I answered your previous post: if it is C++ you need nothing special besides building the application in Release. Beware that .NET is not as easy.
For the C++ application to run on as many versions of Windows as possible (95, 98, Me, NT, 2000, XP) you should avoid using any "advanced features". The most simple applications (gialog based, or plain single-document like notepad) should then run on any of these OS versions if they are comiled in Release.
But you still don't provide much information about the executable. You already gave a hint that your program is not MFC. If it is not then Release builds will run on all sorts of machines with probably all OS versions. I have a VC2005 console release application compiled under Windows XP running on Windows 95 Intel 386@25MHz with 4 MB of RAM...

I'm using CMemFile class for saving the file in memory. But the serialization becomes very slow while using the CMemFile pointer for saving. I tried changing 'nGrowBytes' of CMemFile class to a high number. But it doesnt help. To put it in simple way, the code looks like this.
CMemFile* file;
CArchive ar(file, CArchive::store);
Serialize(ar);
I need to store a huge file in memory. But it takes very long time for serialization. If anybody knows the solution, plese help me.
Thanks.

From MSDN:
These memory files behave like disk files except that the file is stored in RAM rather than on disk. A memory file is useful for fast temporary storage or for transferring raw bytes or serialized objects between independent processes.
As far as I know, you are working correctly with the CMemFile (the work is the same as in CFile). nothing to do if it is slow, remember that the file needs to be dumped onto the RAM, and if it is a Huge file , then it should be slow....

Hi, Thanks for your reply. Is there a way I can store the serialized data in hard disk memory (not in RAM) so that serialization will be fast?
Thanks.

Hi,
I am working on a Windows application developed in VC++. The Windows application is required to capture the user inputs from Internet Explorer. For example, when user clicks on “Submit” button in the browser, the Windows application should be able to capture that event and also capture the text box values from the relevant web form. A similar situation is that the Windows application should also have a capability to populate the text boxes of a web form rendered by Internet Explorer.
To summarize, I need to implement an interface between my Windows application and the Internet Explorer so that the windows application is able to read from Internet Explorer and also populate the values in Internet Explorer. This involves the following:
1. Trapping the “Submit” (button click) event from Internet Explorer and Capturing text boxes in the Internet Explorer.
2. Trapping the page load event from Internet Explorer and populating the textbox in the Internet explorer.
I have searched for the related topics on web and also MSDN, I found that BHO (Browser Helper Object) is one of the option. I have tried to implement the BHO interface based on few samples that I found on some of the sites. However, it is not working yet.
Therefore I thought I would grab this opportunity to take help from the expertise involved with this Forum. Any inputs / ideas will be very helpful for me to progress in right direction.
I look forward to your response.
Thank you and regards,

Hi,
I need to copy a file of 24MB to a location on a network.
I use CopyFile method. But its extremely slow when the destination path is in a network.
If I copy a file on to the local drive its much more faster. Problem does not occur if the file size is less around 5kb.
Can anyone tell me the reason and an work around?
Thanks

As i recall CopyFile API is used by explorer applications such as windows explorer, total commander, explorerx2 etc....
try to copy the file manually, and see if it is slow...if it is, than nothing you can do , because the file transfer depends on the network connection.....

Thanks Yaron,
Indeed the network is slow and not CopyFile.
It took the same time to copy the file manually.
Cheers!

in the resource tab of VC 6, only adding BITMAP option is available. is it possible to add other image files as resource eg gif, tiff etc
|
|
|
|
|
Aparently you can add any type of file to the resources, but if you add not a basic file type (such as bitmap, icon etc.) it will appear as binary when you try to look at it...

Thats right, I want to avoid that, all i want is that other images can be added and displayed as bitmaps are added and displayed.

want to monitor the changes in the registry,By selecting on of the Root key then monitor the changes in that inlcude key,subkeys.....for name,value and status.
i Add the code in the thread function for monitoring as belowvoid MonitorThread(void* pParam)
{
//here am not understanding what event it returns
// RegNotifyChangeKeyValue(hKey1,TRUE,REG_NOTIFY_CHANGE_NAME|
// REG_NOTIFY_CHANGE_ATTRIBUTES|REG_NOTIFY_CHANGE_LAST_SET,hEvent1,TRUE);
DWORD dwFilter = REG_NOTIFY_CHANGE_LAST_SET, dwType, dwSize ;
char lpszUser[81];
HANDLE hEvent;
HKEY hKey;
LONG lErrorCode;
while(1) {
m_Sec.Lock();
//memset(lpszUser,0,81);
dwSize = 81;
dwType = REG_SZ;
// Open a key. Change second parameter to fit your needs.
lErrorCode = RegOpenKeyEx(hKey, NULL, 0,
KEY_NOTIFY | KEY_READ, &hKey);
// Create an event.
hEvent = CreateEvent(NULL, TRUE, FALSE, NULL);
// Watch the registry key for a change of value.
lErrorCode = RegNotifyChangeKeyValue(hKey, TRUE, dwFilter, hEvent,TRUE);
// Wait for an event to occur.
WaitForSingleObject(hEvent, INFINITE);
lErrorCode = RegQueryValueEx(hKey,NULL,0,&dwType,(unsigned char*)lpszUser,&dwSize);
//Add code for reading from the registry key
int item=pList->InsertItem(pList->GetItemCount(),lpszUser);
// Close the key.
lErrorCode = RegCloseKey(hKey);
m_Sec.Lock();
// Close the handle.
CloseHandle(hEvent);
// if(m_cStop1==TRUE)
// exit(0);
//Sleep(1);
}
}
For reading root key i put one combo box in the dialog and selecting one root key by pressing start button starts the monitoring ,if any changes occurs in the that rootkey registry display that key name,value ans status(create/modify/delete).
by pressing stop button stops the monitoring
Thanks,
Kiran.V

If this code is in a secondary thread, then the following statement is a recipe for failure:
int item=pList->InsertItem(pList->GetItemCount(),lpszUser); Instead you should be posting a message to the main thread (the one that owns the GUI). See here for why.

How to make the edit display the value by hex string?
such as
....
m_spin.SetBase(16);
m_spin.SetRange(0,0xFF);
m_spin.SetPos(0x2F);
...
the edit display "0x002F",what I want is just the string "2F" only.
ps:I tried to format m_edit in the function OnUpdateEdit(), but failed.
|
|
|
|
|
What is this m_spin ? A Progress bar ?
It has nothing to do with the edit control !
What you put in the edit control, it's up to you to format it correctly.
|
|
|
|
|
It may be an object of CSpinButtonCtrl..
nave
|
|
|
|
|
yes
CSpinButtonCtrl m_spin;
CEdit m_edit;
..
m_spin.SetBuddy(&m_edit)
...
