First time it is ok. But Second time Bind is been failed. what is the wrong with the Code. Please help me out. Thanks & Regards, Uday. Re: bind(...) in tcp is failed when connected twice C++ Eugen Podsypalnikov3-Mar-10 3:44 Eugen Podsypalnikov 3-Mar-10 3:44  Dear Uday, any thread function (for an one client solution) may have - a beginning part (server: create/bind/listen/accept, client: create/connect) - a loop part (server & client: recv/send) - an ending part (server & client: close) So you have the only one call for bind Check your definition of Irrationality[^] 1 - Avicenna 5 - Hubbard 3 - Own definition Re: bind(...) in tcp is failed when connected twice C++ janaswamy uday3-Mar-10 3:48 janaswamy uday 3-Mar-10 3:48  Dear Sir, Now i Got It Thank You Very Much.

For adding custom action in MSI installation , I add one exe in Custom action. When install application using MSI, dialog box in my custom EXE is pop up, and when I click by mouse on any button on dialogbox(custom.exe), installation done smothly, but when I press "Enter" key instead of mouse click, then one MSI message popup as "There is a problem with this Windows Installer package. A program run as part of the setup did not finish as expected. Contact your support personnel or package vendor." anybody know about this error.. please give some hint.. Thanks aaa Re: Error in calling EXE in custom action (Setup & deployment project) KarstenK3-Mar-10 1:33 KarstenK 3-Mar-10 1:33  Check for your app to be topmost or systemmodal so your app gets the enter key. Or is a bug in the app. Does it run on its own properly? Press F1 for help or google it. Greetings from Germany Re: Error in calling EXE in custom action (Setup & deployment project) KingsGambit3-Mar-10 7:34 KingsGambit 3-Mar-10 7:34  Can you check if dialog box shown from the custom action is the foreground window.

But still your solution is not valid if the application is a ANSI build (i.e. UNICODE is not defined) and yes, you may use COM with a ANSI built application, provided you explicitely convert strings.

Indeed. But it doesn't automagically convert a ANSI string to a wide char one. That's why I said it wouldn't help him on a ANSI build.
