QC82143

I've just submitted QC report 82143 about Controls.TWinControl.ControlAtPos not finding nested child controls.
I've found the bug (it seems) when trying to answer this question on Stack Overflow.
My suggested fix is included in the description of the report.

delphisvn updated to Subversion 1.5

I've updated delphisvn to use Subversion 1.5.
Good news that the official release now finally includes DLLs on Windows.
There's only source code for now, a downloadable release will follow.

Code signing large executables

I've been having some trouble signing some of my large (~1.8 GB!) executables. (In case you wonder, they contain a lot of multimedia content packed into a single file for downloading.)

The Microsoft Authenticode tools (signcode.exe, signtool.exe) failed with error messages like "Not enough storage is available to process this command". I've also tried signing them programmatically, using the CAPICOM API, but that also failed (the tools seem to use CAPICOM internally, too).

Looking around on the internet for a solution to this problem, I was very pleased to find out that Mono includes a code signing tool compatible with Authenticode. The tool failed as well... but there is source code! Here's the interesting part:

byte[] file;
using (FileStream fs = new FileStream (fileName, FileMode.Open, FileAccess.Read, FileShare.Read)) {
    file = new byte[fs.Length];
    fs.Read (file, 0, file.Length);
    fs.Close ();
}

;-) After a quick fix and a rebuild, I'm able to successfully sign all my executables so far. Big kudos to the Mono team!
