My application uses Firebird 2.5 and the installer needs to check whether any previous version of Firebird is installed on the system.
Earlier I was checking particularly version 2.0.1 by registry methods, but now I need to check for any version.
I have found some service API to retrieve version no, but that requires writing a small c/c++ program. I'm looking for some registry / other methods. Any clues ?
Go to:
Control Panel -> Programs
You will see Firebird with version number installed

I want to support older Windows versions, but non updated 7 and pre 7 operating systems do not support sha256 code signing, so they cannot detect that the executable/file is properly digitally signed.
My questions are:
How can i check if a system has this update (KB4474419) installed, or basically check if it supports sha256, without causing false positives (for example detecting new windows 10 machines as not having the update by mistake)
How to install this update in the background, without user knowing, and check if installation was successful (in order to see if we should restart the machine or not, in case it was successful) ?
(I want to implement it using c/c++, so native windows APIs are available to solve this)
WUA defines interfaces and objects that are accessible from Visual Basic, Visual Basic Scripting Edition (VBScript), JScript, and from C and C++.
I suggest you could try to use wuapi.h header. This header is used by Windows Update Agent API. And there are some COM interfaces that can be used from C++.
My application needs to determine whether it is running on Windows PE.
Neither the deprecated GetVersionEx function nor the preferred alternative Version Helper APIs offer any indication whether I am operating on WinPE, only indicating the version of the OS.
This reference lists the compatible APIs for WinPE, so I need to be able limit my app to those APIs.
How can I programmatically determine from my App whether I am on WinPE, and which PE version is running?
If you simply need to determine whether you are running WinPE or not, you can check for the presence of the key MiniNT in HKLM\System\CurrentControlSet\Control or HKLM\System\ControlSet001\Control. If it is present, you are on WinPE 2.x or higher.
Cited in MSDN docs here, you can see which version of Windows PE youare running at the registry key HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\WinPE. That reference also gives a table of features and functionality each version will provide you.
For very old versions of Windows/WinPE before 2.0, check the version of %SYSTEMROOT%\SYSTEM32\FACTORY.EXE.
I've been working for a couple of days with GTK3+ under Linux in C++ and I've used Glade to design my GUI. In my C++ code, I call gtk_builder_new_from_file instantiate the GUI.
Now I was trying to do the same under Windows. So, I downloaded the latest version of GTK+ (3.6.4, all-in-one 64-bit bundle). The problem is: I can't find the function gtk_builder_new_from_file. I've searched for it in all files too, but it seems not to be there. I've checked the documentation, and this function should be present since version 3.10.
So, why can't I find it? Is a Windows compatibility issue?
3.6.4 is a smaller version number than 3.10 so there does not seem to be any mystery here.
You should use gtk_builder_add_from_file () instead if you can't find a newer Windows bundle.
I would like to install ColdFusion Builder 2 Update 1 as a Plug-in for Eclipse 4.3.
The install seems to work without errors but when I attempt to register my license code, I get an error dialog box that says:
"The chosen operation is not enabled."
None of the CFB features appear in Eclipse.
In some of the documentation that I've found it references installing to Eclipse 3.6.
Can CFB 2u1 get installed on Eclipse 4.3? If not, does someone know which version of Eclipse to use for CFB? Hopefully it is something recent or I'm doing something wrong for the install.
I don't know if it matters, but I'm running:
Windows 7 Pro 64-bit
16GB RAM
According to the ColdFusion Builder System Requirements page one needs Eclipse 3.7.1. Having tried to install it on versions later than that, failing, and talking to Adobe about it, they confirmed that one needs that precise version. More recent ones won't do. This is a bit subpar on the part of Adobe, but so be it.
is WinHttp.dll a standard Windows file? My application depends on it, but i'd rather not deploy it in my application setup, unless it is neccessary.
As per: http://msdn.microsoft.com/en-us/library/aa384273(v=vs.85).aspx
WinHTTP 5.1 offers improvements over version 5.0. It is included in the operating system
