Function Call Prob Peter Liddle5-Mar-02 11:11 Peter Liddle 5-Mar-02 11:11  Hey guys The function below is being called by rundll32.exe but whenever i run it i get a memory violation saying :- The instruction at "0x77f52ff9c" referenced memory at "0x002e2afd. The Memory could not be "read" // DLLVerifySignature - Allows Verification on double click bool DLLVerifySignature(HWND hwnd, HINSTANCE hinst, LPTSTR sFileNameAndPath, int nCmdShow) { CFullCryptFunc FullCrypt; FullCrypt.FullVerifySignature(sFileNameAndPath); FullCrypt.~CFullCryptFunc(); return TRUE; } The funtion i call in the FullCrypt class works fine as when i call it from another part of the program i have no problems im guessing that teh problem occurs because the software is not properly initalised when it trys to call this. Peter Re: Function Call Prob Tomasz Sowinski5-Mar-02 11:23 Tomasz Sowinski 5-Mar-02 11:23  You'll have to dig deeper - run your .dll under a debugger. Use rundll32.exe as 'Executable for debugging session' under Project Settings/Debug. When the program crashes, you'll be able to have a look at the stack, local variables, globals, etc. Tomasz Sowinski -- http://www.shooltz.com another quickie tbbooher5-Mar-02 9:43 tbbooher 5-Mar-02 9:43  So i have a char[20] like "foo foobar foo2" and I want to get A = "foo" B = "foobar" C = "foo2" if the words could be any length, what is the best way to do this? tim --------------------------------------- Tim Booher Re: another quickie Tomasz Sowinski5-Mar-02 9:50 Tomasz Sowinski 5-Mar-02 9:50  strtok is the key to nirvana... Tomasz Sowinski -- http://www.shooltz.com Re: another quickie tbbooher5-Mar-02 9:50 tbbooher 5-Mar-02 9:50  what about the extraction operator:  char curRecord[20];   char cDay[3];   while(!osMyFile.eof()) // we go through each line in the file   {      osMyFile.getline(curRecord,20); // read time value      curRecord >> cDay;      cout << curRecord << "\t" << cDay << endl;   } --------------------------------------- Tim Booher Re: another quickie Tomasz Sowinski5-Mar-02 9:59 Tomasz Sowinski 5-Mar-02 9:59  Will work, but you'll need strstream. Tomasz Sowinski -- http://www.shooltz.com Re: another quickie tbbooher5-Mar-02 10:16 tbbooher 5-Mar-02 10:16  i am sorry, but i don't get it what do you mean? --------------------------------------- Tim Booher Re: another quickie Tim Smith5-Mar-02 10:21 Tim Smith 5-Mar-02 10:21  He is just saying that strtok is a nice simple routine while strstream is this huge library with a lot of extra baggage. Tim Smith I know what you're thinking punk, you're thinking did he spell check this document? Well, to tell you the truth I kinda forgot myself in all this excitement. But being this here's CodeProject, the most powerful forums in the world and would blow your head clean off, you've got to ask yourself one question, Do I feel lucky? Well do ya punk? ALMOST THERE tbbooher5-Mar-02 10:30 tbbooher 5-Mar-02 10:30  o.k. so I have: while(!osMyFile.eof()) // we go through each line in the file {   osMyFile.getline(curRecord,20); // read time value   ins >> intDay;   ins >> intTime;   ins >> strOnBay;   cout << intDay << "\t" << intTime << "\t" << strOnBay << endl; } this is so close to working -- the only problem is that, while it loops through the file, it keeps putting the same value in intDay, intTime and strOnBay each time . . . (i.e. they never change) thanks, tim --------------------------------------- Tim Booher Re: ALMOST THERE Joaquín M López Muñoz5-Mar-02 11:24 Joaquín M López Muñoz 5-Mar-02 11:24  Where did that ins come from? Rewrite your code like this: ... osMyFile.getline(curRecord,20); // read time value <font color=#ff0000>istringstream ins(curRecord);</font> ins >> intDay; ...

Re: HELP Joaquín M López Muñoz5-Mar-02 9:18 Joaquín M López Muñoz 5-Mar-02 9:18  Could you explain yourself a little longer? If you want a project to depend on say some external .lib just add this file as a regular source code file. The IDE will not only link the library but also take care of relative last modified dates.

