Yes, because start uses ShellExecute or ShellExecuteEx.
However, if you use FindExecutable with the filename of your HTML file, you get back the executable that is registered to handle the open verb. You can then use that with ShellExecute.
For example, FindExecutable (when called on an HTML file) gives this for me (it's Google Chrome):
C:\Documents and Settings\my-user-id\Local Settings\Application Data\Google\Chrome\Application\chrome.exe
So, you can do something like this:
LPCTSTR url = "file:///C:/Documents%20and%20Settings/u404261/Desktop/a.html#plop";
TCHAR path[32768] = {0};
DWORD nChars;
if (SUCCEEDED(PathCreateFromUrl(url, path, &nChars, 0)))
{
TCHAR execName[32768] = {0};
if ((int)FindExecutable(path, "c:\\", execName) > 32)
ShellExecute(0, "open", execName, url, "c:\\", SW_SHOWNORMAL);
}
We use PathCreateFromUrl to get a Windows path from the URL, as that's what FindExecutable acts on.

Hi any one plese help me
i am using GetVolumeInformation in my code for comressing some files and folder.
the used code is below
CString strDir = _T("D:\\CompressionTest");
TCHAR volBuff[256];
LPTSTR lpVolumeNameBuffer = volBuff;
DWORD nVolumeNameSize = 256;
LPDWORD lpVolumeSerialNumber;
LPDWORD lpMaximumComponentLength;
LPDWORD lpFileSystemFlags = 0;
TCHAR sysFileBuff[256];
LPTSTR lpFileSystemNameBuffer = sysFileBuff;
DWORD nFileSystemNameSize = 256;
if(!GetVolumeInformation(strDir,lpVolumeNameBuffer,nVolumeNameSize,lpVolumeSerialNumber,
lpMaximumComponentLength,lpFileSystemFlags,lpFileSystemNameBuffer,nFileSystemNameSize))
{
CHAR szBuf[80];
DWORD dw = GetLastError();
sprintf(szBuf, "failed: GetLastError returned %u\n",dw);
MessageBox(NULL, szBuf, "Error", MB_OK);
ExitProcess(dw);
}
plese inform me if i am doing any mistakes

you are missing a trailing "\"
For eg:
CString strDir = _T("D:\\CompressionTest\\");
Error code 123 indicates:
From MSDN:
ERROR_INVALID_NAME
123 (0x7B)
The filename, directory name, or volume label syntax is incorrect.
You need to google first, if you have "It's urgent please" mentioned in your question.

i tried trailing "\" like below
CString strDir = _T("D:\\CompressionTest\");
then its giving compilation error
D:\AcqUT\TestZip\TestZip.cpp(27) : error C2001: newline in constant
D:\AcqUT\TestZip\TestZip.cpp(27) : fatal error C1057: unexpected end of file in macro expansion
while using trailing '\'
CString strDir = _T("D:\\CompressionTest'\'");
no compilation error but mentioned problem was not resolved

|
|

you need to use a "\\" in the end _T("D:\\CompressionTest\\"); otherwise you are putting a escape sequence
You need to google first, if you have "It's urgent please" mentioned in your question.

It's not a mistake per se, but since you are using MFC, why not have:
CString szBuf; <br />
DWORD dw = GetLastError(); <br />
<br />
szBuf.Format("failed: GetLastError returned %u\n",dw); <br />
<br />
AfxMessageBox(szBuf);

I have the same problem, and I am not using MFC.
From several partiotins that I have, the GetVolumeInformation failed 2x.
Using the FormatMessage
char *errorBuf = 0;
if (
FormatMessage(
FORMAT_MESSAGE_ALLOCATE_BUFFER |
FORMAT_MESSAGE_FROM_SYSTEM |
FORMAT_MESSAGE_IGNORE_INSERTS,
NULL,
GetLastError(), //the error message
MAKELANGID(LANG_NEUTRAL, SUBLANG_DEFAULT), // Default language
(LPTSTR) &errorBuf,
0,
NULL)
)
{
MessageBox (NULL, errorBuf, "BuildIndex - Error",MB_OK);
LocalFree (errorBuf);
}
The message box says "The filename, directory name, or volume label syntax is incorrect"
But explorer shows the right label for those partitions.
So It must be another way to collect information and getting the right label.
==== EDIT ====
Never mind, I got the answer. I added '\\' to the drive name. The funny thing was, It was successfully without adding the '\\' on some partitions

Hello,
I am having troubles with applying themes to my application. I have a MFC project developed under VS2008 which can by default settings change the appearance (theme) of the mainframe. It is the SDI application with splitters where I use many CformViews. The problem is that the views are not themed at all. I searched many site for solving that problem but found no answer.
- My application automaticly generate the manifest, so I don't think the problem is in that. The mainframe changes the theme.
- in my app class in InitInstance() I call
INITCOMMONCONTROLSEX InitCtrls;
InitCtrls.dwSize = sizeof(InitCtrls);
InitCtrls.dwICC = ICC_WIN95_CLASSES;
InitCommonControlsEx(&InitCtrls);
what I found is important for initializing the themes. It was automatically done by VS in my app.
Can you please help me to solve my problem. Do I need to change something in my views?
Thank you very much, Tomas

Hi,
I am working in development of Active X control in VC++ .I need to create a property for FONT to have GetFont & SetFont. I have developed with default setting when I debug the code using Activex control test container I can go GetFont function in the code when I invoke GetFont but I try for SetFont it doesn’t moves to SetFont instead it goes to GetFont.
When I check with MSDN I came to know that IFontDisp is used which is inturn inherited to IDispatch which provides write access to set function only when we set the flag DISPATCH_PROPERTYPUT.
Could any one suggest me what are the steps to be taken to move the into Setfont function.
Thanks in Advance,
G.Girish

What is the problem of integrating the DISPATCH_PROPERTYPUT? It is the key (but I have no clue)

Hello,
I am doing socket programming in VC++. I have two applications for Server and Client(in VC++). Message can be send/receive with these two applications from server to client or vice-versa.
I download one HL7 Toolkit. I want to communicate this Toolkit with my applications. They did socket programming, but in Java.
I want to know, can we send data if sender side socket is created in VC++ and on receiver side socket created in Java. Is socket programming is platform independent?
Thanks in advance

Socket programming is really platform independent, but watch out for bit order. (LSB and MSB)
Consider it as posting bits through the cable.

Yes, it is platform independent, but you need to take care below points when going across different platform (in terms of processer)
1) Before send data, convert your data in to network type. (ex. using "htonl" function.)
2) if you passing whole structure as a binary data then need to take care about padding. (use __attribute__((__packed__)))

thanks.
But now i can't send or receive the data from Toolkit which i download. My application is in VC++ and Toolkit is in Java. Is there any function i have to add in my application.

is your toolkit is Socket server or socketclient. Are you connecting on right socket port?

After running your application at both side (server/client) check that your application able to bind on that port or not? You can use "netstat" command in window.

Hey man, code is working, i have tested it.
I think something else in your application which is causing issue.
Just cross check below basic things
1. Message box not going background, and thats why you are feeling that program is stuck.
2. You have given right IP at client side.

Hi,
May i know whther is it possible to use UrldownloadToFile in batch file...if yes pls let me know...
|
|
|
|

I don't think so. However, you can use the API in an executable and run the executable from a batch file (command line parameters to control it, may be).
It is a crappy thing, but it's life -^ Carlo Pallini

yes you can, if you know how to load the dll and invote the api from it in bacth file.
