Call 64bit dll's function from 32 bit delphi code on 64 bit OS
Is there any way or trick to call a function in 64 bit DLL from Delphi code?
Any hardware manufacturer must compile their device drivers into 64bit code for 64 bit OS. So for example, graphic driver from NVidia is compiled to 64bit code for 64bit OS. Question is how to load 64 bit dll from 32 bit delphi code and call such function?
I hope somebody has already dealing with that.

Exactly the same as any other OS! I recommend installing to:
where C:\Tools\ has been created with a security setting of Everyone, Full
control. This assumes you are the only user of that PC. This works on my
Windows-7/64 system. Be aware that multiple Delphis should be installed
in increasing version number, so Delphi 5 after Delphi 4 and so on.
...Running 64 bit console application from a 32 bit Delphi GUI app?
I want to improve the usability of a 64 bit command line program so it
can be handled by fairly inexperienced users.
For this I need a normal Delphi program to have data specifiers etc,
which in the end results in a command file for the console
This is no big deal.
The problem is the following:
1) Can I start the 64 bit console app in Windows7X64 using the
CreateProcess API like I am used to for 32 bit applications?
Or are 64 bit programs different?
2) And if that is possible, can I somehow snatch what it sends to

I have a 32-bit Delphi 7 application which was deployed on some machines with Windows 7 64-bit. The application occasionally displays errors such as:
"Error reading ppDBText37.Border.Color: Invalid property value"
"Error reading Label24.Font.Ch: Property Ch does not exist" (here the name "Charset" was apparently truncated to "Ch")
I checked how those properties are declared on the form where the errors occurred, and all seems ok:
- First form (where "Error reading ppDBText37.Border.Color: Invalid property value" occurs):

I have a Delphi 2005 Win32 installation. When I originally installed it I had no need for the .NET Framework.
Now I would like to learn the .NET framework. Going back to the Delphi 2005 install disk and trying to install the . NET Framework has not been succesful.
Can I install the Turbo Delphi 2006 .NET Framework and have it co-exist nicely with my existing Delphi 2005 Win32 system?
...Createing 32 bit Delphi dll for Windows 64 OS
I develop a java application that uses a dll which is being written in delphi.
I use a 32-bit jvm on a 64-bit windows 7 OS.
When my java code calls the Delphi code, I get "unsetesfied link error".
I have checked the dll dependencies and saw that the dll depends on windows dlls, which are located in C:\Windows\System32.
The problem is (I think) that the dlls in that folder are 64-bit, and the jvm expects to recieve 32-bit dlls for the 32-bit application.
I know that the windows dlls for 32-bit are located in C:\Windows\SysWow64.

Any known issues with using Excel 2010 64-bit with a Delphi 32-bit app
My app uses the ExcelXP TExcelApplication object and nothing real
fancy. I basically opens Excel, gets a list of all the ranges, and
then updates the cells.
It works fine with Excel 2007 but I have one customer who is reporting
problems and he has Excel 2010 64-bit.
Also, is there a way for my app to determine if Excel is 32 or 64-bit
so that I can log an appropriate message.

What will happen when Delphi 64 bit arrives? Will further development on
Delphi 32 bit simply cease? I remember when Delphi 2 wa released, (way
back...) Delphi 1 and 16 bit development died down abruptly. That worries me
a wee bit. I am still very much involved in 32 bit development, and as much
as I would like to see Delphi 64 materialize, even now I would like Delphi
32 to evolve a bit beyond its current status.

I am responding to the various requests for 64 bit and the discussion
about the future direction of Delphi. I have a small company - we write
software for new and used auto dealerships - sales and finance - coming out
with accounting now and parts and service in the next few years.
Our customers don't care about 32 bit vs 64 bit, etc. They want me to
provide simple and convenient solutions to make their jobs easier.
We have stuck with Delphi 5 for many years - I should have upgraded 5
years ago but it did the job. We are now in the early stages of a

The usual guideline is to install in release order, Delphi 7 first, then
XE5. I would also advise installing in a dedicated, security open
directory such as:
