I use WinForms Microsoft ReportViewer in local mode.
I want to use C# syntax in report expressions.
How to use C# instead of VB.NET syntax ?
I'm thinking about the following approaches:
1. Create pre-processor which converts expressions in RDL file from C# to
VB. NET
2. Replace all expressions with a method which takes C# expression as string
parameter, evaluates it returns result.
Any idea how to implement this ?
Where to find any samples of C# expression evaluator or C# to VB .NET expression converter ?

Hello,
The business class of my application caters to both, a web service and the windows UI application. One of the business class, loads an assembly dynamically and invokes a particular method on the type in that assembly. This works fine when the call is originated from Windows UI app. but when I call the same method of BC from webService I get an exception of "Method not found" when the method is invoked after loading the assembly dynamically.
Not understanding the reasonong, I tried various things. One of them was using remoting. I created a marshallar class (a class inheriting from MarshalByRef Class) and wrote an Invoke method in that. In the constructor of Marshallar I created the handler by creating instance of type from assembly which I wanted to load dynamically. In the invoke method I wrote type.InvokeMember. By loading this marshallar assembly into a new AppDomain, my webService call completed without any exception !!!
but now I have another problem, this particular assembly is used for processing of heavy amount of data and when the method is invoked as a remote method call, it takes too much of time and the performance is getting hampered greatly.
Can anybody tell me why a remote call succeeds and a local call fails in case of web service ?
Thanks in advance.

Hi,

Hi all
I'm doing a C# function retrieving a line of text from a Win32 edit box.
Platform SDK says the folowing: before sending the message, set the first
word of this buffer to the size in TCHARs, of the buffer. For ANSI text, this is the
number of bytes; for Unicode text, this is the number of characters.
How to do that with StringBuilder? I tried to set
StringBuilder ItemText = new StringBuilder(256);
//ItemText[0] = 250; //I'm not usre of that!!!!
IntPtr lenOfString =
Win32Api.SendMessage(
_hWnd,
EM_GETLINE,
IntPtr.Zero,
ItemText
);
but it doesn't work even if for example I set ItemTex[0] = 'a'
with a caracter.
How to handle dimension I want into first character of the stringBuilder
so that WinApi read it correctly?
Regards

C# is Unicode. I believe you'll find it's the length of the string * 2.

The user enetered the information in Page1.apsx page and navigated to Page2.aspx. Now the user is coming back to Page1.aspx. How can I prepopulate previously entered data in Page1.aspx. (Where Can I save the data when the first time entered to prepopulate while coming back?)
Please Note: I should not use Sessions.
Thanks in Advance,

Is it possible to do in 1.1?

The easiest way to do this, is to make page1 and page2 controls that exist on the one page. You can then change which page is visible at any time, and both pages will still have viewstate, so when you go back, page1 will not have lost it's values.
The other way to do it, is to pass an Id on the Url and use that to get your values from your database, if they are something that has been saved there.

there is a dll. code below
--------------------------
namespace CommonFunctionLibrary
{
public class ClsMain
{
public string setValue(string a,ref string b)
{
b = a;
return a;
}
}
}
-------------------------------------------------------
and there is a Host
--------------------------------------------------------------------
string filepath = @"E:\VS2005_work\CommonFunctionLibrary\CommonFunctionLibrary\bin\Debug\CommonFunctionLibrary.dll";
string s = string.Empty;
string p = string.Empty;
Assembly myDllAssembly = Assembly.LoadFrom(filepath);
Type dllType = myDllAssembly.GetType("CommonFunctionLibrary.ClsMain");
MethodInfo dllMethod = dllType.GetMethod("setValue");
if (dllMethod != null)
{
Object dllObj = Activator.CreateInstance(dllType);
s=(string)dllMethod.Invoke(dllObj, new object[] {"goldli",p });
MessageBox.Show(s+"\r\n"+p);
}
myDllAssembly = null;
------------------------------------------------------------------------------
question:
1、the Invoke method no need to use "ref" ,why?
2、the "p" parameter has no return value,why?
|

