What kind of file format can I use to save the DataGridView's contens? Can it be the .xls format? This means I want to open the contents in Excel later. But I don't want to launch the Excel itself when I save the contents? Because Excel may not exist n the clients' machines. This means I just want to "save" not "export".

What I'm trying to do is allow the user to click on the Row Header and capture the contents of the 4 cells in the row to 4 dfined variables. I know that I can capture each cell individually by using the CellContentClick event but this would require the user to click 4 times rather then just once.

i would like to know if it's possible to save text files into my app. that way there is no folder to contain those files. i'm thinking that i might need a separate form to hold such information, like creating a new textbox for each saved file and it's content, then loading the files from that form's textboxes.

View 1 RepliesI've created a windows form in VB Express 2005 with lots of combo boxes and print and save buttons.I would like to be able to save the contents of the populated combo boxes, labels etc ie the whole form from the save button, preferably to excel 2003. However, would be just as happy to save it in the form format. The only code behind the save button I have so far is this, which just navigates me to the directory.

ByVal e As System.EventArgs) Handles Save.Click

I have used the XML serialization to save a single text and a picture in a XML file.However, I am confused on how to extend the concept further.I have a second Windows Form which has a TableLayoutPanel in which each cell has a Picture Box and a TextBox. The user has the option to set the number of rows and columns himself, so I do not know about the number of pictures that have to be saved in the XML file. Further, when the user pressed the load button, the same pictures have to come back to their original pictures boxes in the TableLayout.
How can I save the contents of the TableLayout in the XML file and retrieve them in their corresponding cells?
I have drawn some lines into a picture box as per an engineering standard. I wish to do the following:
1) Transfer the contents to an excel spreadsheet.
2) Before transferring to excel, it would be nice to add texts at four different locations of the picture box. I have tried various solutions which I found on the net but they were not very successful. The main problem with most of the solutions is that they washed the contents of the picture box which I manged to drawn after considerable pains.
