If I don't assign the icon to my executable file (f.e. it's a DOS application), or I have some unknown extension in the file, Windows Explorer assigns the icon to this file.
Is there a way to somehow get this icon? Either from the registry or by any other means.
Is it possible with C# to get the default program for an extension? I've already done some research for it, but the only thing I've found out is a way to make my program the default program for an extension. So I my question is, is it possible to use anything similar to check if there is already an default program for an specific extension and which program is it?
View 2 Replies View RelatedI have a MFC dialog project, I move all the icons including the IDR_MAINFRAME icon into a resource-only DLL, so there is no icon embedded in the executable file. In the dialog initialization, the dialog loads the icons using LoadIcon(hResdll, MAKEINTRESOURCE(IDI_MYICON))). The icons shows correctly on the dialog.
But in the Windows Explorer, the icon of the .exe file is not the icon of IDR_MAINFRAME, I check the resource file in the resource-only dll project, the ID number of the IDR_MAINFRAME is the lowest one of all icon ID numbers. I also try
Code:
SetClassLongPtr(m_hWnd, GCLP_HICON, (LONG)LoadIcon(hResdll, MAKEINTRESOURCE(IDR_MAINFRAME)));
But it doesn't work. The IDR_MAINFRAME icon doesn't show in the Explorer window, the system provides a default icon for the .exe file.
tell me the EASIEST way to create a button with an image on it.
I am not interested in using the owner draw property with CBitmapButton and then have to create a whole lot of bitmaps for all the different button states.
There must be a way to simply create an ordinary button which displays an image rather than or as well as a caption....?
If I drop this regular dll project and create a new MFC extension dll project, it will involve too much work. I wonder if there is relatively easier way to convert an existing regular dll project to a MFC extension dll project? BTW, how can I tell a MFC extension dll project from a regular dll project?
View 1 Replies View RelatedI'm developing a software for Windows using MSVC 2010. My employer sent me 2 png files: 16x16 and 32x32 for the icons.
What I would like to do is to use them as a MSVC icon resource and don't use any code hacks. In the past all I had was an ico file and I just included it in the resource (rc) file for Visual Studio and that was it.
Now my question is: how do I make one ico file out of those 2 png files that will be accepted by MSVC? Is there a tool (preferably free) for it or some online service?
I have created a Namespace Extension (I hope so) by creating a ATL Project with MFC support as dll in Visual Studio 2010.
Now I have a Implementation of IShellFolder:
Code:
// ILCShellFolder.h: Deklaration von CILCShellFolder
#pragma once
#include "resource.h" // Hauptsymbole
#include "NewNSE_i.h"
#if defined(_WIN32_WCE) && !defined(_CE_DCOM) && !defined(_CE_ALLOW_SINGLE_THREADED_OBJECTS_IN_MTA)

Not any of those IShellFolder Methods is being called... When I attach the explorer.exe process (which I know I can use to debug on other projects, just in case to exclude errors) it tells me that the DLL is not loaded by the explorer.exe process.
I'm digging an old project and i can't switch to a newer visual studio.
I want to plot float data array during debug.
I know some IDE's have such option. There is a separate window in which we can plot data.
Can I write such plugin for Visual Studio 6.0 using visual studio SDK?
Does it support 6.0 version?
how to change the mouse tracking icon during runtime. I wish to emulate the Microsoft Paint app behavior with respect, for example, to click on a toolbar button such as the 'Fill With Color' bucket and have the mouse pointer icon change to a little bucket. I wish to do this in an MFC SDI app.
Here's a bit of code that does nothing that I can tell, although it compiles and runs. (m_hIcon2 is a member HANDLE, IDI_FLOODFILL is an existing icon in the app resources). I have come across numerous other examples that do not work and/or will not compile using VS 2010 Win7(64).
Code:
void CMainFrame::SetNewIcon() {
m_hIcon2 = LoadIcon(AfxGetInstanceHandle(), MAKEINTRESOURCE(IDI_FLOODFILL));
SetIcon(m_hIcon2, FALSE);

