"Cord"? Did you mean "code"?

Hello,
I'm hoping someone here can help me. I have been asked by a business unit in my company to find the cause of why a dotNet program cannot run on a certain Dell model laptop. It runs fine on a newly image laptop of all different Dell model of laptops and desktop, but for some reason on a Dell M8600 it fails to open. The M8600 has the same .Net 4.5.2 install. Could there be a missing driver that is needed to load a dotNet executable?
I'm sorry if any of my statements don't make sense. I'm not a programmer or scripter. So I am way out of my comfort zone here. I am completely loss as what could be the reason why the program is failing on a particular model of laptop.
I was told that the program was written in dotNet 4.0. I'll get the error message and application event logs tomorrow when I go back into the office.
Any assistance would be greatly appreciated.

The are no drivers for a .NET application.
The only things you need installed is the version of the .NET Framework the app was written against.
Now, if your app uses any database such as Oracle, SQL Server, Access, MySQL, SQLite, ..., then you'll need a client installed for the database engine you're using and any drivers that it needs.
But, without the error messages any event log messages, it's pretty much impossible to tell you anything useful.

OK, this is definitely a "your code" problem.
The exception, "System.NullReferenceException", says that you're trying to get/set a property of call a method on an object that your code is ASSUMING exists, but doesn't. You're not checking for the existence of the object you're trying to do something with before you try and use it.
Somewhere in the method "Form1_SizeChanged", you goofed.

Thanks you Dave for the suggestion. I passed this on to the author of the program and he fix his program to account for the window size. You have been a great help!

Just wanted to let you know that the issue was definitely the method you had mention. I passed your information onto the author of the program and he fixed the issue. So Thanks again.

The "CLR20r3" in the log looks suspicious.
This frequently pops up when the EXE targets a .NET framework that is not installed.
For example, an app targeting the "full" .NET 4.0 Framework will fail if only the "Client Profile" 4.0 Framework is installed.
Insure that the EXE is actually targeting 4.5 and that the 4.5 framework is installed.
(4.5 did away with client vs. full frameworks; the log makes reference to 4.0).

Thank you. The client in question has 4.5 installed. Would it fix the issue if I uninstall 4.5.2 and installed 4.0? I tried that and it didn't work so don't know if I correctly uninstall 4.5.2 completely.

It should never be necessary to "uninstall" a particular version because they can all co-exist.
You just need to insure that the app you are trying to run has a compatible framework installed.
Leave 4.5 alone and install the 4.0 frameworks from the Microsoft sites. Try the "full" 4.0 framework; if that doesn't work, try the "client profile" (though that probably won't make a difference if the "full" 4.0 doesn't work).
Though the log doesn't seem to reflect it, the app could be trying to use something else that is missing if the app install you were given was incomplete; e.g. SQL Server CE dll's; 3rd party libraries).
The person who created the app should really be involved.

That's not going to work - 4.5 is an "in-place upgrade" to 4.0, so you can't have both on the same machine.
Everything that works in 4.0 is supposed to work in 4.5, so there's no need to try to install 4.0 as well.

Fair enough. Thanks.
I suppose then he should try re-installing 4.5 in case the installation is corrupted.
Better yet, get the app source code and debug it.

there is a method to compute bell curves in vb.net how to excel
Thanks in advance
|
|
|
|
|
Uhhh....what?
If you're looking for a method in the .NET Framework to calculate a Bell curve, there isn't one.
You can try and write your own, the description of which can be found here[^].

Hi,
I have a VB.NET winforms application which I distribute from my website and recently I am getting some issues reported which may be a build problem. The computer I use to create the application and installer (I use Inno Setup) is windows 7 with a .NET 4.5 framework and built with VS 2013. My application only targets the .NET 3.5 framework. The computer I used to build the application with used VS2008 but since I migrated to vs2013 there are some weird graphical problems, such as GDI not working properly (some lines are not being drawn properly), some file location issues and problems with My.Settings.
Incidentally, I have vs2010 installed where I work and that doesn't have any problems.
Any help would be greatly appreciated. I don't really want to go back to vs2008 but I will if it's the only option.

Since we know nothing at all about your code it's impossible to tell you what's happening.
What I can tell you is that it has nothing to do with the version of Visual Studio you're using.

Yes I appreciate that, but it was more of a framework question rather than specific code.
I'm relieved that Visual Studio isn't to blame (in this instance!).

Without specific details it is anyone's guess what might be happening. You need to collect much more detailed information from your users as to exactly what happens, and under what circumstances.
