Visual C++ :: How To Localize A Plug In DLL File
Jul 20, 2013
I have experiences to localize a few MFC executable files, first create a resource dll file then add following code in InitInstance():
Code:
BOOL CMyApp::InitInstance()
{
//Default Application Wizard code.
HINSTANCE hRes = NULL;
hRes= LoadLibrary("ResourceD.dll");
if(hRes)
AfxSetResourceHandle(hRes);
//Rest of wizard code
return CWinApp::InitInstance();
}
Now I need to localize a dll file which is an IE web browser toolbar, who could tell me how localize the dll file?

I have some strings that shows big number. I need to add commas to the big number so for example 9999999 become 9,999,999.
I need it to be localized and I know that some languages uses the char '.' instead of ',' ... How can I do it ?

I have designed a vc++ dll for a controller. I want to add usb plug and play feature inside the dll. I searched on line and came to know:
"If the project is an unmanaged C++ DLL project, then I can only create windows in an unmanaged way, i.e. the usual Win32 API way, such as adding a new dialog box as a resource, or simply using RegisterClassEx() and CreateWindowEx() to create the window yourself, then pump messages for those windows using GetMessage(), TranslateMessage() and DispatchMessage()."
how to use this concept.
I have created a separate application (in delphi 2007) that load this Dll. But I want to add this Plug and Play feature inside me dll.

I'm very new to MFC & VisualC++. I'm using MSVS2010 Pro. I am trying to write/debug a simple form that saves and restores the content of some edit controls. It seems to work as expected, except the file saves only to the Project Folder, regardless of where I browse and select to save the file.
Code:
void CMFC_FileDialogDlg::OnBnClickedbtnsave() {
this->UpdateData();
CFile f;
//Kinda Correct, Works but still saves in Project Folder
BOOL b_OpenFileDialog = FALSE;//this doesn't act as bool in CFileDialog?
[Code] ....
My only experience is a little simple VB programming in Excel, so any specific examples??? Also, rules seem to change from version to version? I have to "update" a number of undocumented programs.

I am trying to use ini file for configuring my app.
But GetPrivateProfileString is not working.
I am using Windows 7. I tried "Wow64DisableWow64FsRedirection" also.
Not only this-ATLPath::FileExists is also not working.It gives an error code 0x80070002 which means:
"system could not find the file"

I need to develop an application in VC++ that will take .WAV files as an input and identify if there is a Gun shot in that wave file. WAVE file with gunshot must be having certain paramaters like frequency, bit rate etc which I don't know right now. But is there a way in VC++ to develop a program that can recognize gunshots by comparing that .WAV file with certain parameters?

I created a new project in Qt Creator, the files included are the .Pro file, and the .Cpp file.
Qt does not recognize the headers I try to reference in the .Cpp file. I am pretty sure it's because of what I don't have in my .Pro file. What do I add to it?
.Cpp
Code:
#include <QApplication> ->No such File or Directory
#include <QPushButton> ->No such File or Directory
#include <QHBoxLayout> ->No such File or Directory
int main(int argc, char *argv[]) {
QApplication app(argc, argv);
QWidget *window = new QWidget;
[Code] ....
.Pro
Code:
SOURCES +=
MainWindow.cpp

Say, I have the "K: est del USB" folder.
Then I do the following:
Code:
SHFILEOPSTRUCT sfo = {0};
sfo.wFunc = FO_DELETE;
sfo.pFrom = L"K: est del USB";
sfo.fFlags = FOF_ALLOWUNDO |
[Code] ....
So when I run it, the SHFileOperation API shows this warning:
Are you sure you want to permanently delete this folder?
If the end-user clicks "No", SHFileOperation return 0x4c7, which I believe is ERROR_CANCELLED.
My question is, if I don't need any UI, how can I know that my file/folder will be permanently deleted vs. placed into the Recycle Bin?

I'm trying to build libglib using MSVC. libglib doesn't use dllexport - so to create usable DLLs it needs to generate a .DEF file. It does this by using a .symbols file. Here's a cut-down example:-
Code:
/* This file lists all exported symbols. It is used to generate the glib.def file used to control exports on Windows.*/
/* glib.symbols */
g_mkdir_with_parents
#ifdef G_OS_WIN32
g_file_get_contents_utf8
#endif
The following commands would produce the following files called glib.def
Code:
cl /EP glib.symbols > glib.def
produces this in glib.def:-
g_mkdir_with_parents
Code:
whereas this:-
cl /EP -DG_OS_WIN32 glib.symbols > glib.def
produces this in glib.def:-
g_mkdir_with_parents
g_file_get_contents_utf8
So this is a handy way of producing conditional .DEF files. Fortunately, this can all be built into a Visual Studio macro in my vsprops file - e.g.
Code:
<UserMacro
Name="GlibGenerateGlibDef"
Value="echo >"$(SolutionDir)glib.def" && cl /EP -DG_OS_WIN32 glib.symbols >>"$(SolutionDir)glib.def""
/>
Problem:- Although I can run the macro as a pre-build step (and it does produce conditional entries in the generated .DEF file) it DOESN'T produce the word EXPORTS at the top of the file. So the linker then fails to recognise it as a valid .DEF file.
How can I add that word EXPORTS to the top of the generated file? I tried just adding EXPORTS to the top of the symbols file but that didn't work. I also tried this variation on the macro:-
Code:
Name="GlibGenerateGlibDef"
Value="echo EXPORTS >"$(SolutionDir)glib.def" && cl /EP -DG_OS_WIN32 glib.symbols
But that didn't work either I feel sure there must be a way to do this.