Where in registry the Explorer stores tray icons visibility settings? (Always show, show only notifications, or always hide.)
I know that Microsoft doesn't want us to change these from a program, which may be OK for a home computer, but it becomes a major pain in the ___ for an enterprise environment (as there seems to be no GPO to do this either.) I've seen couple commercial products that were able to do this, so I'm sure there's a "hack" somewhere...
I made a dialog to have a customizable msgbox. (custom icon, custom caption on buttons). This is how I try to display an icon on the dialog but it is not working.
HICON hIcon = LoadIcon(NULL, IDI_QUESTION);
HWND hImageCtl = GetDlgItem(hDlg, IDC_STATIC);
::SendMessage(hImageCtl, STM_SETIMAGE, IMAGE_ICON, (LPARAM)hIcon);
//SendDlgItemMessage(hDlg, IDC_STATIC, STM_SETICON, (WPARAM) hIcon, 0);
i can write a mfc program to make a Thumbnail view with image but can not this when change image with CDialogBox.

Is it possible to define and write your own file extension. if so is it an easy process or a complex waste of time. All I want to do is define a source file for a programming language I write.
View 3 Replies View RelatedThe code below is used to return a file path.
private string BrowseJournalFile(string startRelativePath)
{
string str = "Journal files (*.log)|*.log|All files (*.*)|*.*";
return PathTools.BrowseFile(startRelativePath, str, this.RootPath);
}
So once I click browse I get something like "E:New Files" But there is this .log file in this folder which I want to automatically store in this path.
Right now I have to click on this .log file and then select open. Is there a way I can directly load the file.I have been trying to use the FileStream but no luck.
I am trying to write a function that determine if a file in a directory is of a gif/bmp/png/jpg extension. Right now I think I have correctly written my code all the way up to listing the files in the directory and opening them in binary mode.
Now, I am struggling with figuring out how to determine what extension the image is. Right now i am just focusing on writing my "bool isGif();" function... To determine if a file is a .gif extension using binary, the first 6 bytes of the file will contain either GIF87a or GIF89a.So, to do this I would read the first six bytes of the file using the function below, correct?
fin.read((char *) &a_file, 6)
Then, once I read in the first six bytes how would I conditionally compare it to determine if it is a .gif? Would I just use
if(fin == "GIF87a II GIF89a) {
\do something here
}
Because that doesn't seem to be working...
So I'm making setTimeout and setInterval functions.
I have this remember function (that is part of Timing class) which takes a function pointer and a void pointer, which are remembered in that object.
Another (timing) function of that object is called in every loop of the program and when specific time passes that function calls the remembered function whit the remembered void pointer as argument.
The problem is that the functions that need to be called require unknown multiple parameters, so what I need to do is make a new class that will store the needed arguments. I make the function that needs to be called and that storage object and pass pointers to them to my remember function, when the remembered function is called it stores the data from storage object in new variables and dose it's thing.
I have a problem with an extension DLL that has an exported function. The function is being exported ok, it is called by a Windows service. The Windows service is using the exported function, and everything works. I am trying to create a file with:
ofstream file;
file.open("C:dir ofile", ios:ut);
file << "text";
But nothing happnes however. There are no errors, the file is just not created. Also, if i try to call MessageBox() in the exported function, nothing happens as well . I have a .h file which exports the function with __declspec(dllexport) DWORD WINAPI functionName(), and also a .cpp file with the function definition. There is no main().
I compiled the source code of QT5.1 to work with Visual Studio 2010.
But it always start off with a win32 project, so that I need to change the settings every time.
How do I kick start with a x64 project by default?
For an assignment I have to write a program which basically converts 8 bit binary numbers to ASCII and outputs the assembled text. Here's the catch:
The 8-bit binary numbers are provided by some external file (which only contains 8 bit binary numbers); the name and hence length is not known. The external file is called with a pointer upon execution
(./"conversion program" < external_file.in).
I'm getting the 8 bits as a string, calculate/convert decimals, output char type. HOW do I know when to stop the loop? If I just pick an insanely high number I get random stuff at the end; no boundaries obviousely lead to an infinite loop. Can I determine the lenght of this random ext file somehow nonetheless?
Is it possible to create a vector which dynamically adjusts itself until there are no more strings = end of the file?
The assignment is to open an encrypted file, count the occurrence of each alphabetic character in the file. find the highest occurring letter and use that to find the shift, then apply the sift to the file in order to decipher and then print out the deciphered txt.
#include <fstream>
#include <iostream>
#include <string>
using namespace std;
int main(){
string word;
ifstream txt;
int arr[26] = { 0 };