Good Luck, Bill Cookies in Winsock - How? 5-Mar-02 8:35 5-Mar-02 8:35  Hi everybody! I'm writing program, that will go to some web site, log in, and retrieve some data. I know how to get data from web server, that does not reqire any authentication. Web page I'm trying to log in is a standard form where you can enter username and password. Below is part of Java script of that page: function secure_login(form) { // Prepare session cookies for secure login document.cookie = "uid=" + escape(form.UserID.value) + "; path=/; domain=.somedomain.com"; document.cookie = "pwd=" + escape(form.Passwd.value) + "; path=/; domain=.somedomain.com"; document.cookie = "redirect=" + escape(form.redirect.options[form.redirect.selectedIndex].value) + "; path=/; domain=.somedomain.com"; location = "https://www.somedomain.com/secure_login.html"; } After login server will redirect me to another page (let's say, Page2), and I want to do some work with it ("POST"s and "GET"s). As I understand, when doing "POST" to Page2, I should somehow specify these cookies in HttpRequest. Am I right? If yes, how should I do that? If there is any example, I'll greatly appreciate it! Kosta. Re: Cookies in Winsock - How? Joaquín M López Muñoz5-Mar-02 8:56 Joaquín M López Muñoz 5-Mar-02 8:56  Are you using raw Winsock (sockets) or rather Wininet? If the latter, <a href="http://msdn.microsoft.com/library/default.asp?url=/library/en-us/vcmfc98/html/_mfc_cinternetsession.3a3a.setcookie.asp">CInternetSession::SetCookie</a> might just be what you're after. Joaquín M López Muñoz Telefónica, Investigación y Desarrollo Re: Cookies in Winsock - How? 5-Mar-02 9:15 5-Mar-02 9:15  Thanks! I'll try it! Kosta. Re: Cookies in Winsock - How? 5-Mar-02 9:20 5-Mar-02 9:20  There are 3 parameters: URL, name, data. As I understand, for cookie "uid" name is "uid", data is "somename", and what should I do for path and domain? If path is "/", and domain is ".somedomain.com", should I specify URL as "somedomain.com" or "www.somedomain.com" or somehow else? Kosta. Re: Cookies in Winsock - How? Joaquín M López Muñoz5-Mar-02 9:39 Joaquín M López Muñoz 5-Mar-02 9:39  I don't know, I'm no cookie expert. Maybe this article is of some help. Please tell us back when you find out. Joaquín M López Muñoz Telefónica, Investigación y Desarrollo Services and Window Station 5-Mar-02 8:14 5-Mar-02 8:14  Hi, Is it possible to move process from one window station to another? Here is the problem. I have service, which launches GUI application before any user logs into system. So, this GUI App works within its own window station. After user logs in I want to display the window of application on his desktop. How it can be done? I cannot change the GUI application, but I can change the service, which starts this application. Thanks, Olley Pospyelov Re: Services and Window Station Tomasz Sowinski5-Mar-02 8:22 Tomasz Sowinski 5-Mar-02 8:22  Check KB article Q173687 Tomasz Sowinski -- http://www.shooltz.com Re: Services and Window Station 5-Mar-02 8:45 5-Mar-02 8:45  This article tels how to get access to desctop of interactive user. In my case, when I start GUI application as child process there is no interactive user yet. May I somehow transfer the existing process to "winsta0"? Olley Pospyelov Re: Services and Window Station Tomasz Sowinski5-Mar-02 8:49 Tomasz Sowinski 5-Mar-02 8:49  The article mentions the API function called SetProcessWindowStation. Did you dig deeper into docs? Tomasz Sowinski -- http://www.shooltz.com Re: Services and Window Station 5-Mar-02 9:15 5-Mar-02 9:15  Yes I did;) May be I get it wrong. SetProcessWindowStation and SetThreadDesktop do all changes for calling process/thread, which is my service. What I need is to change window station for the process, which had been launched by my service earlier. The sequence I want to have: 0. OS loaded 1. My service started. 2. Service launched gui_app.exe 3. User logged in. 4. User interface of gui_app.exe appears on user's desktop. Olley Pospyelov
