• Smart Device Development Font settings for textbox in VS2005 IDE

  Hi all, I am working in VS2005 in unmanaged c++ and I wanted to change the font of a textbox. I can probably work out how to do it by code but I am lazy and I just want to do it through the IDE. Is this possible I noticed there are font controls on the dialog box but none for the textbox on the dialog box. Even when I change the font on the dialog box the font still doesn't change in the text boxes so I guess that's a no go :( TIA, Unfortunately you cannot change the font size from the IDE for C++ projects. Here's some code you can use: LOGFONT lf; memset(&lf, 0, sizeof (LOGFONT)); int fontSize = 12; // change this to w ...Show All
