You need to understand the use of all the windows messages which all have names beginning WM_, and are documented in MSDN. The links I gave you earlier will lead you to some of them. You can also look at the SendInput function[^] which may make it easier to achieve what you want.
Sorry, this site does not provide a service like this. You need to use your debugger to identify where the crash occurs and why. You can then come back here with the details, and people will try to help you.
I'm not sure that this is anything to do with managed C++/CLI, however ...
If you have a problem with some code that you downloaded from the internet, then you need to go back and talk to the person or people who provided it. But something called workingbutcrap is not very inspiring. And if you have issues with an article here on CodeProject then you should use the forum at the end of the article.
I'm facing the following strange problem using MFC Grid Control (by Chris Maunder) in my VS2010 MFC application:
I've included the CGridCtrl control in a dialog in order to let the user to edit data. It works fine but sometime when I open the dialog the cells content is not displayed but it's covered by the cell background color.
Unfortunately I can't solve the problem because it only happens randomly. I tried to call Invalidate() to both the CGridCtrl control and the dialog but it doesn't solve.
I want to save the ASCII characters, in this case i started with the "☺" when someone press alt+1.
I dont know how to save that type of characters in the txt. What can i do?
Ive searched like a month about this, in all kind of forums, asking my teachers or people who knows and nobody can answer me this.
A possible solution was to make all again and use HOOK functions and some others like: WH_KEYBOARD_LL. Well... i dont know how to use any of that functions, so its a big problem.
First of all if you want handle characters that are out of standard printable set, and could be filtered by text handling, open the file as binary:
FILE *txt = fopen("Experimento.txt", "ab+");
In this case you have to manually handle end of line adding "\r\n" at end of each line isteade of the simple "\n", but you are free to store the whole set untouched.
Anyway even using standard text file opening there could be a couple of issues that you have to deal with. Just to be sure that the correct code has been saved in the output file open it in a binary editor and verify that the code 0x01 has been stored in the file, if it is not there you can try to open the file in binary mode, as reported above, or you can use putc instead of fprintf:
But if the file is correct and 0x01 is in but you cannot visualize it the problem is a different one, if you can't show it in a console window or in a text editor the problem is that the ascii code you expect is not in the codepage used on your system. In this case the things get somewhat harder...
I am trying the display the transparent ".png" image on the button it is working fine if i have the proper resource file but the situation is like that i have to get the image from a file and Load it on the button how do i do it please any kindly help me.
This array shows music times: 1 - 1/2 - 1/4 - 1/8 and so on.
I think it should be written by recursive function, because I couldn't do it by while and for loop.
Now, I need all sorted figures that sum of them are equal 1. For example:
1/2 - 1/2
1/2 - 1/4 - 1/4
1/4 - 1/2 - 1/4
1/4 - 1/4 - 1/2
1/4 - 1/4 - 1/4 - 1/4
1/8 - 1/2 - 1/4 - 1/8
1/8 - 1/2 - 1/8 - 1/4
1/8 - 1/2 - 1/8 - 1/8 - 1/8
Of course, number of figures will be too many more if we add 1/16 and 1/32 and ... .
I can print them in a web page(response.write) or in a c console; it's not important. But the algorithm should be as simple as possible.
Thank you all.
HackerMan has a message in form of digits but he wants to decode the message so that if enemies gets hold of the message they will not be completely able to decode the message.
Since the message consists only of number, So decoding involves reversing the number. The first digit becomes last and vice versa. For example, if there is 1245 in the code, it becomes 5421 now.
Note : All the leading zeros are omitted. That means if the number ends with a zero, the zero is lost by reversing (e.g. 1200 gives 21).
HackerMan is further thinking of complicating the process and he needs your help. Your task is to add the numbers after reversing and output the result after reversing the sum.
The input consists of N cases. The first line of the input contains only positive integer N. Then follow the cases. Each case consists of exactly one line with two positive integers separated by space. These are the reversed numbers you are to add.
