moving ... if possible)
Fourth Message: Grabbing user Database... (moving ... if possible)
Fifth message: Login successful!
I want the messages to be in sync with the loading bar, but i also want to try to make my loading bar move slower and when the progress bar is finished and the messages underneath it are aswell i want it to show a new form.
im making a tabbed web browser, and wondered if i can add a label and see what the page is loading, similar to other browsers like in the bottom left EG. "Connecting to [url]" etc. Note, im using TabControl, so commands like "WebBrowser1.Stop()" etc, will not work for me.
View 6 RepliesI created form2 in which there was a Label to display processing status text. In form1 right before serial port ran I used Form2.Show() and Form2.TopMost = True to display processing status. However only blank Form2 was displayed without any text inside, which means the Label in Form2 was not running. But after serial operation was done, the text in form2 came up, at which time I need to close it.

I need to be able to double-click a row or column in a row to use a field (in this case the Student ID field, the 4th column if counting form 0) to get that row from a database onto a separate form and be able to edit and save it. I have no idea how to make this happen since it is not covered in the class beyond basically displaying database data in DataGridView, I chose to use this functionality in my final project (to be fancy I guess) with the thought that it will be easy to accomplish but am finding it is not quite as easy as I thought.
