As far as I know textboxes are always Text only oterwise they have to be richTextboxes.
Who has created the excel sheet with a lot of textboxes. Why are not simple the cells used for showing text ? Or do you talk about the cells itself naming them textboxes ?

So if there are really textboxes there in excel then use macroeditor to read out their name and how to get access to them. When you get the macrocode post it here for help to transfer it into C#.

Simle switch macro editor to record then add some text into the different Textboxes then look what code you get.

BTW this way you also can try what happens when fillng one textbox withore then 255 signs. If you get in trouble then you know that this is depending on your excel sheet. if not post the code how you transfer the data

I didn't know exactly what u r telling,i didn't work before on macrocode.Could Please give any sample code link to do this.I am talking about TextBoxes on the Excel not cell because Textbox has more capacity than the cell.

Sorry I never worked with textboxes in excel before. This things there normally are working with use of VBA So I dont know hoe to access them in C#
