General and Desktop

ummm tnx but do you have article about of ? how can i learn ?

Hi RS, Just an FYI, use code tag while writing code in post for better readability. (right most symbol on post area) @//JustAnExample processMemUsedLabel->setTextFormat(Qt::RichText); QString testStr = QString(“Used Mem”) + QString(QChar(’%’)); processMemUsedLabel->setText(testStr);@

I'm sorry, I must have totally misread your post.

I am using both Windows 7 and Fedora Core.

Thanks for the replies you guys.. I just wanted a very simple encryption (XOR). Just to try it out and see if I could do it because, this (mind you) is my first time working with encryption at all in QT.

I am not actually using a timer :) I wish this was the case though! I have an while loop like so: @ void newThread::run() while (t_thread){ // inifinite loop ... // do things ... // do things msleep(18); } } @ I have calculated that it takes about 2 mS to execute the code that I am doing using the Qt mS timer. On application close, I just toggle the boolean and wait for the thread to finish cleanly before I terminate. my background has been C all through school mainly for mp's as well as the linux OS, so the object oriented programming in C++/Qt is new to me this year and i'm still learning "its ways" :) And from what Volker has stated before, does Qt allocate memory differently that what the underlying c++ would do for using standard c++ types (doubles, ints, ect.)? I can understand if the memory was being tampered with, but the memory location of the single double should be able to be read from anywhere, anytime, from whomever if it does indeed exist. I might be wrong since I am not sure what Qt does in the background or how it deals with it.

I have the same problem with QSharedPointers but soon realized that I was doing this wrong. I have the following situation: There is a Provider object that handles all communication between my program and a remote server. It has a List object which contains several Type objects and is given to other objects. The list is an abstraction to hide the Provider object, meaning I want to use the List object to add/edit/remove the Type objects. Because the Type objects are given to various other objects that are interested (ListViews for example), it is needed to use a QSharedPointer to check if it is being used and if the Type object is still valid. When the Type object itself is changed, it will call a function of the List object which calls a function of the Provider object which will send an command to the server. My first thought was to use a QSharedPointer in the 'changed' functions but realized it would be better to send a plain pointer and let the 'changed' functions determine the QSharedPointer attached to the object. (This was possible because the List object actually creates the Type objects by using new). This way, you don't create a new QSharedPointer to the same object nor do you need a global map but you do use some kind of map functionality by looking up your QSharedPointer. In short: When you want to pass the 'this' pointer as a QSharedPointer, you first pass it on as a plain pointer and then determine the QSharedPointer used to create the object. If this is not possible in your situation, I think you have to change your program or reconsider if using QSharedPointers is the correct way.

If you need not crossplatform solution u can: @ //add to header file extern "C" IMAGE_DOS_HEADER __ImageBase; #define THIS_MODULE_HINSTANCE reinterpret_cast<HINSTANCE>(&__ImageBase) //Then ::GetModuleFileName(THIS_MODULE_HINSTANCE, szBuffer, MAX_PATH) @ "token from rsdn.ru":http://www.rsdn.ru/forum/winapi/261670.aspx

Thanks

You really lost me. If you want file encryption, I think there are better ways. Good luck with your project though!

Hi stima_ua, This is exactly what i was looking for. Thanks a lot :) Regards Soumitra. Edit: Finally I got something that looks like this :- !http://img138.imageshack.us/img138/583/captureecb.png(exapandCollapse)!

I reinstall window xp,and it works!

[quote author="Andre" date="1336039264"]Could you tell us, what system you're using?[/quote] its windows 7

Ok then, thanks ;)

Well, you have to see that - although I wrote that patch - I'm quite a Qt newbie. So for me it is more trouble, since I have to read more code to make sure I do it right. Also none of my "Qt dev mentors" asked for this. So it is like it is, since it meets my needs, but as you know, you are invited to further improve it. ;-) (Although I wouldn't really see this as a Qt property)

The Qt resource system allows you to embed a kind of virtual filesystem within the binary. The path ":qt/etc/qt.conf" does extactly mean what you're suspecting: QLibraryInfo first looks inside the embedded data if the "virtual filesystem" contains a file qt.conf in the path qt/etc/qt.conf - so yes that's the path "inside the executable" the file has to be stored. Mayby this one will help you a bit on this topic: "Qt Resource System":http://qt-project.org/doc/qt-4.8/resources.html
