I am writing a program that runs in the background and controls a text editor. My program sends key sequences to the editor to open the Find and Replace dialog box of the editor (this is a dialog box customized by the editor).
So far, this method works great. The only problem I am having is that the dialog box quickly appears and disappears (since I send the key sequences + enter key as well).
So, I am trying to get a hold of the "Find and Replace" dialog box when it is created (I know for sure that the dialog is created each time when the user presses Control-F) so that I can resize it to zero. I tried to put a hook into the CreateWindowEx function, but it doesn't look like that function is called after Control-F is pressed (i.e. the "Find and Replace" dialog box is displayed).
If you have a thought on how this could be done, please kindly let me know.
Thank you very much.

In whitch module did you hook CreateWindowEx? I guess that the editor doesn't directly call that to create the find dialog, it probably uses DialogBox[^] or CreateDialog[^] (or one of their friends, see the See also links at the bottom of the MSDN pages). These are defined in user32.dll so if i were you i'd try to hook either these (probably more complicated to fiddle with the dialog) or i'd try to hook the createwindow method in user32.dll.

Hello , my problem is this:
I have a dialog based app that used to works fine, then i added some code ,a few lines, and i forgot to put some "()" and ";" , then when i tried to compile, the compiler crashed , so i killed the Microsoft visual c++ with the task mananger and then i re started the Microsoft vc++ and i opened the same project again, i deleted the few lines added before and i compiled again, no errors messages, but when i attempt to run the app (with crtl +F5) it doesn't starts , so i try to debug the app and i get these errors messages :

Thanks in advance guys.

the first 30 or so lines are not errors. that's just VC telling you that you won't be able to debug into system DLLs. you'll see them every time you start the debugger.
the last 8 are telling you that you're trying to set a checkbox to an invalid state. check your DDX_Check calls, and make sure that the last parameter has been set to something in the range of 0 to 2.

Thanks, well i found and deleted the lines that causes the warnings, now when the debugging starts i get:

The program 'D:\Proyecto final\VC++\Calibracion2\Debug\Calibracion.exe' has exited with code 0 (0x0).
And of course when a try to run the app (.exe) the process is loaded into memory , it consumes 50% processor resourses, but never it appears on the screen, like i said above , before the first crash, it was working, and now i have the same code , and i don't touch anything else, i'm confused.

ignore those msgs, really.

Ok , but do you have any ideas of what is happening? Once i had a similar problem and i took the project from a previous backup, and i added the new lines , compile and problem solved, i'm sure that if i do the same again, the problem would be solved, but it's a lot of work to update the project from the last backup, and I'm really intrigued of wich is the cause of that kind of problems. . .

every app in Windows loads a whole bunch of DLLs from the system, in order to run. when those DLLs get loaded, the debugger looks at them to see if it can step into them or not. if not, the debugger will print a little message telling you about it. obviously, nobody outside of Microsoft can debug into the system DLLs.
it isn't a problem, really. there is nothing to worry about.
if you didn't see those messages before, maybe you were running in non-debug mode. but if you're running in debug mode, you should expect to see them every single time you start your app.

You are right, haps i didn't explain
it too well, let's forget those messages, the problem is that before i added some lines to the project, the app was running well, then i added those lines , with some mistakes and when i tried to compile the compiler crashes, so i closed the projet and opened again, i deleted the added lines (so the code is the same that before) and compiled it, no errors, but when i try to run the app (not in debug mode)it doesn't works, did i explain well?

Set a breakpoint at the beginning of the program and run it with the debugger. Single step through each line of code to find what is causing the problem. This is the only way to discover what is wrong.

Thanks man, i ran the app step by step and i realized that the problem was a "For" sentence in wich the condition was i= 100 instead of i<100, so tanks a lot.

Wish I had a £ for every time I've done that

now i use vc++ 6 to control ms word,i want a table's cell has a DiagonalDown line,

how can i set DiagonalDown line in a ms word table's cell
thanks a lot

Hi,
(my first post on CodeProject )
I am unable to use GetPtrEx and GetPtrEx2 function versions.
I get Unhandled exception.
Please tell me why...
class CTest
{
private:
char *a;
public:
CTest(int n=10)
{
a= new char[10];
a="george";
}
virtual ~CTest()
{
}
char * GetPtr()
{
return a;
}
void GetPtrEx(char **ptOut)
{
ptOut=&a;
}
void GetPtrEx2(char *ptOut)
{
ptOut=a;
}
};
int _tmain(int argc, _TCHAR* argv[])
{
CTest obj;
char *rx=NULL;
obj.GetPtrEx(&rx);
cout<<"sir="<
|
|
|
|
|
The parameters need to be passed as references (e.g., void GetPtrEx2(char*& ptOut)).
As it is, you're making a local copy of the parameter in the function bodies and are manipulating that local copy. The variable in your main function is unchanged after calling GetPtrEx because only the local copy inside the accessor was modified.
In order to have changes inside the accessor preserved and made available to the caller, the parameters must be passed as references. In effect, this passes the address of the original variable, rather than making a local copy. Changes made in the accessor will affect the original copy of the variable declared outside the accessor.
Also, in the future, use the 'code block' button above the edit window when posting code. It makes it much more readable; a lot of people here won't even respond to a message loaded with unformatted code.

|
|
CTest(int n=10)
{
a = new char[10];
a = "george";
}
This is incorrect, you are merely overwriting the pointer in a; you need to copy the string to 'a' via strcpy() or similar. Also the constructor takes a value that is never used.
void GetPtrEx(char **ptOut)
{
ptOut = &a;
}
This changes the local copy of ptOut; it should be *ptOut = a;. Similarly GetPtrEx2() does nothing useful.

my question as follow:
there're various icons on the desktop, which are system icons, app icons, icons created by right-button and so on;
why only icons created by right-button can found on the path of desktop?
thank you very much, 兄じゃん

I'm most likely not your brother, and i also am not sure what you exactly mean by your question, but not everything you see on your desktop are filesystem objects, "My Computer" for example or "My Network places" aren't filesystem objects, you won't find them if you look at the directory listing of your desktop. I hope this answers your question.

thanks, since they are not filesystem objects, how explore.exe display them.
if you setup one game, for ins, World Of Warcraft, it'll produce one icon on the desktop,
this also is not filesytem object, is this?
|
|
|
|
|
Not only filesystem objects can be displayed by the shell, maybe read this[^] for more info.
However, games usually place links to your desktop to make it easier for the user to start them, links ARE file system objects, with .lnk as extension (so these do appear in a folder listing), i believe the shell uses the file the link is referring to to give an icon to it (so for example if the link "points at" a txt file, then you will see a text file document icon, or if the link points at WOW's executable, then the link will get the icon of WOW), also, unless you dissable this feature (i think you can do that) the shell will place a small arrow icon in the corner of the bigger icon to show you it is a link at another object and not the object itself.

Sorry, i can't read what you sent there, i tried a few encodings in my browser but nothing produced anything human-readable to me, but if it is anything than english or german (or hungarian), i won't understand it anyways.

Aha, it's japanese sentence and its meaning is thanks very much!
I just am a freshman in the code-world, and need to keep up with you.

Ah, yourwelcome, glad i could give some help. Please always use english if you post anything here on this forum so everyone can understand, the more people understand your problem the more help you can expect.  And welcome to the code-world.

This is not a C++ question. However, I suspect you are talking about their visibility in Windows Explorer, which is controlled by the settings you have selected. Look at the Tools -> Options selections on the menu.