Hi..
I'm not sure but:
1. the ref is only valid in method calls and causes a parameter to be passed as pointer so it can be modified.
2. p does not contain the new value because this doesn't work either:
<br />
string s1, s2;<br />
s1 = "Blah";<br />
s2 = s1;<br />
s2 = "foo";<br />
Console.WriteLine(string.Format("{0} {1}",s1,s2));<br />
the output will be "Blah foo" because a new string is a new object.
the way i understand it, you should do the following:
<br />
string filepath = @"E:\VS2005_work\CommonFunctionLibrary\CommonFunctionLibrary\bin\Debug\CommonFunctionLibrary.dll";<br />
string s = string.Empty;<br />
string p = string.Empty;<br />
Assembly myDllAssembly = Assembly.LoadFrom(filepath);<br />
Type dllType = myDllAssembly.GetType("CommonFunctionLibrary.ClsMain");<br />
MethodInfo dllMethod = dllType.GetMethod("setValue");<br />
if (dllMethod != null)<br />
{<br />
Object dllObj = Activator.CreateInstance(dllType);<br />
object[] parameter = new object[] {"goldli",p };<br />
s=(string)dllMethod.Invoke(dllObj, parameter);<br />
p = parameter[1].ToString();<br />
MessageBox.Show(s+"\r\n"+p);<br />
}<br />
myDllAssembly = null;<br />

Hey Guys,
I'm developing a C# application this time i've decided to include crash reporting. I searched CP and found this
See this
Its in C++ though. I know i can call the unmanaged DLL from C# but Id prefer one in managed code. Is there a crash reporting library in managed code? I couldn't find any!

Hello everyone,
I have a ListView which I am sending some information HH:MM:SS into it everytime the user click a button. I wish to have a column which increments evertime the button is clicked and an item is added to the ListView.
Is there any easy way I can get this one done?
Thank you so much for your help and have a great day.

If you have a new column, it's going to appear for every row. You can just add a column, and have the button click find the values there and increment them.

Hi,
im developing an application in c# .net 1.1 using VS2k3.
In that app I'm trying to open a System.Windows.Forms.FolderBrowserDialog.
Here is the code:
<br />
System.Windows.Forms.FolderBrowserDialog folderBrowserDialog = new FolderBrowserDialog();<br />
folderBrowserDialog.SelectedPath = System.Environment.CurrentDirectory;<br />
folderBrowserDialog.ShowNewFolderButton = true;<br />
DialogResult res = folderBrowserDialog.ShowDialog(this.maindlg);<br />
if(res == DialogResult.OK)<br />
{<br />
...
}<br />
It works just great, except that when I click on the "Create new directory" button, a new directory will be created, but not shown in the dialog. When I close the dialog and start it again, then the new created dir will be shown. So there is a need to refresh the directory list in the dialog when the user hits the "create new dir" button.
Does anyone know how I can perform this?
thx and best regards

It works in my VS2003. Try to use only .ShowDialog();
|

Hi,
thanks for your reply.
I checked it out with .ShowDialog():
<br />
System.Windows.Forms.FolderBrowserDialog folderBrowserDialog = new FolderBrowserDialog();<br />
folderBrowserDialog.SelectedPath = System.Environment.CurrentDirectory;<br />
folderBrowserDialog.ShowNewFolderButton = true;<br />
DialogResult res = folderBrowserDialog.ShowDialog();<br />
if(res == DialogResult.OK)<br />
{<br />
...
}<br />
Unfortunatelly there is still the same problem.
Please note that I'm running on WindowsXP and that the code is part of an internal class which is not inherited from UserControl or Form.

Hi,
I just found out that I've the same problem with the System.Windows.Forms.SaveFileDialog.

Hi again,
I found out that it works, when I start the application outside of VS2k3.
It definitly does not work, when I start it inside of VS2k3 by hitting the "play" button.
Maybe there is something wrong with my VS settings.
Anyway thx

Hello everyone,
I have some data "Hour, Minute, second" which I would like to display in the format of "HH:MM:SS". As the digits can be a single and double I would like to put a "0" for a single digit.
Can anyone tell me how I can format this?
Thank you very much and have a great day.
