In a C# desktop application, I am using linq to sql to connect to a sql server 2008 r2 database. The applicatiion is setup to point to various databases depending upon the value in the app.config file.
The problem is code in the *.designer.cs gets overrriden somehow by 'defaults' in the .net problem framework. When this happens the 'using system.configuration' gets removed from the application and the 'default settings' values are used to get the database connection string values.
When I notice this problem occurs, I need to do the following: 1. place the 'using system.configuration' code back into *.designer.cs file, 2. change the code so the database connection info is obtained from the app.config file, 3. remove the property settings so the 'default' database connections are not used.
Thus can you tell me what is causing this problem to occur and how to
solve the problem?

You cannot modify the designer files at all. Any code you put in there WILL be overwritten and destroyed.
The stuff your'e talking about always goes into your Form.cs files, not the designer files.
|
|
|
|
|
So what you are saying if I place the code in form.cs, then the db connection string values will not be overriden? If so, can you show me some code I can use as a reference?
|

Serisouly?? If you need this kind of help, you REALLY need to pickup a beginners book on C# and work through it.
It's no different than if you were putting the same code in the designer file.

I have the following questions in regards to converting a C# 2008 appliation that is currently executed as a dll and now I want to change the program so that is executed as an api. I have the following comments to make which are:
1. This program was originally setup as a console application, but I changed the application so that it would compile and run as a windows form application. I made the changed since I wanted to save all the output messages that were originally written to Dos popup windows to saved to log files for research and deubgging purposes.
2. This application has 4 project files. Two of the project files are class libraries and two of the project files are window form applications that I converted from a console project files to window form proejct files.
3.One of the windows form project files is the 'driver' of the application. I would like to add a 'gui' interface to the application so the user can enter data that can be utilized by the 'driver' project file.
I have the following questions I would like to ask which include the following:
1. From what I described above, would you tell me what I need to do to convert the application I listed above from being executed as a dll and execute it as api? Is there any special considerations I need to take into consideration? Can you show me code and/or point be to a reference I can utilize to accomplish my goal?
2. Would it be better to make the 'gui' interface where the user enters data a desktop or asp.net web forms application? Can you tell me why one method would be better than another method would be?

not sure I understand you fully, but, I would move/'refactor' all the non gui/console code functions etc into a dll, and export their function calls etc - this is effectively your 'api'
The dll can then be used in a console or gui program
Im not sure your point in #1 is a good enough reason to change to a windows forms app - If it were logging/catpturing output messages, you could have used log4net for example .. even if you said you wanted to capture them to a DOS type window, that can be done from log4net
[edit]
btw - your second point #2 ..'depends'  if only one user is going to be entering data and/or never from a 'remote' desktop, then maybe I'd prefer 'Forms' based - if multiple people may be entering data and you may move the solution to a more 'distributed' space, then, maybe asp.net web forms is the go ..
again, it all comes down to requirements/analysis - seperating the 'work functions' from the 'gui' type functions will help you whatever the case

An API is merely a set of classes/methods in a DLL.
1. You could just log the messages to a file (see log4net Tutorial[^]), rather than using popups.
3. If it is already a Windows forms application then you already have the GUI. Just add the controls to accept input from the user.
B1. You don't need to do anything, the API is in the DLL.
B2. Depends whether you have users that need to access it across the internet, if not then Windows.Forms is fine.
Use the best guess

Hi all, I'm a newbie to C# after learning it in AS Computing.
My Father has asked if I could create a program to find Orphaned .XMP Files.
So Here is What he would like to do:
Search for the Camera raw file first and compare it to the Directory to see if there is a .XMP file with the same name, if not then Delete the file. I know this would mean an IF statement.
I would be most grateful of any help or if someone could point me in any direction.
Kind Regards
Jonathan

Look for examples and tutorials dealing with the system.IO namespace (directoryinfo, fileinfo), these will supply the context of what you are doing. When your research has found some examples, work through them. When you come up against a specific problem come back and ask.
Never underestimate the power of human stupidity

ok .. how do you identify Camera raw files ?
To get a list of all .XMP files you can do this ..
String[] XMPFileNames = Directory.GetFiles(DirName, "*.xmp", SearchOption.AllDirectories);
Depending on your answer to 'Camera raw files', might change the way I think about the start point ...

im looking to have a console app
executing a void in my winform
how could i possibly do this
|
|
|
|
|
I think you are looking for InterProcess Communication (IPC)
|
|
|
|
|
You can host a WCF server in the console app and WinForms can act as the client.
If you are using .Net 2.0, you can consider remoting.

what i need is realy simlpe i need to call a certain void
from my app, call made by my console app
do u think that hosting a server would be good for that

i run a console app on top of a winform
i need to have my console app run a void
in my winform i call it by using this
saidvoid();
i need my console app to call that void the same way
|

That still makes no sense; what is a void? If you mean you want to call a method that exists inside a Winform then you need to use a callback method.
Use the best guess

what i do is when i click on a button it calls this
thisthinghere();
wich does this
private void thisthinghere()
messagebox.show("this message here");
i basicly need my console app to make what the button would make happen
|
|

Code in one process cannot directly call code in a completely seperate process. You have ot use some method of interprocess communication to tell the Windows Forms app to execute the method.

There are plenty of examples to get the stdoutput of a process by starting it programatically there by catching stdout of the started process, But i have hard time in getting the stdout of the process which is already running. (the situation is : There is one of my application triggers command window and as the application process some data will be printed in that command window) now using .net (winform) i need to catch that printed data.
Is there any possible solution to achieve this ? Your help/ideas will be appreciated !
Thank you.
-SSK.

You can easily capture Console output using RedirectStandardOutput[^] property.
SetOut[^] could be another option.
|
|
|
|

Yes, I can use Redirect Standardouput easily but there i need to declare a process and have to start it! (Means have to launch the process programatically) in my case the process is already started with some external action (could be manual).
If you want to simulate, You can take one simple console app and do some console.writeline to print some data...
Now, take one winform application from here try to capture the already opened console app printed data (console window). Hope this explains my situation.
Thanks.