I'm overriding OnNcPaint to do my own caption painting (in a dialog box). If I call "Default" before I do my painting, the default caption and borders remain (as if I'm not painting at all). If I comment out my call to "Default", my caption looks great, but I get no menu bar (I have a menu on the dialog). If I call "DrawMenu" before or after painting, the dialog is all screwed up (and there is no painting in the nonclient area).
I'm running VS2012, on Windows 7.
I needed to change Default Text attributes (font and color) . So I wrote following code , UnicodeTextOut function. I called this function once in each 55ms to update the display screen. but I observed that my Screen used to become grey like a crash after sometime . If I use Minimize an Maximize window , the screen was restoring back for some time.
When I thought over the code , I got my mistake that CreateFont initialization should be done once in the program and probably outside the function.
void UnicodeTextOut(int x, int y, CString s, UINT justify,int GreyScaleFlag) {
HFONT hFontUnicode;
HFONT hfOld ;
hFontUnicode = CreateFont(16, 0, 0, 0, 0 , 0, 0, 0, 0, 0, 0, 0, 0, _T("Aerial"));
[Code] ....
Then I shifted the line hFontUnicode = CreateFont(16, 0, 0, 0, 0 , 0, 0, 0, 0, 0, 0, 0, 0, _T("Aerial")); in my screen class constructor and made hFontUnicode global .
This solved my problem as expected. Why a system crash after certain no of CreateFont calls ?
There was an "impovement" since Windows 7 in algorithm for selecting the initial directory, which is described here OPENFILENAME structure. Briefly:
Windows 7:
If lpstrInitialDir has the same value as was passed the first time the application used an Open or Save As dialog box, the path most recently selected by the user is used as the initial directory. Otherwise, if lpstrFile contains a path, that path is the initial directory.
Otherwise, if lpstrInitialDir is not NULL, it specifies the initial directory. If lpstrInitialDir is NULL and the current directory contains any files of the specified filter types, the initial directory is the current directory. Otherwise, the initial directory is the personal files directory of the current user. Otherwise, the initial directory is the Desktop folder.
The problem that this behavior is not what users of my program expect. Another constraint is that I need to use old CFileDialog dialog, not Common File Dialogs. I've tried to use advises described on StackOverflow and on MSDN. This solution by EllisMiller works perfectly:
Specifying a full path (including filename) in lpstrFile. The filename of course shows up in the filename box which is annoying. I ended up using a filename of "." and adding a bit of code to clear the filename combobox once the dialog is open.
BUT I can't figure how to clear the filename combobox. I've tried to add hook procedure, enumerate windows and clear text, but this didn't work for me. So, my question is: how can I clear text in the filename combobox of CFileDialog?

I am trying to load an icon I created for my program. Relevant code is below:
Code:
//resource.h
#define IDR_MYMENU 103
#define IDR_MYICON 201
#define ID_HELP_NOTICE 40001
#define ID_HELP_ERROR 40002
#define ID_FILE_EXIT 40003
[Code] ....
For some reason, the icon fails to load. I ran a breakpoint at the line for the hIconSm and got this error for the variable:
Code: CXX0030: Error: expression cannot be evaluated
The icon image is in the source folder and was compiled via ImageMagick. Google is not giving me any info regarding the error and the icon combined.
