Which would be considered better practice? Although the first version is smaller the second one uses string builder and breaks it up so that it is easier to distinguish what is being added to the line and avoids hard coding in the actual program. So which would you normally do? Both of these create the same URL in the end.
Stringing it all together like this?
<br />
string strRedirect = "~/Maint/surcharge.aspx?" +<br />
"StartDate=" + cpStartDate.SelectedDate.ToShortDateString() +<br />
"&EndDate=" + cpEndDate.SelectedDate.ToShortDateString() +<br />
"&Market=" + ddlMarkets.SelectedIndex +<br />
"&GroupName=" + cbCustomer.Checked.ToString() +<br />
"&GroupCode=" + cbGroupCode.Checked.ToString() +<br />
"&Abbreviation=" + cbAbbreviation.Checked.ToString();<br />
Or using a string builder to create the URL like this:
<br />
private const string URL_SURCHARGE = "~/Maint/homepage.aspx";<br />
private const string STR_ASP_DELIMITER = "&";<br />
private const string STR_ASP_PARMS = "?";<br />
private const string STR_ASP_EQUALS = "=";<br />
<br />
private const string DF_START_DATE = "StartDate";<br />
private const string DF_END_DATE = "EndDate";<br />
private const string DF_GROUP_CODE = "GroupCode";<br />
private const string DF_ABBREVIATION = "Abbreviation";<br />
private const string DF_GROUP_NAME = "GroupName";<br />
private const string DF_MARKET_TYPE = "Market";<br />
<br />
StringBuilder sbRedirect = new StringBuilder( URL_SURCHARGE );<br />
<br />
sbRedirect.Append( STR_ASP_PARMS );<br />
<br />
sbRedirect.Append( DF_START_DATE );<br />
sbRedirect.Append( STR_ASP_EQUALS );<br />
sbRedirect.Append( cpStartDate.SelectedDate.ToShortDateString() );<br />
sbRedirect.Append( STR_ASP_DELIMITER );<br />
<br />
sbRedirect.Append( DF_END_DATE );<br />
sbRedirect.Append( STR_ASP_EQUALS );<br />
sbRedirect.Append( cpEndDate.SelectedDate.ToShortDateString() );<br />
sbRedirect.Append( STR_ASP_DELIMITER );<br />
<br />
sbRedirect.Append( DF_MARKET_TYPE );<br />
sbRedirect.Append( STR_ASP_EQUALS );<br />
sbRedirect.Append( ddlMarkets.SelectedIndex );<br />
sbRedirect.Append( STR_ASP_DELIMITER );<br />
<br />
sbRedirect.Append( DF_GROUP_NAME );<br />
sbRedirect.Append( STR_ASP_EQUALS );<br />
sbRedirect.Append( cbCustomer.Checked.ToString() );<br />
sbRedirect.Append( STR_ASP_DELIMITER );<br />
<br />
sbRedirect.Append( DF_GROUP_CODE );<br />
sbRedirect.Append( STR_ASP_EQUALS );<br />
sbRedirect.Append( cbGroupCode.Checked.ToString() );<br />
sbRedirect.Append( STR_ASP_DELIMITER );<br />
<br />
sbRedirect.Append( DF_GROUP_CODE );<br />
sbRedirect.Append( STR_ASP_EQUALS );<br />
sbRedirect.Append( cbAbbreviation.Checked.ToString() );<br />

The best of both worlds:
sbRedirect.AppendFormat("~/Maint/surcharge.aspx?StartDate={0}&EndDate=(1)&Market={2}&GroupName={3}&GroupCode={4}&Abbreviation={5}",
cpStartDate.SelectedDate.ToShortDateString(), cpEndDate.SelectedDate.ToShortDateString(), ddlMarkets.SelectedIndex, cbCustomer.Checked.ToString(), cbGroupCode.Checked.ToString(), cbAbbreviation.Checked.ToString());

i want to send voice over network in C# or VB.net.
but in .Net framework there is no facility for
handeling Sound Card except DirectX.DirectSound .
i'v been use it but there is a problem.
in DirectX when you change the control from the form
of your program the sound process will be stop.
this is becouse that i must use the
public void SetCooperativeLevel(
Control owner,
CooperativeLevel level
);
function.
I try API in .net but it has itself problems.
do you know any way that save me from this hell.
i want to capture the sound send it on the network and
then play it at the otherside.

You're not too bright, are you ? DirectX is free to download from the Microsoft site. It's far to big to fit in your inbox.

how to make an area in the form have an opacity less than the hole form?
and how to make the area of desktop behind this area accessable by
the user -(as it looks like a transparent area)- from within this area ?

I doubt that you can, unless you make the whole form have the low opacity, and then draw the rest of the form on top. Windows needs to draw the form underneath and it can't do that if it's not at a low enough level.

This has nothing to do with GDI+. I suspect you want the area to not be part of your window at all, which is quite possible. Look into irregular shaped windows.

Hi
I have made a dll given it a strong name and added it to the GAC.
Why can't I now add a reference in another solution to that dll via the add reference/ .Net tab?

Hi,
How can I use the FileSystemWatcher to watch the whole C drive file operation ? The class seem can only watch just one directory(the first level).
Thanks
|

You COULD recursively create FSWatchers for all directories, but I wouldn't do that.
I think that C# might not be the best language to do something as OS-close as this.
You probably will want to hook all calls to the HD, which suggests using C/C++ instead.
Actually, if you want this in C#, look for a way to get around having to watch the whole partition and only monitor certain directories.
I am not sure if there is a "file change notification"-Win-Message, but if there is, you might be able to watch for those instead, then reread the affected directory.
Cheers
Sid

There is the IncludeSubdirectories property that forces it to watch all levels below the one specified. I guess if you point it at the root of the drive you want to watch, it would work.

Hi,
I had made one logic by which i can able to delete the user selected colors.logic is that get the minimum and maximum value of R,G,B of each pixels and then remove that colors from whole pixels.Now here it's working fine but main problem of this logic is that as it's taking minimum and maximum value of R,G,B if user select the color in which there is one white color pixel of my logic taken white color value in min. value and so it removes all the colors from the image instead of selected color.
so i need to make some more improvement of this logic?can any one help out or guide me in changing this logic ?
i think here one idea can solve this problem.
thanks

Yepp, it probably can:
You need to split this up into different "filters".
The first thing you will need is a "Replace selected color" filter, which should replace one color with another. You could determine the "new" color using your logic, just like you calculated the "new" values for your pixels, just that you dont do this to every pixel in the picture, but only those that have exactly the same color values.
The second filter extends the first: "Replace colors", which should replace all colors in a certain range (e.g. "R245 to R255") with a given color (or simply "swap" R for B or something similar). In that case, you select one pixel, give a certain "range" (eg. +-10) and then select a "replace method" (so you can provide different methods).
Third would be a "grayscale replace" in which you split RGB channels and treat each channel seperately.
The fourth and last filter I can imagine is a RGB Filter. That means, my simply choosing a color (Red, Green or Blue) to remove, the image would be treated as a whole. You could (again) simply "split" the image and then only recombine G and B, with Red set to a "standard value" (e.g. 0) which then would yield a "red-free" version of your image.
Cheers
Sid

Hi,
I think this will not works becoz here as this is four layer filteration the performance gets effected tremandusly,but if you give some less layer filter but effective than it's good.

G'day folks,
well i am attempting to get an understanding on how to create the menuitems in a context menu on the fly. So far I have managed to actually achieve the menu items being created for the context menu. However, I have stumbled across one problem. Which is that how does one go about enhancing the event handler for the context menu to invoke individual actions for each of the menu items.
I have included a snippet of my code. In this sample example, I created a button, which essentially adds 4 menu items based on strArray to the context menu. Any recommendations on how to improve the context menu event handler so that when I click on menu item "A" in the context menu, the message box pops up.
Any recommendations will be appreciated.
thanks in advance.
string[] strArray = {"A", "B","C","D"}; //declared as global
private void contextMenu1_Popup(object sender, System.EventArgs e)
{
try
{
MenuItem miClicked = (MenuItem)sender;
string item = miClicked.Index.ToString();
switch(item)
{
case "A":
MessageBox.Show("A");
break;
case "B":
MessageBox.Show("B");
break;
case "C":
MessageBox.Show("C");
break;
case "D":
MessageBox.Show("D");
break;
}
}
catch
{}
}
//creating menuitems for context menu when the Push Button is pressed.
protected void button1_Click(object sender, EventArgs e)
{
for(int i=0;i

hehe, I know what you mean.
I used the following approach:
First, I extended the controls (in my case, buttons):
public class nodeButton : Button
{
private int index
// getter and setter go HERE
}
My "on-the-fly" generated controls are first stored into a control[]. At the same time the control is added to the array, I set the index-int to the controls index in the array.
I then have ONE event handler
nodeButton_Click
which is added to each nodeButton control at the same time the index is set.
Thus, using ((nodeButton)sender).index gives me information on which control has been clicked (and I can change the control accordingly).
so, lets say you created your controls and want to dispose of the control[] - no problem, each control is still referenced by the panel, form or whatever you use, with its unique index still intact, so you can find it again.
Just a few ideas

thanks for your feedback Sid. But I am still a bit confused. I was hoping you could give me another example bit simpler with code so that it can really sink in. Or even a link to a tutorial covers this topic.

I used this technique to load Plugins into a MenuItem and fire those events, with the user being able to freely change the item's menu position without having to re-assign events.
How that worked?
The user copies plugin dlls into the apps directory. each plugin has a GUID of some sort, which is used as the identifier on both the plugin and the item. This way, I can simply load the plugins up and let the user arrange them the way he needs them. I then simply look up the plugin via the identifier and let it do its stuff.
OK, some people will frown now. You are right, and it just occured to me as I read my explanation, that I am so freaking dumb.
This IS a solution to your described problem, but its totally crap for what I did. I was assuming that, as the Item Position changes when you modify MenuItem.Index, the associated handlers would somehow swich items. Bullshit. I never needed those, I just had to assing the plugin.dostuff to the appropiate MenuItem. NAAAAAAAAAAAAAAAAAARGH! 
I guess I need more sleep

Im gonna do something very interesting tomorrow afternoon (I want to see if it works out). I dont want to go into any details, but that MAY be fun.
However, I am too tired. I came home late and tried to chop up a few lines to solve your problem.
That did not work out the way I thought it would. I did not reread your - or my - post, and simply assumed this was what you wanted. I read your startpost and my first reply and understood that I did not post what you or I wanted..
Shame on me. I need to get some sleep now, so try if you can use any of this code and come back tomorrow at the same time, I might have posted something useful by then.
Cheers

G'day Sid,
I think you have gone beyond the call of duty. Actually, you probably wont like to hear this but I came up with a novel solution myself. The night I had replied to your solution which i had found difficult to understand. Well the next morning I took another look at your difficult solution and an idea spawned which helped me overcome my problem. I couldnt believe it was so simple, so it looks like C# is slowly sinking into me .
I skimmed through your second solution and will go through it line by line once I get some sleep tonight. 
Once again a million thanks for helping me out here.  I truly appreciate it.
many thanks
Veeral
