I've never had a need to use conditional compilation before, so I have very little experience with it. Is there a way to do your #define directivess in a single place?

I want to set 2 define variables, and include certain menu items in the presents of each. (different features allowed in different editions of the same project). But I would like to avoid having my #define directives in the designer file where the autogenerated code is and the forms code file where the event handlers are. Is there a way to do this? I know this approach has other problems as well, any changes that alter the designer file will toss my changes to the wind for one thing.

If not I can of course build and add my menu items manually outside of the designer file, but it would be nice to have them there at design time too.

In the properties for the project. Right-click the project in the solution explorer. Click Properties from the menu. In the new window that opened up select the "Build" tab and look for "Conditional Compilation Symbols"

You can't put them in there anyway - Visual Studio will overwrite them.

You could put them in the form's load and have it remove the UI elements you don't want if you want the menu items available at design time.

Yeah, I know. I was looking at loading them after startup. But then I have ordering issues. Removing them on load is a good idea. And I never noticed the conditional section in the project properties. Thanks.

Hi,

you dont need to include #define statements at all, you can define symbols in the
project properties dialog, under Build/General/Conditional Compilation Symbols.

That is what I do when I run two different projects (one .NET 1.1, one .NET 2.0)
on the same source files, to make sure my code works for both; doing so I can compensate
for slight differences between both .NET versions (e.g. method name changes in Dns class).

So I suggest you use Designer to set up your project in one way, then add #if #endif blocks
to modify it in your code files (e.g. after InitializeComponents) for the alternative way;
now change your defines manually in the property dialog; you could even add configurations
(say multiple debug configurations with different #defines).

Smile | :)

Actually, I'm thinking about having different project files for each edition while keeping the same code. In this situation, it seems a more reasonable approach than moving shared functionality to a control library. Thanks for the suggestion.

Probabaly need to see your code, but it is a really bad idea to use a static var in global.asax. If you have an application wide varible you should use the application object, it is just like session. It can be set in an event in the global.asax or anywhere else for that matter. If the var is supose to be user specific then you need to use the session object.

Hi
Thanks for the reply.Here is the part of my code.

XMLCacheComm = new XMLCacheComm();
In Application_Start of global asax page
Application["XMLCacheComm"] = XMLCacheComm;

and in constructor XMLSportsIn() of webservice written as
XMLCacheComm XMLCacheComm1 = Application["XMLCacheComm"] as XMLCacheComm;

and in a method of webservice,when i call
XMLCacheComm1.SendMessage()..here i am getting object reference not set to an instance of an object

Any idea

Regards

When you create it in the application_start you have to assign it a variable
XMLCacheComm _xmlCacheComm= new XMLCacheComm();
In Application_Start of global asax page
Application["XMLCacheComm"] = _xmlCacheComm;

This line:
XMLCacheComm XMLCacheComm1 = Application["XMLCacheComm"] as XMLCacheComm;

You might want to double check to see if the item is there. Something like:
if (Application["XMLCacheComm"] != null)
{
XMLCacheComm XMLCacheComm1 = Application["XMLCacheComm"] as XMLCacheComm;
}
else
{
XMLCacheComm _xmlCacheComm= new XMLCacheComm();
Application["XMLCacheComm"] = _xmlCacheComm;
}

Hope that helps.

I am not that familar with the XMLCacheComm object, so I am not sure what the Count property refers to. So I am not sure why the count would be 1 or 2.

Accessing Control on my webpage

Hi,

I have a web page C#, written and working.
I now need to see and validate certain controls on my page beginning with 'dt'.

In VS2005 i can happily type ...

foreach (Control ctrl in MyPage.Controls ) and it would list them and then I can use them

This doesn't work in VS2003. Any suggestions welcome?

My guess would be that you don't have a page called MyPage in VS2003.

foreach (Control c in Page.FindControl("MyPage").Controls)

no, the C# (or C or C++ or Java) language does not have special keywords for input/
output. They rely on classes to do your I/O. See for instance SerialPort, Graphics,
File (and all the stream stuff) etc.

Yes, I hope he was refering to such things as the good old IN and OUT statements in Basic
(and the corresponding assembly instructions available on several microprocessors).

Thanks for the reply, but the article only provides a panel and a progressbar. Although they're really nice, what I'm looking for is to change the colors in the title bar of my child windows: In Window's classic theme they're set to the colors defined in the selected theme (blue and lightblue by default).