I am developing a CFormView MFC app. When I go to click something on the menu, it takes awhile before the event happens. The project is build optimized in release mode. I have 3 additional threads and I thought they might be blocking the internal MFC framework stuff, but I use the Sleep() call in each thread to yield to the MFC main app.

I have an MDI application using different menus depending on the current document template in use.
I need to show the top-level File Menu from the IDR_MAINFRAME window when a command is sent from the active document.
I would like to application to deactivate the active child window and then show the File menu as if the alt-F key was pressed from the keyboard.
I have tried CMenu *pMenu=AfxGetMainWnd()->GetMenu();
but this does not display the menu at all.

I have written code that saves a matrix to a utf-8 file. This code works just fine when invoked from a win32 console app, but if I attempt to use the exact same code by invoking it within a SDI Doc/View Serialize(CArchive& ar), if(ar.IsStoring), it fails, but in a somewhat unusual manner. Namely, the file shows up in the designated directory, but it is an empty file (0 bytes), and the 'Unable to open file' message is seen in Debug config. Note that both the win32 console app and the SDI app are both using a Unicode character set, however, only the SDI app uses the method inside a Serialize(CArchive& ar) method, whereas the win32 console app evokes the save method directly from within _tmain. Why this seemingly illogical disparity occurs.
Here's the template code I have used in innumerable applications to save matrices to a disk file.
Code:
namespace TNT {
// saves a TNT double matrix, discriminating between real and complex matrices by virtue of the respective file markers, 'MATCALC94R' and 'MATCALC94C'.
template <class T>
void SaveRealBMatrix(const Matrix<T> &M, string sfilename) {
_RPT0(0, "SaveRealBMatrix:
");
_RPT1(0, "sfilename =: |%s|
[Code] ....
Here's the code from the SDI document Serialize(CArchive& ar) that fails as described above. Note that m_M is a class member TNT::Matrix<double> m_M that has been verified to exist in the Serialize method.
Code:
void CMyWndDoc::Serialize(CArchive& ar) {
if (ar.IsStoring()) {
CString csFileName = ar.m_strFileName;
wstring ws = csFileName.GetBuffer(0);
string s(ws.begin(), ws.end());

I write a small application and using the following API to open the file:
hHandle = CreateFile(lpszFileName, GENERIC_READ, FILE_SHARE_READ | FILE_SHARE_WRITE,
NULL, OPEN_EXISTING, FILE_ATTRIBUTE_NORMAL, NULL);
Then I pass the hHandle to a DLL exported function, in that function, I will call
DWORD dwFlags = 0;
ASSERT(GetHandleInformation(hFile,&dwFlags) != 0)
to check if the handle is valid. However, the assert fails. And I use GetLastError to get the error code 6, which means invalid handle.
What is the problem with my codes?

The program then asks the user for a search string, which may contain white space. The program should search the file for every occurrence of the search string. When the string is found, the line that contains it should be displayed in the following format
nnnnn:Line Contents
That is the line number of the line, 5 columns wide, right justified, followed by a colon, followed by the contents of the line.
And this is what I've got so far:
Code:
#include<iostream>
#include<fstream>
#include<string>
#include<iomanip>
using namespace std;
int main(int argc, char *argv[]) {
ifstream inFile;
string fileName,
[code]....
But this doesn't work. It prints everything in the file, not just the lines where the string is found.

I have a project that has a few .asm files (assembly language code), I have the compiler/assembler set to create a list file for the assembly code and would like the debugger to use the .lst file for the source instead of the .asm files because in the .asm files the macros are not expanded like they are in the .lst files which makes debugging difficult sometimes.

If there are two projects A and B. A is created as .dll, while B is created as static library.
project A has a class "classA"
classA: public classB {
public:
testA();
};
project B has a class "classB"
classB {
public:
testB();
} ;
I want to make a symbol of classB::testB() in A.exp (like ?testB@classB@@QAEXXZ), can I do it by using __declspec(dllexport)?
Also if I make classB as a template class, can the symbol of classB::testB() be generated automatically in A.exp when building project A?

Here My requirement is replace the 4th line Mode: 2 instead of Mode: 1.
I was used seek method like below,
Code:
CStdioFile SaveFile;
CString strFilePath;
strFilePath = _T("C:Sara emp.txt");
if (SaveFile.Open(strFilePath, CFile::modeCreate | CFile::modeNoTruncate | CFile::modeReadWrite), &fileException) {

I 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.

I have this code, where I capture window and make copy to bitmap of it. I am working on rotation of bitmap. But my problem is that when I save the image to file the result is just a black screen. It looks like there could be some problem either in GdipCreateBitmapFromHBITMAP() or GdipGetImageGraphicsContext()
How to fix it and to get the rotated image?
Code:
// CODE 81 and 82 de facto no difference
#defineCODE85 // 81
#defineWINDOW_MIN_HEIGHT200