For each case, print exactly one line containing only one integer - the reversed sum of two reversed numbers. Omit any leading zeros in the output.
The value of N will be less than 10000.
The value of digits will be less than 5000.
When I run the command line app I can debug through the cpp dll into the C# dll but when I return from the cpp dll I get error on returning to the debug commanline app.
I get error:
An unhandled exception of type 'System.AccessViolationException' occurred in mscorlib.dll
Additional information: Attempted to read or write protected memory. This is often an indication that other memory is corrupt.
but i keep getting errors from
control.cpp, output.cpp, tessedit.cpp and tesseractemginewrapper.cpp
the error are all the same stating error C1010: unexpected end of file while looking for precompiled header. did you forget to add '#StdAfx.h' to your source?
as i am completely new i tried with/without the StdAfx.h and StdAfx.cpp which was there when i first created the project.
The message is telling you exactly what is wrong. Your project is set to use precompiled headers, but you forgot to include StdAfx.h in your source code. Each source file (.cpp file) should include the following line at the top:
When this event gets activated, does the event args structure get cloned for each object instance that subscribes to the event, or is there a single instance of the event object with each event handler getting a managed pointer to the same object?
What I'm really getting to is whether the large array gets cloned for each event handler. I'm guessing no.
Many thanks in advance for any pointers (no pun intended...)
The only other method to count 1 to 1000 is using recursion. According to C language, j has ‘1’as its value at the beginning. When 1 <= j < 1000, &main + (&exit - &main)*(j/1000) always evaluated to &main, which is the memory address of main. (&main)(j+1) is the next iteration we want to get, which would print ‘2’ on the screen, etc. The stop condition of this recursion is that When j hits 1000, &main + (&exit - &main)*(j/1000) evaluates to &exit, which will elegantly exit this process, and has the error code 1001 returned to the operating system.
is evaluated each time thus: &exit - &main is the offset from the start of main to the start of exit j/1000 will evaluate to zero for all vaules of j less than 1000
Multiplying those two values together gives zero if j is less than 1000.
Add that to &main (the address of main) and you get the same address, so main gets called with the parameter value j+1.
This continues until the value of j reaches 1000 at which time: j/1000 results in the value 1
That is multiplied by the offset of exit which returns that offset.
Add that value to main and the next call will go to exit rather than main.
I have an application developed in non-CLR C++ (unmanaged) in VS2003 (or earlier) but working with VS2005 after some converting. Note that I didn’t do that converting.
My employer decided to update the code to CLR VS2010 for easier maintenance. I am a C# programmer and haven’t done C++ for a while and not within VS so I’m not the most skilled in this task.
I’ve set it to CLR and corrected the errors and most of the warnings, but I’m having a problem with some image resources in the Form1.resX file (took me a while to even figure out that the resources were IN that .resx file I can see them in there and the Form [Design] editor can see the resource and paints the image as a background for its tab:
The resX file is version 1.3 of the schema or so it says rather than the 2.0 that a newly created windows forms application has but seems OK otherwise.
Microsoft ResX Schema
The resource looks something like this:
So the call seems correctly formed and it’s good enough for the design editor inside Visual Studio. But when you run it you get an error:
An unhandled exception of type
'System.Resources.MissingManifestResourceException' occurred in mscorlib.dll
Additional information: Could not find any resources appropriate for the specified culture or the neutral culture. Make sure "PRG.Form1.resources" was correctly embedded or linked into assembly "PRG" at compile time, or that all the satellite assemblies required are loadable and fully signed.
As you can see, the culture is neutral so the fact that there is no culture in the call seems right. I tried deleting the culture tag from the resource entirely but that had no effect. I don’t know quite what the program wants me to do in order to get this image to come up in the running application. I wondered if anyone has an idea of what I might try next.
Just wanted to add the line that connects the resource file to the form because i'm thinking that could be a problem but I don't know quite how.
