See this post for the fix. If you don't want the user to be able to move the window, then set the FormBorderStyle to FormBorderStyle.None;

I have this program in which I'm adding TraceSwitches to various subsystems. I got it working fine in one subsystem - so I went ahead and added it to other subsystems. When I try to enable with other switched using my config file - the original switch now throws an XML exception (at the first call to WriteLineIf(), not when newing the TraceSwitch ).

Here are my config files:

The one that works:

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
<system.diagnostics>
<switches>
<add name="FirstSwitch" value="4" />
</switches>
</system.diagnostics>
</configuration>

The one that blows up:

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
<system.diagnostics>
<switches>
<add name="FirstSwitch" value="4" />
<add name="SecondSwitch" value="4" />
<add name="ThirdSwitch" value="4" />
</switches>
</system.diagnostics>
</configuration>

Any ideas what's wrong with the syntax or how to enable multiple switches with a config file?

Thanks

Hi All,

I am trying to view some Reports online through my Internet site.
I am using C# on a Windows 2000 server running IIS5.

I have looked around the internet and found some examples but they are not working. I have the following at the moment.

<cr:CrystalReportViewer
 id=CrystalReportViewer1 
 style="Z-INDEX: 101; LEFT: 8px; POSITION: absolute; TOP: 6px" 
 runat="server" 
 ReportSource='<%# "C:\Inetpub\wwwroot\Outbreak\Reports\test.rpt" %>' 
 Height="1133px" 
 Width="1030px">
</cr:CrystalReportViewer>

In design view I cn now see my report, but when I compile and view my page I get

CS1009: Unrecognized escape sequence

????

Can someone let me know where I am going wrong and how to sort this out.

Thanks,
Gavin

it's the back slashes in your ReportSource string.
why do you have it as a server side string???
change it to:
ReportSource='C:\Inetpub\wwwroot\Outbreak\Reports\test.rpt'

It was set as a server side string because that is how the Crystal Report Viewer set it itself.

What I did was I dragged the CrystalReportViewer off the toolbox and dropped it onto my form.
I then selected it and in the properties window click on the ... next to databindings.
I then went into the ReportSource and put in the exact Source and clicked ok and it did the rest Smile | :)

...

I changed it as you suggested and am now getting the following error.

Cannot create an object of type 'System.Object' from its string representation 'C:\Inetpub\wwwroot\Outbreak\Reports\test.rpt' for the 'ReportSource' property

I'm sure this is meant to be a lot simpler than it has turned out to be?

Thanks for the help

ok, so try this:
ReportSource='<%# "C:\\Inetpub\\wwwroot\\Outbreak\\Reports\\test.rpt" %>'
or:
ReportSource='<%# @"C:\Inetpub\wwwroot\Outbreak\Reports\test.rpt" %>'

Okay well that has solved the invalid escape sequence thingie, BUT Smile | :)

now I am getting the following error

Source Error: 

An unhandled exception was generated during the execution of the current web request. Information regarding the origin and location of the exception can be identified using the exception stack trace below.  

Stack Trace: 

[NullReferenceException: Object reference not set to an instance of an object.]

   System.Web.UI.Control.InitRecursive(Control namingContainer) +179
   System.Web.UI.Page.ProcessRequestMain() +169

Would this be a problem with the actual report (which seems to work fine of opened in Crystal) or is it still a coding error?

Thanks

28-Apr-02 19:40

I waana define some Column style for my datagrid somewhere in my codes,I use this code:

DataGridColumnStyle GridSeqStyle;
DGStyle = new DataGridTableStyle();
     
DGStyle.MappingName = "FS";
 
PropertyDescriptorCollection pcol = this.BindingContext[myDataSet, "FS"].GetItemProperties();


GridSeqStyle = new DataGridColumnStyle(pcol["FS"]);
GridSeqStyle.MappingName = "SeqNo";
GridSeqStyle.HeaderText = "Sequence No";
GridSeqStyle.Width = 100;
DGStyle.GridColumnStyles.Add(GridSeqStyle);

But I get this error:
Cannot create an instance of the abstract class or interface 'System.Windows.Forms.DataGridColumnStyle'

for this line:----->GridSeqStyle = new DataGridColumnStyle(pcol["FS"]);

Any Suggestion?

Web services and c#

ez228-Apr-02 10:59

28-Apr-02 10:59

I not sure which is the best forum to place this question in so I will start here.

I have an web application that has a business logic layer consisting of serveral files in c#. I want to expose some of those methods in the files via a web service. I belive I can expose them using the [WebMethod] attribute. Now, I can also generate an asmx (web service)file for the web services but I can not for the life of me figure out how the asmx file is supposed to find out about the webmethods in the business logic layer.
Any suggestions.

I can easily create an asmx file and write the code directly into the file but that defeats the purpose (i.e. now I have the same logic in two places) Please any help would be great.

The .asmx can be created in VS.NET where you can create a Web Service. The beauty in this is that you should also be able to allow VS.NET to create the wdsl portion, which exposes the methods available through the web services. Take a look at the wsdl that Chris has created for the XML web service that is up and running now. Code Project WSDL Contents

Hi Nick,

Yes I understand that and have been able to do just that. My question is how does one create a web service (asmx file) that supports multiple classes in different .cs files? When creating an asmx file, you can associate a codebehind page but it seems to be able to support only one .cs file and one class. I want the codebehind page to show multiple cs files and multiple classes. (Does this make sense?) Can this be done?

I might be missing something here so if you can elaborate, that would be great.

For example, the link that you provided for the codeproject web service provides an asmx file in which the methods all reside in a single class. What I want is the ability to support mehtods from multiple cs files and choose multiple methods from classes within those cs files. Hopefully this makes sense.

Use Ctrl+Left/Right to switch messages, Ctrl+Up/Down to switch threads, Ctrl+Shift+Left/Right to switch pages.
