EM_SETCHARFORMAT no working.

[xandaz]

    It seems to be working after all. Thanks!

    And btw JJ. I'm using the MASM32 SDK exactly as it came only with the addtion of the winclasses file.

Right, the Masm32 SDK is not the culprit. Line 278 of mdi.asm:

   Is it wrongly initialized? I thought worked. The first member of Struct being it's own size: chSTRUCT CHARFORMAT  <sizeof CHARFORMAT,<other uninitialized members>. Anyway i don't see a real problem there. The problem is the Font dimension. That's what i was looking to get help for. Thanks

Here is some functions I have used for richedit to change color and put a wavy red underline under spelling mistakes or coding mistakes or other words or letters of interest:

   Thanks for your examples. I'm still haveing trouble. The EM_SETCHARFORMAT dones't work. It gives ERROR_SUCCESS but there's no change to the edit control.  Strangelly CHARFORMAT2 seems to work if I don't use UNICODE. ty
