Visual C++ :: Windows 7 Explorer Doesn't Get Refreshed
Aug 4, 2013
I have created an application to burn my data files into DVD. The problem which I am facing is as follows:
Suppose I have a folder "Doc_Files" present inside "D:Data" location for burning into DVD. The correct behaviour of the application is, after writing the "Doc_Files" folder into disc, I have to immediately delete this "Doc_Files" folder from the "D:Data" location.
I am calling the DeleteFile() Win32 API for deleting those files which are present inside "Doc_Files" folder.
The files are getting deleted successfully but they are still shown in the same folder untill I do not terminate the application.
Till the application is up those files are still visible even after they are deleted. And as soon as I kill my application and refresh my data folder those files are gone, and the folder becomes empty.
I am making use of IMAPI interfaces and methods for burning process.
I have an application that Opens files with different extensions for viewing purposes only. I use MFC with Multi-Document template.
When I go to Windows Explorer in Windows 7 and right-click on Libraries - Documents, and scroll down to New, Explorer shows multiple links for creating new files with these different extensions.
My application does not create New documents. It just opens them for viewing purposes. In fact, I have disabled the New portion of the mainframe window.
My code includes: EnableShellOpen(); RegisterShellFileTypes(TRUE);
I am at a loss as to what portion of my code would have placed these links into Windows Explorer!
Is there any way to prevent them from being created in the first place?
I want to develop an application which can host multiple views of explorer (window), where as each window is totally separate from others. So that I can have multiple desktop views through my single explorer. Any built in feature in .NET ?
I'm making a small MFC module that should generate a report (formatted using HTML) and then display it for a user on schedule at 8:30 AM every day. Pretty straightforward stuff.
I compose my report and then save it as a local HTML file in the CSIDL_APPDATA folder. I then use the following calls to display it using the default web browser (Internet Explorer in this case):
Code: //Error checks are omitted for brevity CoInitializeEx(NULL, COINIT_APARTMENTTHREADED | COINIT_DISABLE_OLE1DDE); ShellExecute(NULL, NULL, strSaveFileTo, NULL, NULL, SW_SHOWNORMAL);
This module is run on schedule from the Task Scheduler. (The task is set up to run when a user is logged on, which is all the time for that PC. It is never turned off, put to sleep, etc. That computer has only one user that is never logged off either.)
This works perfectly fine when I test it by setting the task a minute or so in the future. But when the actual task is supposed to run at 8:30 AM, when the user wakes the screen all they see is a blank Internet Explorer page. (Note that if someone refreshes that page by hitting F5, only then my report is shown on the screen.)
So I started looking into it:
1) I checked that the file is properly saved (before calling ShellExecute) by reading it back and by comparing it with the original HTML markup that I saved earlier. It's all correct there.
2) I then checked the power saving options. That computer is set up to show screensaver after 5 minutes and to turn off screen after 25 minutes.
3) The web browser that causes this issue is IE version 11, with the latest updates installed. The operating system is Windows 7 Professional.
And why is IE showing a blank page only when computer is running unattended?
I am making a program which is going to print out a head image according to the input values entered by the user. Here is the code:
Code: #include <iostream> #include <string> using namespace std; void Sides() // draws the sides to take proportion
[Code] .....
At first i tried to work program like:
Code: cout << "plase enter which way you want to print out the head, with parted hair or bald." << endl; cin >> headstyle; if (headstyle != "bald" || headstyle != "parted hair" )
But it also had given the same mistake. The program compiles BUT; even if I put in the values bald or parted hair the program prints out "wrong input" then exits.
I installed FLTK 1.3.X from [URL] on my visual studio 2012 compiler and use PPP book for C++ programming [URL]. My problem is about filling a Shape in.
Code: #include <Simple_window.h> using namespace Graph_lib; int main() { Simple_window win(Point(100,100), 1000, 600, "Binary_tree"); Graph_lib::Circle c(Point(200,200),50); c.set_color(Color::red);
[code]....
