In a C# project in VS 2005, when I add a reference to a DLL in the Solution Explorer (using the Browse Tab in the Add Reference dialog) I have to specifiy the full path. That means that if the DLL is a Debug DLL bin\Debug\ appears in the path. So how do I reference the Release DLL for the Release configuration?
Thanks in advance

You don't set a reference to the .DLL, you set it to the project that builds that .DLL, so long as the project is part of the same solution.
|
|
|
|
|
I'm afraid the project isn't part of the solution.

Then you have to add the reference to the Release version manually. There is no way to automatically switch between the two.

Hi ,
I'm having some trouble. My winform app is running SQL Queries , and I would like some sort of a progressbar to be displayed while the query is running (just a progress bar that constantly moves back & forth - I'm using the Circular Progress bar - http://www.codeproject.com/vb/net/sql2005circularprogress.asp[^]
Anyhow - It seems that I need to create a new thread to run the progress bar - If anyone would be so kind and explain me the basics on how to implement this - I would really appreciate it.
Thanks again.

The progress bar is UI. I would imagine you need a new thread to run the query. System.Threading.ThreadPool.QueueUserWorkItem and IsInvokeRequired will get you on the right path.

Thanks. I'd appreciate more information on how to use the IsInvokeRequired exactly ? Sorry but I'm not so familier with threading.
Plus - how do I prevent my app from continuing while waiting for the Query running thread to finish ?
|
|

|

I will have to recommend looking through WinForms threading articles for that answer as it begins to be a deep topic. The Methods I gave you (and maybe it is InvokeRequired instead) should allow you to find the exact articles that will suit your needs.

Hello. I'm attaching a delegate which throws an exception to the BackgroundWorker.DoWork event, but the exception isn't caught by the worker and passed to RunWorkerCompleted event. Apparently it has something to do with asynchronous calling of delegate, since if I make the equivalent named function and attach that to DoWork, the exception is caught as expected.
(My goal is to make a function "RunInBackgroundWithProgressDialog" so that I can launch long functions like:
<br />
RunInBackgroundWithProgressDialog(delegate(){<br />
}); )
Offending code:
using System;
using System.Collections.Generic;
using System.Text;
using System.ComponentModel;
namespace ConsoleApplication1
{
class Program
{
static void Main(string[] args)
{
BackgroundWorker w = new BackgroundWorker();
w.DoWork += delegate(object o, DoWorkEventArgs e)
{
Console.WriteLine("sleeping 1000");
System.Threading.Thread.Sleep(1000);
throw new Exception("thrown");
};
w.RunWorkerCompleted += delegate(object o, RunWorkerCompletedEventArgs e)
{
if (e.Error != null)
{
Console.WriteLine("should be handled here, but isn't");
}
};
w.RunWorkerAsync();
Console.Read();
}
}
}

// do stuff that takes a long time here.
});)
Looking at your code, I think the problem is in the code you aren't showing. The code in BackgroundWorker that calls DoWork needs to call it in a try/catch block and create event args with the exception if an exception is thrown from DoWork.

Blurred on screen usually results in nice print on paper. The blur is most likely from anti-aliasing.

Thanks for your reply but what should i do when i preview on screen the font looks nice and sharp and no problem but as soon as i print then that's where the font messed up. Can you tell me where can i change the fonts.

There is a lot of code there. Have you examined the rtf files themselves and tried to print them from word?

My applicaiton is independent. I don't want to depend on MS word. I have even set to
Graphic.SmoothingMode = SmoothingMode.HighQuality;
Graphics.InterpolationMode== InterpolationMode.HighQualityBicubic;
but no success. I looked in some article tooo but doesn't solve my problem when am printing RTF format text.
Thanks for replying

Actually the point was verification of your code. Does word open the rtf file fine? If yes then examine your rendering code, if no examine your rtf creating code.

Hello,
The code below I have:-
static string filename;
static XmlDocument xmlDoc;
and open the XML file in the Form Load.
If I remove the :- if (testDialog.ShowDialog() == DialogResult.OK)
Line the XML addnode code works OK. With the ShowDialog() line in the XML node add code does not work. Why?
Also is there something I can check (return code?) to make sure each part of the add node lines of code has worked?
void Button1Click(object sender, EventArgs e)
{
NewForm testDialog = new NewForm();
if (testDialog.ShowDialog() == DialogResult.OK)
{
MessageBox.Show("Here");
XmlNode root = xmlDoc.DocumentElement;
XmlElement childNode = xmlDoc.CreateElement("ABCD");
XmlElement childNode2 =xmlDoc.CreateElement("Name");
XmlText textNode = xmlDoc.CreateTextNode("ABCD");
root.AppendChild(childNode);
childNode.AppendChild(childNode2);
childNode2.SetAttribute("Name", "Name");
childNode2.AppendChild(textNode);
xmlDoc.Save(filename);
MessageBox.Show("Here2");
}
testDialog.Dispose();
}
Thanks is Advance,
Rapier

Does your NewForm return a DialogResult anywhere in your code? Supposing that the NewForm form has been created by you.

Hello everyone,
I have a string which contains all sort of charateres. How can I remove the unwanted charaters and make sure what I am left with is Numerical and Alphabet charaters?
Thank you very much and have a great day.

Let's say i want to write code using my own syntax for some reason unknown to mankind, and then generate C# code from this mysterious sourcecode.
Do you guys know if there are there any already existing programs wich can translate an user defined syntax to C#?

They are called language parsers. You may find it better to translate it to IL rather than C#.

Hm okay, are there any specific parser that is easy to start with? preferrably one that starts with C# settings so i can change specific parts only

Triangle, or Mini-Triangle - a training language produced by the University of Glasgow? There is a book about it. (This is not an easy subject and will require a lot of work)
There is also a book on languages parsers with the CLR (which is why I suggested parsing the code and spitting out IL) which shows you how to create a parser and generate assemblies.

I'm trying to create a System.Drawing.Image from a user supplied URL. My code is as follows.. I keep getting a "(407) Proxy Authentication Required" Error.

byte[] imageByteArray = imgClient.DownloadData(imgURL);
MemoryStream ms = new MemoryStream(imageByteArray);
