.NET Application Hangs When Calling DLL

Dec 28, 2010

Its been running in production for over a year and this is the first time I saw this behaviour. The application is a VB.NET Console Application which is triggered by MQ server. This application uses a class library which is part of the same project(Say 'abc.dll'). In production around 40+ instances of this exe are running and all of them use the some of the functions from 'abc.dll'.

Last week, we noticed that all the 40 instances were shown to be running in the task manager but they were not doing any activity. There was no exception thrown or error logged in Application logs or System logs. To frantically debug the problem, I tried isolating the problem.

With all these 40+ exes hung up, I wrote a small aplication which would use a reference to this 'a.dll', create an object of one of the classes in that dll and execute a method in there. I was printing console.writelines in between to see to which point it gets to before erroring out.

To my surprise, I found that at the point where I was creating an object of a class in 'a.dll' this sample test application would also hang just like the others. No exceptions thrown. So I killed all those applications as a last resort and then when I restarted all of them, everything worked fine.

I couldn't find any explanation for this behaviour. Since it was a critical error affecting a production system(blanking out the application for 3+ hours), I have to give a very good explanation as to why this would occur. how it can be prevented in future.

(Side note: the servers running these appilcation do not have a maintenance schedule and are supposed to be up for couple of months together.

Application Calling Fortran Exe

Nov 18, 2010

I am running one fortran exe in .net application(calling from command line with the help of system diagnostic process). If we directly click on fortran exe, it shows inputs to enter for fortran in command window, after input entered it gets executed.

How to achieve this with .net application? Right now, after clicking on button in vb.net form, exe get's opened in command window, but it is blank, and gets hanged. [code]

Calling Another Application From Within A VB Program?

Feb 9, 2011

I have written a VB Program for calculating Power requirements for Heating Water, Air etc. There are some standard formulae, which require inputs in fixed units. The user may have data in other units, which will then need conversion.Example: Formula needs Airflow in Cubic Meters/ Minute, where as user has data in Liters/Second.I do not want to write code to do Unit Conversions from within my Program. There are readily available FREE Applications for doing the conversions. I have one such Application, which I want to bundle with my VB program.How can I Code in my program, so that when the user clicks a Button " Unit Conversion ", the bundled program will open.This is like clicking on a Hyperlink in a Program or Document and a Web Browser opens.

Calling Asp.net Function Within Web Application?

Oct 26, 2011

Is it possible to call a function within an asp.net web application from outside that application e.g. with VB.net? If so it would be great to see a hello world type example.

For arguments sake lets say I have my function "helloworld" in a class file within web application: [URL]

My ultimate goal is to enable some reliable / robust scheduling of functions within asp.net. I have read multiple examples about using web services / custom services running on the server etc but I don't really get the implementation.

.net - Calling New StackTrace Blocks When Closing Application

Sep 12, 2011

I just did some analysis by using a global function which is called GetCallingMethod in my case.

Mostly it works great. But some cases the application is blocked. It is blocked when closing the application. When going to "pause" in Visual Studio, it stays on the new StackTrace line forever.

In my application I am using third party references, multithreading and several classes. But all that should not be a problem and should not lock the tracer class as far as I imagine. I am using Visual Studio 2010 Ultimate in this case.

This line will never be left in development area. Application will is frozen. Try/Catch will not force the procedure.

Calling A Function That's In A Module In External Application

May 25, 2012

I have an application (app.exe) that has a VB Module in its source code (Module1). The module has a function called Function1. I need to call this function from another application. The module is not marked as public, so adding a reference to app.exe won't work. I'm trying to use reflection (Assembly.LoadFrom()) but unless I'm way off base, the module would have to be a class in order for me to get an instance of it.

Please nobody ask me "what have you tried?" I tried a million different things and let's just say "none of them work." So I'm looking for someone that has specific experience with doing exactly what I'm trying to do. If you don't have that experience, please move on to the next question and ignore mine.

Calling Javascript Function From Within Desktop Application?

Jun 24, 2009

I'm trying to do something which i am not sure is possible, im hoping someone will be able to prove me wrong.I have a desktop application written in VB .net which needs to post to google analytics, the interface they provide is javascript based. At the moment my application opens an internet browser, goes to a specified URL which in turn executes the javascript contained within, this is cludgey and memory gobling!

Is there any way of importing a javascript file and calling a javascript function without opening a third party browser? would preferably not want to use the browser control either.Is there a way of instantiating for instance a javascript engine and passing it the commands?

VB: Get Compiled DLL's Calling Application Info; COM Security?

Oct 15, 2010

Through COM, one can potentially gain absolute control over a target system. For example: using javascript's ActiveXObject object in IE, one can create certain objects which were designed to have direct access or interaction with system properties and files.One would think common sense dictates users disable ActiveX features in IE immediately after installing the browser to ensure their system is protected while surfing the net, or at least paying close attention to which websites they permit. But, I doubt many average PC users know how or why to do this, or just get tired of mirco-managing it over time. I think any PC user or admin my COM class caters to would greatly appreciate not having to deal with that. Thankfully it looks like IE versions come packaged with ActiveX disabled by default nowadays.

