Using mfc I have an application where I'm not allowed to use a mouse and alt+tab will be regularly used. Using alt+tab to come back to my application kills the focus in the view. Once my application comes back to the foreground how can I set the view as the focus?
View 3 RepliesFor the past couple days I've been making small improvements on a program I made to keep track of a battle count while playing a game. Mainly to reduce the chore of keeping track yourself while you're playing. But it still becomes a hassle to switch back and forth between the program and your game and I was hoping to be able to set focus to the game after the BattleCount method is called.
Currently I am importing a DLL that somebody recommended I use to make a ActiveProcess method that accepts a integer as a parameter which would set the PID but it doesn't seem to be working. The two methods are as follows.
private void countDownClick(object sender, RoutedEventArgs e) {
//Calls a method within my class that subtracts and adds battle values.
counter.CalculateBattles();
//These two change text on my WPF forms with accessor values from my class.
battlesWonText.Text = counter.BattlesWon.ToString();
battlesLeftText.Text = counter.BattlesLeft.ToString();
[Code] ....
This is the C++ code they told me to use to set focus to another application using a PID.
[DllImport("user32.dll")]
static extern bool SetWindowPos(IntPtr hWnd, IntPtr hWndInsertAfter, int X, int Y, int cx, int cy, uint uFlags);
const UInt32 SWP_NOSIZE = 0x0001;
const UInt32 SWP_NOMOVE = 0x0002;
const UInt32 SWP_SHOWWINDOW = 0x0040;
[Code] ....
I'm simply trying to figure out how to set focus to a foreign program using their PID and a button click event in WPF. I'm using Visual Studio 2012 on Windows 7.
I want to read the bar code using USB scanner without having the focus on text box using WPF. I have searched around online but not found related answers, I think it is the correct place to post my question.

this.tB2.Click += new System.EventHandler(tB2_Click);
private void tB2_Click(object sender, System.EventArgs e) {
tB2.SelectAll();
}
What would be the simplest way to do the same for all textboxes on the form, preferably on both click and enter events.
I have MDI form which contains mutliple tabs and each tab has its own child form . When user presses ALT TAB from the from to other application its fine but when users presses ALT TAB back to my application it should keep focus on child form last time it was selected.
View 1 Replies View RelatedI have a strange problem in using C code. I want to move focus from one item to another in a keypress event (like keydown)in loop. But it move directly to the last item
Details: In the code segment, I am generating keypress event explicitly from code and want to move focus for number of items inside loop. Loop is working properly, but output is also generated after completion of loop and focus is directly coming on last item in list not showing intermediate movements. Voice output using espeak is generated correctly in each iteration.
Tryouts: I have tried to call a dilog box which take yes/no event by Btn press,that works fine. That means event generation in code is giving problem, it needs h/w intervention for keypress (As I understood)..
I want to highlight selected text in a wpf textbox while the textbox is not focused. In my application, my textbox never gets focus, and every key input is done manually. I was wondering if there is a way to highlight the selected text when the textbox is not focused?

What I'm trying to do is get the selected folder value put into my dirlocation var.
Code:
private void dirLocation_Click(object sender, EventArgs e) {
FolderBrowserDialog fdb = new FolderBrowserDialog();
fdb.Description ="Please choose the directory your .rlt files are located in";

}
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 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

#include <iostream>

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?

My 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.

The problem is that the message appears inappropriately, both when no previous document has been loaded or should exist, and even after File / New has been envoked. I have attached a small demo program to demo the problem. Inspecting the SpVwTrDoc.cpp NewDocument and OnOpenDocument, and elsewhere, you will see that using SetModifiedFlag(FALSE); has no effect.
