I am using CRichEditCtrl in a dialog. I want to have auto wrapping off and paragraph justification as center or right. To turn off auto wrap i used SetTargetDevice which worked fine but the justification changed to left automatically. I tried to use SetParaFormat after setting the SetTargetDevice but unable to make the justification center or right when auto wrap is off.

I have a 3x3 array which is filled up of random numbers, the limit being set by the user. So if the user chooses 3, the array will be filled up of 1s, 2s and 3s randomly. That bit is fine.
So when I display the array I use:
Console.WriteLine("The values in the 2 dimensional array are: ");
foreach (int number in twoDimensional)
Console.Write(number.ToString() + " ");
The output will then be 3 3 2 1 3 1 2 3 3. Is there a way I can display it like:
3 3 2
1 3 1
2 3 3?
I'm trying to write a short program that takes the input from a user and trims any leading/trailing white space, and then checks how many words are in the string. Problem is, I'm only allowed to use stdio.h and stdlib.h. How can I accomplish this? Also, how would I check if any of the characters which were entered aren't either a number, letter, or '-'?

Is this how you do it? I keep getting an error like Cannot implicitly convert type 'type' to 'type.
I heard that you can't use it with express, but that doesn't seem right... Can you use it with Codeblocks, at least? I just hate the Qt Creator IDE. I don't like the UI... all I want to do is code Qt. I don't care much for the GUI editors.

I don`t known how to convert IP to hex .
In this link [URL] .... . I see hex IP : Hex IP 0x462a1779
I want to convert IP "70.42.23.121" to "0x462a1779"
Code:
#include <winsock.h>
#include <windows.h>
#include <stdio.h>
UINT32 ip_to_hex(UINT32 ip_add) {
UINT32 ip_hex;
//code convert ip to hex
return ip_hex;

And this is result : 7b 1e 80 and a , not 0a
Further i think we must separate each octect by a (dot) . , Then convert decimal to hex.
In a C++ project, I need to call a C# created COM object (as a .dll)
Is there a way to use such a COM object without having it be registered in the registry?
The C# COM dll is just a "go between" our C++ code and a .NET library, there's no "COM contract" of any kind, the COM interfaces change each version. The fact it's COM and needs registration is annoying because it makes it hard to have multiple versions of our software installed (needed under some circumstances) and running at the same time.
I'd like a way to not have any registration at all. And just be able to do a LoadLibrary("c:TheRightPathcom.dll") of the right dll and then get going from there.

I have a C++ app that uses OpenCV. Currently i am statically linking the OpenCV libs into my app. This is adding an extra overhead of 6+ MB.
i would like to remove some of the features that i am not using in OpenCV. The features am using are,
Capture frames from Webcam.
Face detection.
Image formats (JPEG, PNG).
Image rotation & resizing.
Is it possible to remove other features and trim down the libs?
My C++ app is developed in Visual Studio 2012.
Is there any chance to use CSplitButton in VC6 ?
I had tried to use something appropriate founded on CP, but they are using DrawItem, and I had problems with windows style, and I had tried to make myself one, overriding OnPaint, but I front with flickering (I put the sample below)... so, I wonder if I could get (from somewhere) CSplitButton and add to my project ... if you say that I could, can you provide me the CSplitButton source code ? I mean, only .cpp implementation file ...

I have an assignment where I need to go through all the files in a folder. For each file I need to know each unique file extension, how many files for each unique file extension, and the total size for each unique file extension. I have to be able to sort through this using either the file extension or the total size of the file extension. The first thing I thought of using was a map. This will keep track of each unique file extension and the amount of times that file extension was found. How do I now associate the total size of the file extension to my map? So for example I need the output to be something like this:
Using file extension for sort
.cpp : 1 : 3400
.exe : 3 : 3455600
.mp4 : 25 : 200000404
Using total file extension size for sort
.mp4 : 25 : 200000404
.exe : 3 : 3455600
.cpp : 1 : 3400

I got a program from somebody. He had its initialization to run his program but never bothered to save the data for later use. Now I wanted to add the New, Open, Save, and Close to it, so I add OnNewDocument ahead of his program. It crashed every time I ran it.
Shall I include his initialization in the OnNewDocument? If I can not separate the initialization part from his code, e.g., they come in as dll, what shall do?
Is it possible to create an app that can be saved on my desktop that can be used with an excel file that is saved on my desktop? I have opened VS 2010 and I have created a form design that has a button for every sheet name in my excel file. All of the sheet names are hidden with the exception of one. When a button is pressed on the c# form, I would like for that sheet to be shown in excel. Then once the updates have been made to that sheet in excel, I want a button to be at the top of the excel worksheet that will hide that worksheet again and return to the form c# form...can that be done?

View 3 Replies View RelatedMy question contains two projects that are under the same solution.
Project_1: I have created a dll where I use inside the project, OLE Db Template. In the project, I use this code.
class MyClass {
public:
LONG _value1;
SHORT_value2;
BEGIN_COLUMN_MAP(Accessor)
[Code] .....
Project_2: Is a project testing the Project_1.
- I want to call one of the exported functions.
- In Linker/Addional Dependencies, I have added the .lib
- In Linker/Additional Libray Directories, I have added the directory where is the lib.
- In C/C++/General/Additional Include Directories, I have added the directory on project 1. I did that because I want to #include a header in Project_1. But, when I do that, I get:
Error1error C3646: 'COLUMN_ENTRY' : unknown override specifier
Error2error C2059: syntax error : 'constant'
Error3error C3646: 'COLUMN_ENTRY' : unknown override specifier
I have done it several time with other projects, but the first time with OLE DB Template. atl90.dll is registered.
I wrote a routine in one C++ file and I decided to break it up into some smaller more manageable C++ files. When I copied the variables out of the first one and into the new smaller file (same solution), everything compiles fine but I get a ton of linker errors saying the variables have already been defined in another (the previous) file. Using Visual Studio 2008.
