Hi,
I am loading a dll say XYZ.dll dynamically from console application by using activator.createinstance() method. This XYZ.dll is having reference to a data access layer ABC.dll which has reference to the 3 MS-DAAB dlls of enterprise library:
1. Microsoft.Practices.EnterpriseLibrary.Data.Configuration.DatabaseSettings
2. Microsoft.Practices.EnterpriseLibrary.Data
3. Microsoft.Practices.ObjectBuilder
I have placed these 3 dlls and ABC.dll in the folder with the exe of console application. However XYZ.dll is not placed there as it will be loaded at runtime specifying a certain path. Now when I try using code which uses the MS DAAB dlls then I am getting an error:
Unable to cast object of type 'Microsoft.Practices.EnterpriseLibrary.Data.Configuration.DatabaseSettings' to type 'Microsoft.Practices.EnterpriseLibrary.Data.Configuration.DatabaseSettings'
(I do not get this error when I am not dynalically loading the dll)
Note: I have specified the dataConfiguration section in App.config of Console Application.
Any help is appreciated.

Hello..
I want to use the DataGridView only as View, that's why, I don't want to allow user to select any cell.
If user select a cell, it will be marked as "dark blue cell". How to avoid this ?
Are there any properties to disable any selection from user ?
Thx...

you can set the DefaultCellStyle of a DataGridView, this will allow you to give the appearance of the Cell NOT being selected. like this ...
<br />
DataGridViewCellStyle style = new DataGridViewCellStyle();<br />
style.SelectionBackColor = Color.White;<br />
style.SelectionForeColor = Color.Black;<br />
dataGridView1.DefaultCellStyle = style;<br />
BUT, the easiest would be to use the CellStateChanged event, like this ...
<br />
private void dataGridView1_CellStateChanged(object sender, DataGridViewCellStateChangedEventArgs e)<br />
{<br />
if (e.Cell.Selected)<br />
{<br />
e.Cell.Selected = false;<br />
}<br />
}<br />
<br />
hope it helps

I need to write a manager program connect to a remote server to display the status of the server. I have a login form, when i connect successful it will show the main form. In this form I have a lot of buttons (on the left panel), each button when we click will open a new form (on the right panel).
I want to declare and initialize all the variable at the beginning of the program, in Program.cs file and using the varialbes and methods in other forms. See the code Snippet below.
My question is that, when I initialize an instance of AManager in region checkManagerAPI() like above:
_manager = new AManager(host, port, loginame, loginpwd);
When I change to another form, why I can't use the _manager again? How to make it become global access?
using System;
using System.Collections.Generic;
using System.Windows.Forms;
namespace MainForm
{
static class Program
{
const string host = "10.0.0.2";
const int port = 5000;
const string loginame = "name";
const string loginpwd = "pwd";
.....
public static AManager manager;
///
/// The main entry point for the application.
///
[STAThread]
static void Main()
{
Application.EnableVisualStyles();
Application.SetCompatibleTextRenderingDefault(false);
checkManagerAPI();
Application.Run(new FrmMain());
}
// checkManagerAPI() region is here:
#region checkManagerAPI()
checkManagerAPI();
{
manager = new AsteriskManager(host, port, loginame, loginpwd);
//a lot of code....
}
#end region
}
}

public static is global. Perhaps you would be better to use delegates, or create a public static class to hold just the data you ant to share ?

hy everyone!
what happens in cases like this:
string myinput = "12345678910";
myinput = myinput.toString({0:10});
Does this throw an exception or does it cut off all charecters > 10 ??
Because I want the string to be insert no matter if it is too long or not. If it is too long then this should be handled by a warning but the string should be insert without cutting off anything.
So I wonder if this function tries to format it to length 10 but accepts strings which are longer as well, or if it doesn't. Because if it doesn't then i have to take care about this myself by checking, if the string is too long.
Thanks.
Stephan.

Why write such a long post instead of just trying it to see ?

stephan_007,
What language is this in?, because it doesn't compile in C#.
Regards,
Gareth.

it's c# but i didn't copy it from my source, i just typed it into here. maybe i misstyped it.
the reason why i posted it here is, maybe someone already did anything similar and could help me to keep it simple
because it looks like i usually solve problems in a too difficult way which could be solved by default functions. that's why.
i know i could try the two statements above in my own code, but as i already said, maybe someone knows a different way to format the string without raising an error 
|
|
|
|
|
ups, i misstyped the second line!
it should be
myinput = String.Format("{0,10}", myinput}
and i already found out, it ignores the formating, if the string is longer than defined in the formatsring. so i have to check it myself, by splitting off the relevant position in the format string to compare it to.

I believe it will throw an exception..even sql server throws an exception that warns that string data is bieng truncated. your best solution would be to either limit what the user can type in, or check its length before you try to insert it, and either truncate it yourself, or tell the user that the input is invalid(best solution so the user doesnt get bad data in the db or where ever you're putting it)
|
|
|
|

the user wants this behaviour:
if the string is smaller or equal the length defined in the format string, then just insert it, if it is longer than the length defined, then the programm should throw a worning, but insert the data anyway.
i have to insert it into a stream. so if it is too long, then all other info is moved x characters to the right (x is the difference to the defined and the real length).
well, because it just ignores the length if it is too long, i have to write a check myself to know, if i have to throw a warning or if the length is ok.

you should probably try to explain to the user that just inserting the data even if its too long is a bad idea. you could just use the string.Length to find out how long it is, and use Remove to cut off any unwanted characters

Dear all,
I am building a c# application. I wanted to add to it the capability that i dictate a URL and then write it in a text box, so i searched and i found that i should use class "DictationGrammar". However i couldnot find an intact example or set of steps to follow to build the required utility. I would appreciate it if anyone could help...

Hi,
on My form I have about 150 controls at the same time, and most of them use docking.
some of them are childs in childs in childs of controls.
Whenever I resize my form it takes a long time for it to rearrange and ready to workwith.
I manged to speed up things in the proccess of adding all the controls by using ResumeLayout and SuspandLayout. But what should I do in the proccess of resizing?
How can I find out when the resizing event startend and when the resizing is finished?
tnx leeoz

Resize event doesn't quite work like that, it gets fired when the forms size has changed. So when you resize your form with your mouse, every time you see a visible change in the size of your form, then event has been fired.
Sadly you can't get the mouseDown mouseUp events for clicking on the border. The only way i know to get that information is to override WndProc and look at the messages, one of them is sent when you mouse down on the caption bar/border and other are sent when the mouse moves or the button is released.
But, i tried using SuspendLayout and ResumeLayout with docked controls, and i think after ResumeLayout the controls just stayed where they were. So you should check that.
Good news is though, if you also override the OnPaint event you can stop any drawing yourself. So if you use WndProc to work out when the form is being resized then you can set a bool to false or something, and have an if statement around base.OnPaint(e); in your OnPaint override. Of course even without drawing it will still try to reposition all of the controls every time the resize event is fired, so it may still end up going slow.
Well, good luck.

Hello. I have to open an outlook item using the hyperlink like <Outlook:Sent Items>. This technique is described here http://support.microsoft.com/kb/225007. As i understand, such links are to work in the explorer address bar as well. But instead, IE just can't display the page. Could anybody explain how it should work?
Than's in advance.

|

Well i just tried it and it does work, but IE doesn't show the page. Outlook just opens on the Sent Items folder. And just in case, you don't actually type the <> signs.

Very strange, because it does not work with my configuration. Could you please tell me what Outlook and IE versions you use? I have IE6 and Outlook2007 installed. Thank you.
