Thanks, will keep in mind, currently it's only getting the client details, Company name etc..

I know if you use the installer helper class, you can reference the installation path with

path = Context.Parameters["assemblypath"]

Problem is that it returns the whole installation path including the executable. eg

C:\Program Files\Test\Test1.exe

what I want is just the

C:\Program Files\Test\

Any Ideas???

Thanx

Well that's simple: Just use Path.GetDirectoryName() to get only the directory.

I want to print many pages one times,but the print result was wrong!the print Height was small than my degsin heigth!
my report's properties set like these:

MarinTop Blush | :O

.5cm
MarinLeft Blush | :O

.2cm

PageWidth:13.9cm
Body Property:

Width:12.9cm
Table Property:
PageBreakAtStart:false

I see some document write like this:"If the PageHeight is less than the PageWidth, then it is landscape, otherwise it is portrait.While you can programmatically change these via the SetProperties method on the web service, they will be overwritten if the report is republished. "

The Print Result is wrong ,the Print Result width is right,but the
height is wrong ,is small than 13.9cm,only 7cm ,the Font was small too.

Take a look at the NSIS project[^]. Its an easy-to-learn and in my opinion very useful open source system for creation of Windows installers. Among many others the web site provides a code example for Installing the Microsoft .NET Framework[^].

Resetting Screen Scroll Position on a Winform

I have a main form that is set to auto scroll so that when lower screen resoloutions are used, scroll bars are provided. The controls are not getting set back to position 0,0 but are displaying where ever the last scroll bar displayed the previouse control. Any way to get the controls to reset to display back at 0,0 and the bottom scroll bar to reset back to the left and the right one back to the top?

Initializing dictionary with a struct? help pls

Hi guys what is wrong with this line? lookupObject is a struct. I just want to initialize the dictionary with the struct as value.

public static Dictionary<string, lookupojbect=""> dicTextLookup = new Dictionary<string, lookupojbect="">();

this is the error: "Error 1 Inconsistent accessibility: field type 'System.Collections.Generic.Dictionary<string,lookupojbect>' is less accessible than field 'dicTextLookup' C:\IL\TranslationController.cs 44"

Thanks

Could you repost that snippet, but check the "Ignore HTML tags in this message" checkbox when posting? We can't see your full code otherwise.

Is dicTextLookup non-public? Are you exposing the field as public? This error typically occurs if you're trying to expose some private/protected/internal thing as public. For instance

private class MyFoo {}

public class MyBar()
{
    public MyFoo instance; // Error: inconsistent visibility: MyFoo is private, yet we're trying to expose the field as public
}

thanks dude!

You could use a regular expression, something like RegEx("[0-9]")

Don't implement it that way. Exceptions should be used only for exceptional circumstances, not part of normal code flow.

Rather than doing that, either us a MaskedTextBox (new in .NET 2.0) or use a regular expression to validate the input.

Include the Visual Basic library and use the IsNumeric method.

Here is an easy way that doesn't rely on exceptions, regular expressions, or legacy VB libraries:

double numericValue;
bool isNumeric = double.TryParse(myTextBox.Text, out numericValue);
