ShellExecute restriction?

[rp_suman]

I am using the ShellExecute API to launch default E-mail client like "emailto:Email Ids". It is working well but when the number of characters exceed 1852, its not launching the E-mail client. The API is still returning success code only. My default mail client is Mozilla thunderbird. Is this a restriction in the API or any chance for E-mail client? Thanks

Are you by any chance running Win2k or earlier? This article[^] may be of interest. The resulting command line may exceed 2047 chars. However, I personally find an email address that exceeds 1852 chars to be rather uncommon. :suss:

The field can have more than one E-mail, so it may exceed 1852 occasionally. I checked same thing in system with outlook/Win XP the max limit was 1863.

I'm assuming that you are clubbing too many email ids separated by semicolons? I tried by increasing the no. of email ids with every trial. At some point, ShellExecute started returning a value NOT greater than 32 (it returns a value greater than 32 if it succeeds) and the return value was, upon failure, SE_ERR_ACCESSDENIED. You might want to check the return value properly.

I think it has to do with the lenght of the commandline. What you could do is put your line in a batchfile (just generate the file from within your program) and run that one. Just delete it when ready.. Rozis

Should be rather OK as long as you don't have to spell your email ID out to someone over the phone. :laugh:
