Wy not read the answers you got when you posted the question only 16 hours earlier, instead of posting it again?

While I am grateful for any response...I read them and they donn't work.

Well, if they don't work, say so. If you give no response at all to the ones that answer your question, but just post it again, it looks that you are completely ignoring the answers that you already got, giving no regard at all to the people trying to help you. Is that really the way you like to appear?
As you see, you will get the same answers all over again.
And did you really try the way that I suggested?

Hello everybody here!!!.
i would like to know how can i add new command to the run process of the windows os for example .
press the following
--------------------
start ---> run --->and type ---->cmd or regedit
it will open the MsDos or Registry of the Windows OS respectively but i want to add new command like this of my own is it some string key or entry in the registry that manages this and by the way yahoo messenger do the same when you expose one friend's email from yahoo online member directory, you will see the online icon and you press that icon with this simple html script:
<br />
<a href="ymsgr:sendim?the_Friend_nickname">the online icon</a><br />
and it is it it opens for you private window for chatting with that friend.
I want to add command of my own like this any body has any solutions for this please refer to me with an idea or even an article on this.
As i guess ! it is all related to enter new key value data in the registry in specific part with the extension of your program , but where i don't know any body can help me in this please ..
Thanks From my heart

Simple commands like cmd or regedit can be called because they are programs that can be found with the PATH environment variable. Start->Run also finds programs using the registry key "SOFTWARE\Microsoft\Windows\CurrentVersion\App Paths" if the program cannot be found using the PATH variable.
Registering new protocol like "ymsgr" is something different, but also quite easy: see http://msdn.microsoft.com/workshop/networking/pluggable/overview/appendix_a.asp[^]

You posted the exact same question in this exact forum less than 20 hours ago.
Why don't you follow up on the answers you get instead of spamming the forum with the same question again?

Hello everybody,
How can i open a webpage in C# that has post data already sent to it(or download the HTML code of that page)
example:
A dictionary that uses POST to send the word to the result page. I need a program that can display the coresponding page for the required word.
Thanks in Advance

Hi Afief,
I'm not sure if I'm understanding you correctly, and whether you actually want to open a browser window to display the page, or to programmatically receive the content of a page as a result of a POST.
If it's the latter try something similar to below (untested) which POSTS a string to a web-page and captures the response also as a string:
static string Post(string url, string wordToPost)
{
// convert the word to post to a byte array
byte[] postData = new System.Text.ASCIIEncoding().GetBytes(wordToPost);
// create a web request
System.Net.WebRequest request = System.Net.WebRequest.Create(url);
// verb is POST
request.Method = "POST";
// add the post data to this request
System.IO.Stream postStream = request.GetRequestStream();
postStream.Write(postData, 0, postData.Length);
postStream.Close();
// send the request and collect the response
System.Net.WebResponse response = request.GetResponse();
// now read from the response stream the output
System.IO.StreamReader reader = new System.IO.StreamReader(response.GetResponseStream());
string result = reader.ReadToEnd();
// tidy up
reader.Close();
response.Close();
// and return the content
return result;
}

Hi!
I am developing a windows application which crops an image by drawing a rectangle over the image using mouse (RubberBand Effect)
Can somebody tell me how do I keep the Aspect Ratio when drawing Rectangle over the image using mouse.
i.e. when drawing selection in Adobe PhotoShop with Aspect Ratio
Anxiously waiting for reply.
|
|
|
|
|
int startx,starty;
int x,y;
double ratio=1; // change this for photos or screen wallpapers(ie. 1.3333)
if(x<startx)
startx=x;
if(y<starty)
starty=y;
int length;
if((x-startx)="">(y-starty))
length=y-starty;
else
length=x-startx;
drawrect(startx,starty,startx+length,starty+length);
should work. you only have to write drawrect(int x, int y, int endx,int endy) procedure.

Thank you for replying, but, I did not understand your code, you have declared the variable "ratio" but you have not used it any where. I will be pleased if you read my code and modify it for Aspect Ratio functionality.

Hi there,
I'm trying to check whether a string contains numbers. Here is my code, which obviously doesn't work. How do I check properly for matches? In this example, I've been using the Match.Length property. As well I tried with the Match.Success property but it doesn't seem to work either.
string sEx = "[0-9]*";
string sText = "hi t 2 o all of you!";
Match m = Regex.Match(sText, sEx);
if (m.Length > 0)
Console.WriteLine("worked");
else
Console.WriteLine("didn't work");
Any help is greatly appreceated!

The regex will "[0-9]*" will search for zero or more digits, so it will find zero digits in any string. (in your example, it will find the zero-length string in front of "hi")
Use 'Regex.IsMatch(sText, "[0-9]")', which will return true as soon as one digit is found.

You create an event handler for the paint event of the element where you want them drawn. Invalidate the element to cause it to be redrawn.

hi,
i have a problem.i'm usin Component one TrueDbGrid. Also i have dragged a dateTimePicker on it..as per the samples which Component One had, i wrote the code for a particular column to be of type "dateTimpicker"..ther code comes in RowColChange event of the trueDbGrid...
private void c1TrueDBGrid1_RowColChange(object sender, C1.Win.C1TrueDBGrid.RowColChangeEventArgs e)
{
// position the datetime picker on the "BirthDate" column only
C1.Win.C1TrueDBGrid.C1DataColumn col = this.c1TrueDBGrid1.Splits[0].DisplayColumns[this.c1TrueDBGrid1.Col].DataColumn;
if( col.DataField == "BirthDate" )
{
// get the area of the cell
Rectangle r = this.c1TrueDBGrid1.Splits[0].GetCellBounds(this.c1TrueDBGrid1.Row, this.c1TrueDBGrid1.Col);
// change to screen coordiantes
r = this.c1TrueDBGrid1.RectangleToScreen(r);
// map the screen coordinates to the forms client coordinates
this.dateTimePicker1.Location = this.RectangleToClient(r).Location;
// size it to fit inside the cell
this.dateTimePicker1.Size = r.Size;
// default the dateTimePicker to the date in the cell
this._bIgnoreChange = true;
this.dateTimePicker1.Text = col.CellText(this.c1TrueDBGrid1.Row);
this._bIgnoreChange = false;
// display it
this.dateTimePicker1.Visible = true;
}
else
this.dateTimePicker1.Visible = false;
}
so here if the col == "BirthDate", then tat field where i've clicked, becomes of dateTimPicker...but my problem is the dateTimepicker is visible but it doesn't get the correct size and location...y this happens i dont understand...
plz..help me..m stuck...