When I run the program, All three Shapes are drawn on window but only the Rectangle is filled in! Why? set_color works for the three and apparently the set_fill_color is defined for all Shapes and it too should work but why it doesn't for Circle and Ellipse?
I wanted to stop the user from having access to USB flash drive while my program is reading data from it.I thought i could do so by closing the explorer at the start of my program and reopening it at the end of it.C Code to close and reopen the explorer?Or how to ban access to the USB flash drive?
I've just integrated the Windows SDK V7.0A into my VS2005 application, and I'm getting the dreaded "Application configuration error" when I try to run it on an XP machine.
It runs fine on the development machine, and some customer machines (Win7 and Win8), but will not run on XP due to missing/incorrect version dlls.
I've rebuilt all my libraries, but still no joy.
So, my first question is - If I upgrade the Windows SDK to V7.0A, do I also need to use MFC 10 and msvcrt10, or can I stick with MFC 8?
The next question is, how do I find out which dlls are missing, and which libraries or other dlls are requesting the missing versions?
In my application I have some type of windows showed in an instance of time, and an action shows a new one that i want have the focus all the time , in the way that i can't works with no one of the others. They all are windows, child windows an modeless dialogs, but i don't know how to do. I try use EnableWindow(FALSE) that all the others windows and dialogs, but not works.
I used to retrieve IP and NIC information by querying windows registry. Now I'm trying to use GetAdapterAddresses() API. Using GetAdapterAddresses() to get IP is not that easy, I need to dig a long deep as I check some examples so far, anyways my question is: Calling this API will return success on all versions of Windows ie: 32bits & 64bits ?
Though Microsoft has not opened any source, where this API is actually retrieving Windows IP information.?. Is it reading Registry or some windows file.
I am new in Visual C++ and I have to make an MFC application with "child" windows. Here is what i need to achieve - [URL] ..... As you can observe when you click on the cross of popup window or child window 2 both are closing.
I designed an app for work that lets you enter data in a much more efficient way, then it needs to paste this data into the very curmudgeonly interface we use for work. I designed this app a long time ago while at a different company, and I used VC++ 6. I'm still using VC++ 6, but in a vbox with windows XP.
The code is being called as part of a bigger function that determines what exactly needs to be pasted into the work app spreadsheet. I have to call each item separately because the work app does not take copied tabs the way Excel would or whatever, it just ignores them. And it also pops up boxes and such that need to be handled in other ways.
The result works just fine under Windows XP, but when I do it under my regular Win7 box or on the Win7 boxes at work, it does not work properly.
This sets the data up, Text being the data to be pasted:
Code: while (1) { if (OpenClipboard() == FALSE) { ::Sleep(1); continue; } HGLOBAL clipbuffer; char * buffer; EmptyClipboard();
[Code] ....
No infinite loops yet, again was just testing if it was OpenClipboard failing because it was being called again too quickly or something (and it did happen occasionally).
Then testing that the clipboard data is correct (this is always true), and pasting with keybd_event. SendInput is not available with VC++ 6.
If the ::Sleeps are commented out, it will paste the wrong data almost every time under win7. It seems like it pretty much uses the last thing to be copied in the function and pastes it over and over (but not *always*). If I uncomment them, it will work as expected, but it obviously takes longer. With ::Sleep(50), it works about 80-90% of the time. Obviously I can't have the wrong data being pasted, and I'd prefer not to have to wait like this--and perhaps on a slower system or a system that is doing other things it may take longer and paste the wrong thing. It works fine on XP even without the sleeps.
Did keybd_event become a separate thread or something? Am I doing something wrong with the buffers? (I've tried using CSharedFile too with GMEM_MOVEABLE | GMEM_SHARE | GMEM_ZEROINIT settings, exact same thing.) Why does it work fine under XP but not under 7?
The following code it taken from msdn library but it is failing to compile.
the following code has a header where all the variables used here are stored in header App.h.