I've built a very versatile COM class library in VB. I didn't intend for it to be callable from any website, but that feature is just part of the COM platform. I'd like to prevent the library from being called from IE unless the website is on a white-listed domain to proactively protect the user (and ultimately their entire intranet) from harm from malicious websites. What would be the best method in VB.Net to tell which application called my DLL, to be able to tell if it was called from any command or process originating from IE? And, what domain called my dll? System.Environment.GetCommandLineArgs()(0) gets me the calling application path. With this info, I can compare it to a black/white-list of applications.

Calling PythonFunction's From A VB Application Hosting Iron Python

Apr 17, 2012

I'm a C++ programming who was tapped to write a small application in Visual Basic. The application hosts an IronPython runtime and I am attempting to define some function in python and then call them from VB. I have written a simple test function in python

def test():
print "Test was Called"

Then I use the iron python to create a ScriptSource from the python file. I am able to look up the "test" variable through object operations but I can not figure out how to call the object that. For example (in VB):

pyScope = engine.CreateScope()
pySource = engine.CreateSourceFromFile("C:SomeFilepath est.py")
pySource.Execute(pyScope)

[Code]....

I am able to call the function and I see the expected output at stdout. I am still under the impression that there is some function-pointer-like type that I can cast objects of type PythonFunction to which will let me invoke temp directly without calling to the Python engine.

Calling .dll Method From Inside A Timer Won't Work(Console Application)?

Nov 26, 2009

I have a .dll file (Interop.ACTMULTILib.dll) that I use to connect to a PLC. This .dll contains a sub called ReadDeviceBlock2(byval devicename as string, byval size as integer, byref data as short). When I call this method in my main it works fine, if I call it from another method that was called by main it works as well.However, it doesn't work when I call it from my Timer_Elapsed sub? I guess this has to do something with threads but I can't figure it out.

Private PLC As New ACTMULTILib.ActEasyIF

C# - Stop Developers From Calling System.Windows.Forms.Application.DoEvents()?

Mar 15, 2009

We just spent 300 man-hours fixing a buggy application in the field. It all came down to calling Application.DoEvents (re-entrancy problem).This was not caught in design reviews, code reviews.The code was inserted two years ago with the first version; the application was always "flaky" but recent changes exposed the re-entrancy problems to a greater degree. This incident is the second time in our organization that Application.DoEvents caused failures and multi-man hours of debugging.It was discovered in this case by simply noticing the call,buried way down in a complex event handler for an asynchronous task.What do you suggest to prevent this issue from happening again:

Add checkin gates to source control?

Developer training?

Code Analysis rules (why is this not already a built-in rule?)

How to I enforce a coding practice?

.NET Application Receiving 503 Service Unavailable Error When Calling Web Service?

Apr 28, 2009

This is a bit of unusual problem that I'm experiencing, but recently one of the users of a production application started reporting errors in the system. These were traced to a 503 Service Unavailable error when making a call to a web service used by the application.

Now here's the odd part, only the one user is affected by this issue. Other users of the application have not reported any errors. When the user logged on to a different machine that worked for another user, they still received the error.

X86 Application Calling "AnyCPU" User Control

Nov 8, 2010

I'm building a UserControl which will be used by other developers.

If I build the UserControl for "AnyCPU" will there be any problems if another developer uses my UC in an application which he builds for x86.

I mean if the complete application is running on a 32 bit machine then all should be OK but if the app is running on a 64bit machine then the x86 app will run on wow64 but where does my UC run ? In native 64bit or does it default to the same as the parent ?

Or do I have to make x86 and x64 versions of my UC ?

.net - Application.Exit Raises `FormClosed` For All Open Forms From Calling Thread, Generating Invalid Thread Accesses?

Oct 31, 2010

My routine to check for updates is run as a separate process. Exiting the application is required to update, so a dialog asks the user, when an update is found, if they want to exit now. f they do, the code (from the update thread) calls Application.Exit().However, if the FormClosed event of any form that needs to be closed needs to access its controls, an invalid cross-thread operation is detected (which sounds pretty logical).

Calling .NET Dll From C++?

Aug 3, 2010

I have a C++ application exe that uses a C++ dll. I don't have the source of this C++ application and cannot rebuild it. But I know that it uses the traditional LoadLibrary and GetProcAddress to access individual functions in the dll.For some reasons, I want to replace the C++ dll with a VB.NET dll. The dll is not and ActiveX and is therefore not registered.I think I cannot use a class but a module since the C++ exe application does not expect any class in the dll. In all my attempts, I could not have the inner functions of the VB.NET to be called by the C++ exe.How should I write the VB.NET dll?

Calling C++ DLL From VB?

I'm not sure whether this is a VB forum question or a C++ question, but I'll try here first. I have an API library written in C++ (including source) which compiles to several DLLs. I want to call the functions in the library from VB but I can't get the parameter passing right.

The above example runs but returns nothing. If I change DeviceName to ByRef, I get protected memory errors.

The full library and documentation is available on the internet if anyone would like to download it and I've successfully compiled it with VS2010.
