The problem is bitness.
Either the target machine doesn't have 64-bit ACE (Access) installed, or your code is running as 32-bit, not 64. You cannot mix 32- and 64-bit code in the same process.
You have to match the ACE bitness to your application, or the other way around. If the target machine has 32-bit Office (Access) installed and your app is compiled as x64 or AnyCPU running on a 64-bit machine, you'll get this message.
If your code is compiled x86 only and there is only 64-bit Office (Access) installed, you'll still get this error.

Huh?? There is no 64-bit version of JET. It's 32-bit only and was replaced by ACE. ACE comes in both 32- and 64-bit flavors.

If you are using Visual Studio 2010, then the issue should not arise. Maybe some of the files are corrupt and that is causing the problem.

Hi
Thanks all for your help.
I found the problem rely on your advice.
I changed the target platform from configuration manager to x64 bit and the problem solved.
thank you again!!

Hi
It was printed with a barcode font, but
Scanner can not read it
There are special rules for barcode printing
Please advice please
Chab should the photos or conventional
Thank
|

First of all, you should learn that there are many barcode formats. And barcode readers may need to be configured to read your format - it is not advisable for a barcode reader to beconfigured to read any format any time, as the error rate is likely to increase. Configure the really required format only.
|
|
|
|
|
I have to deal with barcodes a lot, just not from a programming stand point. We exclusively use 3of9 as the format. With 3of9 you must have a leading * and a trailing *. Those are the starting and ending points for the software to read the barcode.
I am sure other formats are different, just research your format.

Depending on the ink, paper, and barcode size, the ink can spread after printing, making the barcode unreadable. This phenomenon is called "dot gain".
The way to correct for it is "bar shaving"; you remove column(s) of pixels at one or both edges of the bars to make them narrower. For 2D and GS1 barcodes, which have both vertical and horizontal dot gain, you can do bar shaving in two dimensions. (This is also called "erosion"; an operator from mathematical morphology). This is the mathematical inverse of dot gain.

hi
i want to make a setup of my c# project that i create on visual studio 2010 and use access database (for some reasons), but i don't know how i create to run on a server.
thnx

There is no difference between creating a setup that runs on a workstation or on server. It's Windows in either case and everything still works the same way between the two editions as far as a Setup is concerned.
|
|
|
|
|
I do not think that that's a problem of the setup: You'll need a Windows Service instead of a Windows (GUI) / or Console application. That means some bigger changes to your project.
|

what can i do for this problem so that i manage to run my program
through the server ??
|
|
|
|
|
You're going to have to define exactly what you mean by "run the program through the server".
Are you placing the executable and all related code in a share on the server and client machines will launch it from there? Are you saying that you want the client machines to remote desktop into the server and run your app on the server? ...??
|
|
|
|
|
i want to have my database in a server and my program in clients so the clients can get correct information from the database any time they want.
Also i want users have the ability every time they make changes in some records these records have to be
locked for others users until this user have finished...
|
|
|
|
|
OK, so you can either create two seperate installers, one for the database and one for the clients, or you can combine the two and the first client to install would go through the process to install the database on whatever SQL server the user specifies.
You REALLY have to be careful with record locking. It's just about never a good idea. The primary question is what happens if a client locks a record and then the client machine hangs?? How do you recover from a locked record that shouldn't be locked any more??
Concurrency issues are not easy to solve and you have to do research into what you're options are and how they affect your business process code.

the setup process for the server it is the same with the setup process on laptop ?
or i have to follow different way to make the setup process for server?
|
|
|
|
|
What did i say? IT'S NO DIFFERENT. Windows Server is still frickin' Windiws! Everything works the scant same way.

I have a C# 2008/2010 application that is currently accessed as a dll file and I would like to change the application so that the dll is accessed though as a reference. The code that calls the dll is a process and the code looks like the following:
Process theProcess = new Process();
theProcess.StartInfo = new ProcessStartInfo("filename.ext");
theProcess.StartInfo.Arguments = "args here"
theProcess.WaitForExit();
theProcess.Start();
The problem is the dll is currently placed in various locations like unit test area, client acceptance testing, system testing, and then into production by the 5 applications that call it. The application currently obtains the various locations based upon values in the app.config file. If I add this dll has a reference to the programs that call it, how will I tell those calling programs where to obtain the 'correct' directory location? Would I use the app.config file?
Can you show me code and/or explain to me how to solve this issue?
|

Usually, the .DLL referenced will be in the same folder as the .EXE calling it.
But, if that's not possible because of multiple applications refering to the same .DLL, you can put it in another location suiteable for the task, such as a folder under C:\Program Files\Common Files\companyName.
Read this[^] for more information on your options.
You could use a probing path in the app.config for all the applications, but all applications would have to be under the same folder under program files and the .DLL path would have to be under the base application path.
|
|
|
|
|
If I place the dll in the same directory path for all 5 programs to access, that would be a good idea!
Currently each program executes the dll by the value placed in the app.config file for each of the 5 applications. Would I be able to continue to use the same logic? If not,what would need to change?