The following lines are giving trouble:
Code: DialogBox(pApp->getInstance(), MAKEINTRESOURCE(IDD_ABOUTBOX), hWnd, pApp->About); error: 'App::About': function call missing argument list; use '&App::About' to create a pointer to member
Code: wcex.lpfnWndProc= &App::WndProc; error: '=' : cannot convert from 'LRESULT (__stdcall App::* )(HWND,UINT,WPARAM,LPARAM)' to 'WNDPROC'
There is no context in which this conversion is possible
I have struggled to send email from my MFC applications using severl methods:
1) http via my server - works but limited 2) M$ Outlook automation - works but not easily interchangeable between machines 3) Windows Sockets - available information simply too complicated 4) Purchase an ActiveX control - I hate black box solutions and am too cheap
I have looked at P. J. Naughter's class CPJNSMTPConnection v2.99 An MFC class to encapsulate the SMTP protocol [URL]
This approach requires the implementation of OpenSSL which turns out to be nothing short of a nightmare to install (so I never got it to run). I am looking for an example of an application that utilizes SMTP via Windows sockets api.
I have a 32-bit application that I've been maintaining for about 12 years and it runs on every Windows platform up to Windows 7. In all that time I've been using CWinApp::GetProfileXxxx() and CWinApp::WriteProfileXxxx() calls to read and write my program settings (about 70 settings) in the Registry. The settings are read from the Registry at start-up and written to the Registry when the program closes. There is also a method for the user to read and write the program settings to an INI file using the same code as the Registry access.
On my Windows 7 system the Registry read/write works just like it always has on all previous Windows versions. However, on some customer's Windows 7 machines there appears to be a problem with the Registry access. The program settings are either not being read from the Registry or are not being written to the Registry. I think the settings are not being written - but I don't know that. When the user uses the INI file the settings appear to be read and written.
The customer has complained a bit (I'd complain too) but doesn't have the time or doesn't want to take the time to run some simple tests for me to find out what's going on with his Windows 7 system.
So here is my question: Are there any user account settings or permissions that can block the program's access to the Registry? He claims he is an Administrator but I can't even get him to verify that.
I want to do conditional compilation based on whether it is windows 7 or windows 8. Here is the code below.
#if (_WIN32_WINNT >= 0x0602) //Condition to check whether it windows 7 or 8 .Based on this we can load msxml 3 or 6. #import <msxml6.dll> #else #import <msxml3.dll> #endif
Im building the above code in windows 8 machine.
Issue here is _WIN32_WINNT should have a value 0x0602, it means it is running in windows 8 machine.Instead it has a value 0x0601 (Means it is taking windows version as windows 7 defined in sdkddkver.h).Im not sure after installing windows 8 sdk im not able to see any include or lib files in the path below C:Program Files (x86)Microsoft SDKsWindowsv8.0A . but i can see all include and lib files of sdk version v7.0A available although i did not installed it.
When I write to the Windows 7 Registry at HKEY_LOCAL_MACHINE, I get a return code of 5 which is the "access denied" message when I execute RegCreateKeyEx.
This happens even if the User has administrator rights.
How can I tell Windows 7 to allow the program to write to the registry?
The application is a 32-bit application and it should be allowed to run in either a Windows 7 32-bit or 64-bit machine.
I noticed that when I run certain popular programs, a User Account Control dialog box comes asking:
"Do if you want to allow the following program from an unknown publisher to make changes to this computer".
Should my application call User Account Control and if so, how do I do it in C++ Visual Studio 2008?
I also found out that 64-bit Windows machines have two registry hives. Is there a different code to handle the same task?
By using visual studio 2010, I have problem calling up on screen keyboard using line below for Windows 7 64 bit.
WinExec("OSK.EXE", SW_SHOW);
However, it is working fine on windows XP 32 bit. How to call up on screen keyboard for 64 bit windows?
Code:
int _tmain(int argc, TCHAR* argv[], TCHAR* envp[]) { int nRetCode = 0; HMODULE hModule = ::GetModuleHandle(NULL); if (hModule != NULL) { // initialize MFC and print and error on failure
