View 7 RepliesWhat is the purpose of a table option in vb2008. Can text be added to a table. What are the other options to add text data in a table form? what does a datagridview do?
View 3 RepliesI am using vb.net in my project. I have a datagridview bounded to a datatable m_table which has a column called Price_Change with decimal values. I want to display text in datagridview in green if price change>0 and red otherwise. I cannot simply use the following formatting because the bounded data table m_table is constructed in my code, not directly through data base.
DataGridView.Rows(0)Cells(0).Style.ForeColor=COLOR.BLACK
Code looks like
Dim rowText As DataRow = m_table.NewRow
rowText("Price Change")=10.00 'assign values to price change column
' there is no color formating for data table I wonder if cellformatting event can be used for this purpose. Would it slow down the load of datagridview? [URL]

I am coding a program that will allow the user to input 5 payrolls for Store 1, Store 2, and Store 3. The total of the 5 payrolls are then added together and shown in the respective Store's labels. A total label is also there to add up all the totals into one number. The numbers in the label must be in currency form. My problem is the numbers don't add correctly when I hit calculate. The first two numbers add together, but then after that the number just seems to subtract a random amount.

The connection string on my dev machine is different from the ones at the clients. so each time I update I open the config file and edit the connection string setting.

View 6 RepliesIn my vb.net winforms application using Visual Studio 2010, I'm trying to work something out and my brain just isn't working today. I'm rewriting this application to make it more efficient and trying to minimize the sql calls.
Currently it works like this.User logs in to the app, it loads the main form, where the user can open up different forms to access different client data. Each time a record is loaded in one of these new forms it also loads that specific users permissions from a Sql Server 2005 table.
What I want to do is when my main form loads after the user logs in, is load a public dataset or datatable, or any other suggestion, storing that users permissions so I can access them locally without hitting the sql server every time the user opens a client record.
