It seems like such a newbie question. I added the 'reference' to the C# project to the C++ project. And added the CSServer::CSServer::Enter_CSServer() for the call. But I get 'CSServer is not a class or namespace name', as well as the Enter_CSServer is not found.
Is there any way you could put this simple sample with .sln file together so it compiles? Seems like such a simple problem but I don't see it.

Apart from the missing namespace and class name the whole thing won't compile because the callback isn't defined either.
Remove the call to Do_Callback(), then you should be able to compile the C# class library at least.
After this you should add a reference in your C++ project to the C# class library and, by using the fully qualified name including namespace, be able to call the static function.

Already did that. The C# compiles just fine. But then the C++ does not find the namespace.
I tried adding the using namespace CSServer; to the C++ code, it errors out.
I tried adding a #using <testmix.dll> and it finds the .dll but no change on compile.
I tried adding a namespace CSServer; to C++ code and the intelisense finds the _tmain and do_call_back entry points for CSServer::[intelisense here] but not the CSServer class.
I tried making sure everything has the same namespace but looks like C++ does not have a 'default' namespace.
It's probably just some simple setting I'm missing (I suspect on the C# side) but I sure don't see it.
I appreciate your help btw.

How to modify the location of a dynamically created control in a asp.net page using c#?
|
|
|
|
|
The ASP.NET forum will help you will ,i think.
|
|
|
|
|
Actually i tried transforming the region of the control to a rotation...
for example,
Region reg = new Region();
Matrix matObj = new Matrix();
matObj.RotateAt(/*some angle*/, /*with respect to some point*/);
reg.Transform(matobj);
myControl.Region = reg;
Iam able to attain the rotation...but supposing the region (reg in this example)is in another shape(than rectangle)...say ellipse, then the shape of the ellipse is not visible completely....reason is that the rectangle coordinates(i.e. the original rectangle size) used to draw the ellipse is smaller than the rotated structure...(after rotation, the location of points are actually out of the bounds of the controls client rectangle...)
So i tried to get the size of the outer rectangle which has completely both the original and the rotated rectangles... by some trignometry...
but nope, im not getting the exact coordinates...
can you help me in this??
Thanks and Regards,
Rajesh

A good idea would be to load the contents of your XML file into a dataSet and do your searching on the dataSet instead. This gives you the advantage of handling XML data as if it was an ordinary Database.

string strPath = Server.MapPath("../CheckList/") + "TempFile.xml";
ImportXML(strPath);
}
}
can u help me in another way to do this?

Load data from the XML document into a dataSet:
<code>ds</code>= new DataSet();
ds.ReadXml(fileName);
Create a new row based on the table of the dataSet
DataRow <code>drs</code>= ds.Tables["Table1"].NewRow();
drs["Message"] = "Hello World!"
ds.Tables[table].Rows.Add(drs);
Delete an existing row from the table
if (ds.Tables["Table1"].Rows.Count > 0)
{
ds.Tables[table].Rows.RemoveAt(this.dataGrid1.CurrentCell.RowNumber);
}
Search for a value
if (ds.Tables["Table1"].Rows.Count == 1)
if (ds.Tables["Table1"].Rows[0][ds.Tables["Table1"].Columns[0]].ToString() == "Hello World!")
MessageBox.Show("Found");
Save the changes to the XML file
ds.WriteXml(fileName);
Hope this will help you get the picture.

Thanx polis,
but can u tell about the ImportNodes method in the XML api?
|
|

|

ImportNodes method? Hmm... I am not aware of this one Shankar, sorry. XML API? What exactly do you mean by this?

In the System.XML namespace , we have a class called XMLDocument.
If we create an object for the above said class, we can call the ImportNodes method.
It's working correctly. but i need to know the correct usage for importnodes method.
|

Oh right. I just had a quick read on the MSDN[^]about the ImportNode() method. Well, it seems that all it does is to import specified XML nodes from another XML file into the one you are working with.
E.g.
XML File #1 (Current XML file you work with)
Nodes: FirstName, LastName, Age
XML File #2
Nodes: FirstName, LastName, Age, Address
By saying something like "....ImportNode(doc2.DocumentElement.LastChild, true);", it will append the Address node into your XML file #1.

Hi,
I need to Convert XML file into CSV file format
Pls forwad me the code for that in C# or vb,net
Regards,
sanjeev

I don't know about others, but I can only guide you to the right direction. I don't think that asking for the complete source code is a good idea.
I would:
1. Load the XML file into a table in a dataSet
2. Construct a new file on the disk giving it the extension .CSV
3. Loop through that table and copy each of its records into a new line of a text file by comma separating each column's content.
4. Save the file (close File streams)
5. Destroy dataSet
6. That's it
Hope this helps

Since Ms Excel can automatically load CSV files why don't you convert your XML file into a CSV one instead? (Now that I think about it, doesn't it load XML files automatically as well?)
Anyways, if you do decide to convert your XML file into a CSV one, take a look at these steps as they were suggested on the previous post:
1. Load the XML file into a table in a dataSet
2. Construct a new file on the disk giving it the extension .CSV
3. Loop through that table and copy each of its records into a new line of a text file by comma separating each column's content.
4. Save the file (close File streams)
5. Destroy dataSet
6. That's it
Hope this helps
