Hi!
I'm trying to restrict my exe to only one at any time. I've used the following code:
var
Mutex : THandle;
Mutex := CreateMutex(nil,False,'MyMutexName');
I got the following error in CreateMutex:
'Invalid Number of Parameters". How to create a Mutex in Delphi?
|
|
|
|
|
What version of Delphi are you using? It looks fine to me.
Try Mutex:= Windows.CreateMutex(Nil, False, 'MyMutexName');
And see what happens

If i have a .lnk file
that point to a link of http://.... type
HOW do i get the string http://.....
using IShellLink
GetPath or GetDescription or any thing else
do not give me a solution.
the GetWorkingDirectory give me system32 as path
but i want the string http://.....
any help???

well, .lnk is used to point to an object inside Shell namespace. I suppose you meant .url file.
.url file is actually an INI file, so you can try to use TIniFile class to parse your file, regardless of the extension it suggests.

You have not explained this 100 times. And despite repeated requests you still have not clarified what the content of the file looks like. The extension of the file (.lnk or .url) is irrelevant, it is the content that we have asked you to look at.

Hi Richard,
I view his file and it is not giving me any option of "Open with" as a normal shortcut files did. If i drag and drop that file in notepad than it give only garbage character not like you mentioned in your answer.
The problem is that
1) if problematically we create a shortcut using IShellLink and set the target name a URL than a shortcut of URL is created. Manually I don't think it is possible. But it is not correct shortcut. I did it by mistake in one of my project so I know this issue. This guy also create the link with installer and that's why he face this issue.
2) I will give him a suggestion that try to create a shortcut of URL using IUniformResourceLocator.
If he create a proper shortcut than only he will get the proper name of URL using GetURL.

That seems like the right way to go.

That is NOT the way to go. I want to read the file NOT MAKE IT.
Since if i get this problematic .lnk file
And Microsoft (trough the properties) can
read it as a link file so i can
as a programmer
But how?
|
|

1) Check what is the problem in installer to create the shortcut, there might be a solution to this problem... Which installer you are using ??
2) Worst case scenario is read the .lnk file as a text file and parse the http: string.

I took the link and read it trough hex editor
It is the same format as a "regular" lnk
sending you the link as text files
|
|
|

Yeah, I see what you mean.
I've tried using IUniformResourceLocator and IPropertyStorage, following the guide from MSDN on both Vista and XP (Internet Shortcut[^]), but none of them returns a bit. (Note they categorize this page as Legacy Shell Features, don't know if they've removed it or not)
The alternative way I could think of is to open this file through a hidden web browser control and then read the URL from it.
|
|

|

Obviously this is not the way to go.
because right mouse click on the file bring
the properties.
In the properties one sees the STRING http://....
So if Microsoft dose it we programmers can do it to
BUT HOW that is the BIG BIG qeuestion.
I have put this problem on 4 forumes
Delphi and c++ no one gave me an answer
Some went to URL file but the problem is the
.lnk file. And it is a .lnk file.
Well to sum it up good luck in the search for an answer.

Did you try asking Microsoft?
I downloaded your .lnk file and had a look at it via Properties. I noticed that although it displayed the URL text, it was not possible to edit it in any way, which suggests that even Microsoft did not accept it as a valid link. I guess there is some undocumented feature that allows access to it, possibly by having the details of the file structure.

P.S read the link into hex Editor and a "regular" link
and you will see the format is same

I tried to parse the file using IPropertyStorage with FMTID_Intshcut and FMTID_InternetSite, it turns out both of the property set is empty even though they can be opened successfully. Nevertheless, I can see the URL string from binary viewer.
I think they store data into both shortcut file and its property set. In stead of using documented methods to read data out using IPropertyStorage from property set, they might use some undocumented methods to read data directly from the file, as you said.

I agree with you. If they can, we can, as long as both of us are using the documented methods.
If the URL data is stored in Property Set of the internet shortcut file, File System will not keep this part of data when the file is moved by default.
Have you tried to parse the file using the original path where the link file was generated? If you can access the original shortcut file, can you check if the URL text in Properties is editable or not?
