Typically, this is caused by an application being compiled to target "Any CPU". This means that the code will run as a 32-bit app on 32-bit Windows and as a 64-bit app on 64-bit Windows. The problem comes in when the app uses 32-bit only components and .DLL's. You cannot mix 32 and 64-bit code in the same process, so an app that works fine as 32-bit will fall on it's face when run as 64-bit using the exact same components.
The solution is to recompile the app to target x86 only, but you need the source code for that.
The other fix is to run it on 32-bit Windows only, be it in a virtual machine or rebuilding the customers machine to run 32-bit Windows instead, but customers tend to frown upon this.

You can make an "AnyCPU" .NET app to run in 32-bit mode without need to recompile it.

HI,
What information is seen when the details button on the Unhandled exception dialog is clicked. The exception type and a stack trace should be available even if the application was built in release mode with debug information set to none.
Ask your clients to
1) highlight the detailed information by dragging over it with the mouse
2) Press Ctrl-C to copy the highlighted text to the clipboard
3) Paste into Notepad
4) Send you the file.
Alan.

I don't know if I'm on the right message board but I could at least give it a shot...
I'm testing with NUnit. The code itself has been written in Microsoft Visual Web Developer 2008 Express Edition. I need to debug a test. Therefore I have set a breakpoint to start step-by-step debugging at a certain point.
However, NUnit skips the breakpints and runs the test all the way throught at once. How can I make NUnit pause at the breakpoints so I can do some step-by-step debugging?
Thanks in advance!

Dear All,
I have an application which will be deployed by clickOnce,
I have a Service Project in the same project, I want that when Installing the Application via the URL the service should be installed in Client Computer, as the application is avilable both Online and Offline.
any ideas, Like is it Possible to deploy the Application and Install the service via Click Once Deployment?

Pls i want to access the private methods and events of a MDIChild Form from its parent Form and execute them, I do not know the how.
Thanks.

Firstly: you shouldn't do it. If method is to be called from outside of the class, it should be public, not private. And that's the path you should follow.
The backdoor to access private methods and fields is reflection (but it's bad). But I think you can solve your issue by changing methods' access to public.

Hi,
I am new to multithreading, and I am considering implementing multithreading in my code.
I am using MDI application with two child forms. On first child form I have all the controls and user interface (ChildForm1).
Second child form is used for data analisys and drawing graphs (ChildForm2).
ChildForm1 implements:
1) serial port communication (communication with microprocessor on PCB board)
2) data acquisition from intrument connected to computer (LAN) (up to 200ms for each data acquisition)
3) data processing and controls
Currently I am using timer control to comminicate over serial port (10 times per second - checking the conditions), triggering
data acquisition (when conditions are met) and finaly processing data and drawing graphs on another child form (real time).
As I use single thread, I am experiencing some delays (application not running smoothly as it waits for comm process and data processing).
What would be the right approach in setting multithread application ?

Hi,
There basically are two schemes you have to choose from.
1.
if the timer is a Windows.Forms.Timer and your Tick handler is short (less than 10 msec), then everything should be OK. That requires there are no blocking I/O methods called. So when your peripheral needs 200 msec to perform a data acquisition, it would only work smoothly if that gets handled asynchronously, i.e. in one timer tick you issue a "start acquisition" command without waiting for the results; and in a different handler (or a later tick of the timer) you issue a "now deliver the available data" command.
2.
If the above is not possible, the alternative is to have a second thread that takes care of communicating with your peripheral and preparing the new data; it should then use the Control.InvokeRequired/Invoke pattern to update the GUI. See this little article[^].

Hi!
I am making a setup installer(windows installer) which will install my application .I require a serial number window to integrate. I am using the "Customer information" window of setup project. There is an option of serial number entry. But the problem is i cant change the algo of validate serial key. the in-built algo is too week. Please help me, tell me how i can integrate serial number in "setup.msi"
Thanks!

Hi all,
Apart from saving setting of app in DB , what are other option which one can use.
I know few like saving in registry, file.
But applications like ccleaner, and some small utilities, dont think they save it in registry, or file. As in their program files directory there present no file.
So ,How they able to save settings ?
a) How they achieve this?
b) Is there a way by which i can embed my DB file inside .exe/.dll file.
Regards
|

I don't know for sure how does ccleaner do it, but I suppose it saves it in file located in your user profile. On Windows XP it would be somewhere in "C:\Documents and Settings\%user name%\ApplicationData" (I don't remember exact path and I don't have XP to check  ). In Vista and 7 it's somewhere in "C:\Users\%user name%\AppData". Take a look at this[^]. It provides you with paths, where you can store settings for every user. You should use "Environment.SpecialFolder.ApplicationData" probably and create there subdirectory for your application. This way you will be able to store settings for every user. When those settings are stored in application directory, they are common for all users and when one user changes something, all users are affected. And why write code to support multiple users, when system does it for you

As for your b) question:
Yes, you can embed your database in the executable. I got this using Google ("c# embed file in executable"), and it looks pretty good:
http://www.cs.nyu.edu/~vs667/articles/embed_executable_tutorial/[^]
However, I don't know of any database system that will let you USE the database WHILE it is embedded, so once your program is installed and you need to use the database, you will need to extract it...

|

I create my own configuration files; XML, generally in either the user's or all users' application data directory.
Even if most of the configuration is in a database I still need a configuration file to tell the application how to connect to the database.

I am read plots from serial port and draw it ....
I have problem with flickers ...and use DoubleBuffer property to solve the problem ... but flickers increase rather than the first .... what i should to solve problem ....
what is the best design for Application to smooth drawing ?
|
|
|
|

flickering typically means your paint job takes too long (say more than 10 msec), so it becomes visible to the human eye. Depending on what you have done several steps can be taken to improve it, maybe by a lot. Please explain more, and/or show the relevant code or pseudo-code.

I am make method read data from serial port and check plot if it valid or not regarding as some specifications ... if it valid i catch it and store message in arraylist and then read from arraylist to draw plots.

That is completely insufficient to judge whether you will have a painting problem or not.
There are a few categories:
1. Throughput
How many bytes do you need from your serial port to complete a drawing? what is the baud rate? is the peripheral sending full throttle, or does it need extra time to generate the data?
2. Plot
What do you need for plotting? is it some library that takes data points and generates an image, which you then paint? which library? how many data points? how big is the bitmap?
3. Organization
How do you structure this? Are you using the DataReceived event? if so, how and when do you transfer control to the GUI thread for painting.
Are you painting in the Paint handler?
Feel free to provide extra information if you think it may be relevant.
PS: take your time, I'm off now.
