Could You recommend me some Internet sites containing free download electronic books devoted to :
- .NET technology (C#, ASP, ADO, Wireless/Mobile, …) , MSSQL&XML
- application mathematics – numeral methods, artificial intelligence, …
- GPS & navigation systems
Thank You !

safari.oreilly.com is a online book program, you can browse books for free, but must pay a monthly fee for your "bookshelf". They have alot on .NET, but not much on mathematics, and nothing on GPS. Is there anything specific you need to know about GPS, I've done my share of research on the topic...

Hello, I was just wondering if any of you know how to make the buttons on a toolbar have pictures in them instead of text? I'm trying to make a paint like program and I thought I would make a toolbar in which the buttons have a picture of the drawing tool you can use ie. pencil.

Remoting. It's the only way since handles aren't valid across application boundaries.

Hi all,
I have an xml file with a structure similar to the following
<Main>
<Child id=somename>
<Grandchild>
</Grandchild>
...
...
<Grandchild>
</Grandchild>
</Child>
....
....
<Child id=somename>
<Grandchild>
</Grandchild>
...
...
<Grandchild>
</Grandchild>
</Child>
</Main>
I want to rearrange the <Child> elements programmatically. can i do this with something in System.Xml namespace. I am new in using xml files in C#.
Any help is greatly appreciated.

An XSL sheet will allow you to reorganise the sheet, so long as you can define the sort criteria easily. Otherwise, you could create a new document and shove them in in the order you want them.

thanks for the reply but I would like to do it programmatically. I will be given two node id's and i want to be able to exchange them, meaning interchange their position in the xml document.

Well, using XSL or creating a new document *would* be doing it programatically. How else would it be ?

Well, you can't. Sorry. The DOM does not allow for it, unless you pull them out and stuff them back in. That's what XSL is for, I just gave the other option in case you did not know XSL.

Is there a way for getting a command line options for C# compiler (csc.exe) from Visual Studio .NET 2002 project?
I need it to compile my project using .NET Framework 1.1 (since VS.NET 2002 doesn't support it and I don't have money for 2003 one).
It would be ok if my project has about 2-3 source files .. but it has about 80 source files and writing it down by hand is not very practical.
Thanx

well .. that's nice 
But the code is also structured into folders ... anyway, I have already written an utility for generating commnad line for csc.

I want to have the possibility to enter a math algebric expression (e.g. z=sin(x*y-1)+x/y-2*x) and values for the variables (e.g. x=2.1, y=0.2) during execution of my program in WINDOWS environment.
Is that possible?

I'm strating a CCW object on a server side. How can I get a full path to dll file in one of the CCW methods?
Thanks,
vital.

You mean, so that unmanaged code can get the path of the .NET control via it's CCW that the runtime created? One way is to have a COM-callable method (declared in your class interface) that returns it's own path (perhaps using this.GetType().Assembly.Location. Getting the path through native COM functions can be a bit tricky.

Hello.
Help, please.
I'm trying to call a CCW object from an asp file. I registered a CCW with regasm.exe and then installed with gacutil.exe.
So, in asp is written:
try
{
objCheck = Server.CreateObject(rstData.Fields("LibName").Value);
blnAllowed = (objCheck.Permissions() & 0x01 != 0);
}
catch(e)
{
%>
/*
// LibName: <%=rstData.Fields("LibName").Value%>
// ERROR: <%=e.description%>
*/
<%
blnAllowed = false;
}
And I get an error:
// LibName: OilMiningBalance.Rep_Struct
// ERROR: Object reference not set to an instance of an object.
The name of CCW is correct, but then what's the matter with it?

The error is stating you are trying to access a variable/object that you haven't declared yet. Try declaring objCheck before calling Server.CreateObject.

objCheck is declared as follows:
var strSQL, rstData, objCheck, blnAllowed;
strSQL = "SELECT Id, LibName, ShowProhibited" +
" FROM PrintDoc";
rstData = dbConf.Execute(strSQL);
, but it isn't working yet.

How do we associate a file type with an application.
Plus how do we add our own items to the context menu ( not in the application)?
Like winzip ..when u right click a folder it provides the option of zipping...
how do we do that for our application??
|
|
|
|

I believe creating an .MSI setup project will allow you to do associate file types. MSDN has lots of information on this.
Adding custom items to the sytem context menu will probably require some registry modification. Search this forum or google, I'm sure it has come up in the past.
The graveyards are filled with indispensible men.

While MSI does allow you to create those (like the other poster stated), you don't have to use that. Even then, you must still add the file type associations to the package project.
You should first understand how these are done, because you could even have your application do this the first time it starts up, or even ensure that it owns the association (but you should ask the user for such an option, sort of like Windows Media Player, QuickTime, and RealOne do). See the MSDN article, Introduction to File Associations[^], for more information.

I have a framework that allows me to create a wizard, by dynamically loading controls. I've found a similar framework on the web, in VB.NET. Mine is successfull at maintaining viewstate in the postback, so I can store/renew the data. The other one stores data in session state (yuck), but also maintains viewstate. This other one, however, can catch click messages in user controls that are dynamically loaded ( so I have a user control for the wizard, it shows user controls for pages, and a page contains a user control, with a button/click event ). I converted it from VB to C#, and now it does not catch click events either. Is this a bug in the C# implimentation, or am I missing something else ? I've tried to impliment IPostBackHandleEvent and it does not get called, I've tried assigning my click event in the ascx and in code. I have worked on it all weekend, and am now desperate and very sad.
