Well, so long as you want to keep the code a secret, I can't hope to help you. Perhaps if you also told us how often it works, under what circumstances it fails, all the pertinent info you didn't put in your original post.

This is the font used to add fonts to my application

                    //Load the font off the stream into a byte array<br />
                    //byte[] ByteStrm = new byte[(int)FntStrm.Length + 1];<br />

Which line blows up ? This looks super nasty, why do you need to do all this ? Are you loading fonts from your resources ?

Re: System.ArgumentException: Parameter is not valid.

17-Mar-08 0:21

My other questions were 'why do you need to do that' and 'which line blows up'. How often does it blow up ? Can you reproduce it, and know it will blow up ( i.e. does it blow up every third time or something ) ? If you read your error message, it's telling you you have a name wrong. Have you tried making it so it doesn't require the exact name ?

Sir it does not show any line of error it simply give a message that Parameter is not valid. and application closes.
but when i used to make a setup then and install it on the target machine then it give such a error that i have posted in starting about JIT..

First issue you have is that this is the C# forum, and C# does not use a linker. Were you looking for the C++ forum, or have you spammed the entire site ?

MSDN is the place to search to find out what libs you need for specific C API calls. They tell you at the bottom what header you need, and what lib.
