C# - Stop Developers From Calling System.Windows.Forms.Application.DoEvents()?
Mar 15, 2009We 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?

VS 2008 Launching Default Application From 2008 Under Windows 7
Nov 5, 2009Within my application we store objects i.e images,word docs, etc etc. These are stored in a listview and when the user double clicks the item it launches the default application assigned to the file type i.e a bmp will launch paint, doc will launch word etc etc.
Everything works great in all versions of windows except the new Windows 7 where i am getting this error message:
Im guessing this is something to do with permissions etc, but can anybody shed more light on this and where to look?
Calling A DLL From .NET - Error Occurs On Windows 7?
Feb 8, 2012I have a VB6 DLL that wraps a call to a 3rd party component. When I call my DLL from VB6, everything works fine, but when I call it from vb.net (2.0 framework targeted - VS2010) I get this error:
AccessViolationException occurred
Attempted to read or write protected memory. This is often an indication that other memory is corrupt.This error only occurs on Windows 7 (Windows XP clients work fine).I've looked this up and all the articles I found talked about the declaration not being correct.I am not declaring any APIs calls though, the 3rd party component is early bound in my VB6 DLL.I can run the DLL, set a breakpoint,and it goes into my VB6 function, but errors calling a function in the 3rd party component.My VB6 DLL takes 3 string and one 32bit numeric (long in VB6) parameters. The 3rd party's DLL function that I am calling is taking a string (bstrDNSID as string is what Intellisense shows in VB6). This is where it errors.
Update: None of the marshalling has helped, so I tried creating a test sub in my VB6 DLL. I hardcoded all the values within the DLL's test sub. It works fine when called from VB6, but gives the same error as above when running from .NET. Also of interest, when I have the VB6 DLL running from the VB6 IDE, I do not get the error when calling the DLL from .NET.
Interop - Calling Windows SDK GetGlyphIndices From .Net?
Aug 19, 2009I am calling GetGlyphIndices from Vb.Net. I am using a single character string. I get the correct value in the indices array for the character '6' but not for characters requiring 2 bytes to be returned.
Does anyone have any experience with this API call? My next step is to write the C equivalent and make sure I can get it working without interop.

Apr 15, 2012So im just wondering, in batch they have a default way of saying the original drive or folderpath like so: %drive% for your C: drive or whatever your drive is or like %windir% for the windows directory.

View 1 Replies.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, 2010I 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. We want same behaviour but want to run fortran exe from .net application, If we click on button in vb.net form, this exe should get called and should show inputs to enter on the command line, once inputs entered it should execute. 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]
View 1 RepliesCalling Another Application From Within A VB Program?
Feb 9, 2011I 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.
