Question

我有一个使用ShellExecute打开用户传入的文件的方法。编写它是为了接受带有unicode字符的文件名。它适用于txt和pdf文档，但是当我使用包含unicode字符的图像文件进行测试时，我得到了FILE NOT FOUND错误。我正在使用以下文件名测试图片：ams’.jpg和ams’.png（’ ALT + 0146 ）。

void sys_ShellExecute( PA_PluginParameters params )
{
LONG_PTR returnValue = 0;
LONG_PTR len = 0;
char returnText[255]; // MWD & Mark De Wever #12225
INT_PTR  howToShow;
//char *pChar;

//char *operation = NULL;
//char *file = NULL;
//char *parameters = NULL;
//char *directory = NULL;

PA_Unistring *UnistringFile; 
PA_Unistring *UnistringOperation; 
PA_Unistring *UnistringParameters; 
PA_Unistring *UnistringDirectory; 

PA_Unichar *file; 
PA_Unichar *operation; 
PA_Unichar *parameters; 
PA_Unichar *directory; 
PA_Unichar *pChar; 

// Get the function parameters.
//operation = getTextParameter(params, 1);
//file = getTextParameter(params, 2);
//parameters = getTextParameter(params, 3);
//directory = getTextParameter(params, 4);

UnistringOperation = PA_GetStringParameter( params, 1); 
UnistringFile = PA_GetStringParameter( params, 2); 
UnistringParameters = PA_GetStringParameter( params, 3); 
UnistringDirectory = PA_GetStringParameter( params, 4); 
howToShow = PA_GetLongParameter( params, 5 ); 

operation = PA_GetUnistring(UnistringOperation); // AMS /28/14
file = PA_GetUnistring(UnistringFile); // AMS 2/28/14
len = (PA_GetUnistringLength(UnistringFile) + 1); // AMS 2/28/14
parameters = PA_GetUnistring(UnistringParameters); // AMS 2/28/14
directory = PA_GetUnistring(UnistringDirectory); // AMS 2/28/14

//if ((strcmp(_strlwr(operation), "open")           != 0) &&

    strncpy(returnText, message->InvalidShowConstant, 255); // Mark De Wever #12225 replaced the line above
}
else
{
    pChar = file; // added 10/28/02 shellExecute wants backslashes
    do {
        if (*pChar == '/') {
            *pChar = '\\';
        }
    } while (*pChar++ != '\0') ;

    if (directory != NULL) {

我做了一个快速测试，以下对我来说非常好：

LONG_PTR returnValue = (LONG_PTR) ShellExecuteW(NULL, L"open", L"C:\\ams’.jpg", NULL, NULL, SW_SHOW);

因此，问题必须与传递给ShellExecute()的参数值有关，而不是与包含Unicode字符的文件名相关。

shellExecute＆＃34;找不到文件错误＆＃34;包含包含unicode字符的图像文件
