如果用代码方式修改EXE文件中的资源文件解决方案

如果用代码方式修改EXE文件中的资源文件
现有一EXE文件,其文件中含有一TXT资源文件,如果利用代码修改其TXT资源文件的内容呢。

[解决办法]
这个需要相当的熟悉PE格式吧，买本看雪的软件加密内幕吧，里面有说这个的
[解决办法]
如果你知道TXT资源的ID，可以用LoadLibrary, AfxSetResourceHandle
[解决办法]
LoadLibrary
FindResource
LoadResource
LockResource
BeginUpdateResource
UpdateResource
EndUpdateResource

Using Resources

--------------------------------------------

This section contains code snippets for the following tasks:

Updating Resources
Creating a Resource List
Updating Resources
The following example copies a dialog box resource from one executable file, Hand.exe, to another, Foot.exe, by following these steps:

Use the LoadLibrary function to load the executable file Hand.exe.
Use the FindResource and LoadResource functions to locate and load the dialog box resource.
Use the LockResource function to retrieve a pointer to the dialog box resource data.
Use the BeginUpdateResource function to open an update handle to Foot.exe.
Use the UpdateResource function to copy the dialog box resource from Hand.exe to Foot.exe.
Use the EndUpdateResource function to complete the update.
The following code implements these steps.

Security Alert Using LoadLibrary incorrectly can compromise the security of your application by loading the wrong DLL. Refer to the LoadLibrary documentation for information on how to correctly load DLLs with different versions of Microsoft Windows.

HRSRC hResLoad; // handle to loaded resource
HANDLE hExe; // handle to existing .EXE file
HRSRC hRes; // handle/ptr. to res. info. in hExe
HANDLE hUpdateRes; // update resource handle
char *lpResLock; // pointer to resource data
BOOL result;
// Load the .EXE file that contains the dialog box you want to copy.
hExe = LoadLibrary( "hand.exe ");
if (hExe == NULL)
{
ErrorHandler( "Could not load exe. ");
}

// Locate the dialog box resource in the .EXE file.
hRes = FindResource(hExe, "AboutBox ", RT_DIALOG);
if (hRes == NULL)
{
ErrorHandler( "Could not locate dialog box. ");
}

// Load the dialog box into global memory.
hResLoad = LoadResource(hExe, hRes);
if (hResLoad == NULL)
{
ErrorHandler( "Could not load dialog box. ");
}

// Lock the dialog box into global memory.
lpResLock = LockResource(hResLoad);
if (lpResLock == NULL)
{
ErrorHandler( "Could not lock dialog box. ");
}

// Open the file to which you want to add the dialog box resource.
hUpdateRes = BeginUpdateResource( "foot.exe ", FALSE);
if (hUpdateRes == NULL)
{
ErrorHandler( "Could not open file for writing. ");
}

// Add the dialog box resource to the update list.
result = UpdateResource(hUpdateRes, // update resource handle
RT_DIALOG, // change dialog box resource
"AboutBox ", // dialog box name
MAKELANGID(LANG_NEUTRAL, SUBLANG_NEUTRAL), // neutral language
lpResLock, // ptr to resource info
SizeofResource(hExe, hRes)); // size of resource info.
if (result == FALSE)
{

ErrorHandler( "Could not add resource. ");
}

// Write changes to FOOT.EXE and then close it.
if (!EndUpdateResource(hUpdateRes, FALSE))
{
ErrorHandler( "Could not write changes to file. ");
}

// Clean up.
if (!FreeLibrary(hExe))
{
ErrorHandler( "Could not free executable. ");
}
