装入资源

[飘雪831101]

如何把图标等通过BeginUpdateResource,UpdateResource等加入啊.

[飘雪831101]

我用BeginUpdateResource("Comm.exe",FALSE)时,返回值总是为NULL,为什么啊?
它的第一个参数是什么的可执行文件啊?我一直不明白.

帮你查了下MSDN,不敢确认自己说的对不对:)

BeginUpdateResource
The BeginUpdateResource function returns a handle that can be used by the UpdateResource function to add, delete, or replace resources in an executable file.

大概的意思是:BeginUpdateResource返回一个能被UpdateResource函数添加,删除,或者替代资源的句柄..

而
BOOL UpdateResource(
HANDLE hUpdate, // update-file handle
LPCTSTR lpType, // resource type
.....)
第二个参数,资源类型中没有.exe,所以就返回NULL..

GetLastError

函数调用出错就用GetLastError取错误码，判断出错原因~

有用过BeginUpdateResource,这些的吗?请大家帮帮忙啊.

给你一个实例:

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."); 
}

如果还有疑问,可查msdn,其中有比较详细的操作过程介绍.

选择一个.ico图标,然后updateresource,放入可执行文件中.
怎么实现啊?
