In case anyone else is having the same problem, I figured it out. Of course it was simple. Instead of using the sqlDataAdapter.Fill(dataset) like in the previous walkthroughs, I had to use sqlDataAdapter.Fill(dataset, "tableName")

You can also set up the SqlDataAdapter.TableMappings so that "Table", "Table1", "Table2", etc. get mapped to your actual tables names. The generated table names are in the order of the tables in the result set if your expression, view, or stored proc were to return multiple result sets.

If you want to do this at install time, use a ServiceInstaller and ServiceProcessInstaller which allow you to set the logon account when a service is installed using installutil.exe or the AssemblyInstaller in your own code.

If you want to do this at runtime, you'll need to P/Invoke ChangeServiceConfig like in the following example:

[DllImport("advapi32.dll", CharSet=CharSet.Auto)]
static extern bool ChangeServiceControl(
  IntPtr hService,
  uint dwServiceType,
  uint dwStartType,
  uint dwErrorControl,
  string lpBinaryPathName,
  string lpLoadOrderGroup,
  ref uint lpdwTagId,
  string lpDependencies,
  string lpServiceStartName,
  string lpPassword,
  string lpDisplayName
);

To get the hService handle, you'll need to also P/Invoke OpenService or CreateService. The ServiceController does most of what you need but not in this case, so you're probably better off writing your own class to handle that. I would recommend using the dispose pattern to make sure that any handle you open using OpenService or CreateService is closed using CloseServiceHandle.

Read Service Functions[^] for more information.

Hello,

Unfortunately i did not find a good sample so i develop a login-screen on my own. The course of the events in my application is the following: When the the user logs in some a new form is showed where some user specific information is displayed. The problem can i know in the new form which user with wich userid was logged in?? - Is this possible with taken over a parameter form the login-screen to the other form? if yes how does it work in mobile applications?

Regards

setting datagrid cursors

ddelapasse6-Oct-04 4:01

6-Oct-04 4:01

Hi,

The ONLY way I can find to change a bound datagrid's cursor look successfully is to subclass DataGrid and inside the OnMouseMove force the cursor. However, because of some black magic we are using to force row heights on a particular grid I am NOT allowed to subclass it.

Are there any other ways I can force the cursor? Our requirements insist on a 'hand' cursor for all our grids containing selectable items.

thanks,
Deanna

.NET OLAP control?

I am looking for an OLAP control. So far i found two ActiveX controls:
- DynamiCube
- ContourCube

I like the functionality of both controls, but the controls do not support the XP visual styles. Also i prefer a .NET component above the ActiveX controls.

Is such an OLAP control available?

That's correct. Only these two are OLAP charts. What i need is an OLAP table with multiple dimensions on both the x and y axis.

serialization problem

Hi I have simple class

[Serializable]<br />
	public class Siren	: IDataSourceItem<br />
	{<br />
		uint		        _id;<br />
		string			_Name;<br />
		int			_InventoryNumber;<br />
		string			_SirenType;<br />
		string			_LocationStreet;<br />
		string			_LocationNumber;<br />
		string			_Remark;<br />
		DateTime		_LastDiagnostic;<br />
		DateTime		_NextDiagnostics;<br />
        .<br />
        .<br />
        .<br />
        .<br />
        .<br />
        .<br />
        }

and I have collection of classes of this type

[Serializable]<br />
	public class SirenGroup :  System.Collections.CollectionBase,IDataSourceItem<br />
	{<br />
		public SirenGroup(){}<br />
<br />
		public int Add(Siren siren)<br />
		{<br />
			return this.InnerList.Add(siren);<br />
		}<br />
<br />
		public void Insert(int index,Siren siren)<br />
		{<br />
			InnerList.Insert(index,siren);<br />
		}<br />
<br />
		public void Remove(Siren siren)<br />
		{<br />
			InnerList.Remove(siren);<br />
		}<br />
<br />
		public new void RemoveAt(int index)<br />
		{<br />
			InnerList.RemoveAt(index);<br />
		}<br />
         .<br />
         .<br />
         .<br />
         }

when I serialize this object evrything seems OK

BinaryFormatter binaryFormatter = new BinaryFormatter();<br />
   System.IO.MemoryStream memoryStream = new System.IO.MemoryStream(100);<br />
   <br />
			   <br />
   try<br />
   {<br />
	binaryFormatter.Serialize(memoryStream,sirenGroup);<br />
   }<br />
   catch (System.IO.IOException exc)<br />
   {<br />
	Utilities.WriteLog.WriteError(exc);<br />
   }

when I deserialize it

try<br />
{<br />
   System.Type typeObjectType = typeof(Definitions.SirenGroup) ;<br />
  if(typeObjectType.IsSerializable)<br />
  object sirenGroup = <br />
            System.Convert.ChangeType(binaryFormatter.Deserialize(memoryStream),typeObjectType);<br />
}<br />
catch (System.Runtime.Serialization.SerializationException exc)<br />
{<br />
	Utilities.WriteLog.WriteError(exc);<br />
}

I get an error : stream ended before analysis was finished
Could anybody please tell me wat can produce this error.
Thank You

Salut!

If you're doing that all in one go you're going to have to set the MemoryStream's "Position" property back to zero before trying to deserialize.

Also, the use of ChangeType is not necessary as you should be able to cast it directly like so:

Definitions.Sirengroup sirenGroup = (Definitions.SirenGroup)binaryFormatter.Deserialize(memoryStream);

Convert base64String to byte[] in CrystalReport

Hi all,
I'm currently trying to use an xml-file as datasource for CrystalReports.

Works fine so far, but unfortunately Crystalreports displays the image, which is in the xml-file as base64String, as string.

Is there something like the Convert.FromBase64String() method in Crystalreports, so that my image is actually shown as an image?

Best Regards
Bernd

I haven't done any convertions in Crystal Reports but I would recomend using an ADO.NET as a data source. You can load a dataset from your XML file and pass it into the report

Hi,

Does any one know to pop up a GUI from a windows service? The windows service I am developing uses process to execute exes(another applications). Some of those exes may have user interface. Since the exe's are being executed from a windows service, the user interface of that is not displaying.

Thanks,
Jo.

If you look at the service in the control panel you should find an option that allows the service to interact with the desktop. It should be under the logon tab.

One method of using C# class or a C# dll is to wrap the C# code as a COM object that you can then use in another language. Here is a link to an article on that.

Height of Font

sachinkalse5-Oct-04 22:32

5-Oct-04 22:32

Font.GetHeight Method and Font.Height Property are being described in almost identical words in MSDN.
If I test both the font size = 11
The GetHeight return 14.66667 and
Height Property returns 15Font.
What is the difference between two values?
please guide

Re: Height of Font

Christian Wikander5-Oct-04 22:45

Christian Wikander

The difference is described in the documentation for Font.Height in MSDN.

GetHeight is returning a float and Height is an int. GetHeight is returning the exact height and Height is GetHeight rounded upwards.
