Identities are evil, they cause nothing but trouble like you're experiencing now, don't use them.

1) Format your code snippets using the "code block" toolbar item

A simple way would be to have another query with the field order reversed.

This should work. I've just tried it and it seemed to do exactly what you wanted.

dataGridView1.RightToLeft = System.Windows.Forms.RightToLeft.Yes;

I searched a lot on WEB but unfortunately not able to find any resource which can help me with this.

I will be thankful to you all for any suggestions and pointers.

Thanks

Why Control.FromHandle(IntPtr) returns null in one hooked process and returns valid object of “Form”? in another hooked process?

glitteringsound29-Jun-11 3:13

29-Jun-11 3:13

I am facing a problem related to get out all the controls from some hooked process. My SpyDll launched into hooked process sucessfully, But when I check the statement

Control control = Control.FromHandle(MainWindowHandle), it returns null into control object where "MainWindowhandle"is just a native main window handle of that hooked process, which you always take from .NET "Process" class after launching that process.

But STRANGLY it happens that in some other hooked process which is the same C# .NET application, it returns valid object of Main "WinForm".

So why it will not work in above case? Are there any exceptions to use "MainWindowHandle" properly. In my case both are seperate .NET managed processes programmed in C#. Any process configuration needs to maintain specially while creating that process?

This could be a timeout, because the server application needs too long for its answer. It could also be a sporadic network problem which your client application doesn't handle. But your question is too incomplete to give a better answer.

This statement is false.

Activator.CreateInstance

Hello.

Am not sure about this, hope someone can provide a little help.

I've got a folder with a variety of pre-defined Crystal Reports which will need to be instantiated depending on some user input. This folder is not part of the solution, it's just sitting on a server drive.

So assuming the input is rptTest, I need to instantiate the report called rptTest. If the app can't find a match, it alerts the user.

Is it Activator.CreateInstance I need to accomplish this or is it simply not possible? If it is, can anyone provide a code sample. I know I need an assemblyname and a typename for one but which would be the user input and what would the other be?

Hope I'm being clear and that someone can help.

Thanks in advance

Activator.CreateInstance is used to create instances of C#/.Net types at runtime. This allows you to switch which class gets created based on runtime information (user input or information provided by virtual methods, for example).

abstract class A {}
class B : A {}
class C : A {}

A CreateSomething(string classname){
 return Activator.CreateInstance(Type.GetType(classname));
}

A CreateSomethingOfTheSameType(A template){
 return Activator.CreateInstance(template.GetType());
}

I don't believe Crystal Reports are saved as .Net classes and thus this won't be the correct approach. I would imagine that Crystal allows you to load reports from file.

Here's what I use:

...
            CrystalDecisions.CrystalReports.Engine.ReportDocument crRpt = 
                new CrystalDecisions.CrystalReports.Engine.ReportDocument() ;
            crRpt.Load ( Defile.FullName ) ;

Thanks for the answers guys, much appreciated.

Just one more thing, is there a way I can instantiate a custom dataset on the fly as well. Similar to the crystal reports, I've another folder which contains XSDs to use as the datasources for the reports. Could they also be generated according to user input?

Thanks again for your help so far.

Re: Activator.CreateInstance

BobJanova28-Jun-11 22:29

You can construct a DataSet manually at runtime (adding tables, columns, rows etc), or you can use DataSet.ReadXml.

You, Sir, are a very good man.

I forgot totally about calling the ReadXml method, saves me from having to turn everything into an XSD and can simply populate the crystal report using it instead.

Bob for President.
