I had set the comboBox.DisplayMember = "Cname" (name of company)
comboBox.Valuemamber="Cid" (id of company)
but still not ok??
Eduard Keilholz wrote: combobox.SelectedValue
I also had tried this, but its giving error "Datatype mismatch in criteria exprssion"
Also when i debug the query, comboBox.SelectedValue gives the index value of selected item, not the Cid feild value from Company table.
any suggestion or link u can fwd me.

this code works fine for me:
this.comboBox1.DataSource = this.dataGridWrapper1.table;
this.comboBox1.ValueMember = "ID";
this.comboBox1.DisplayMember = "DT";
:
:
:
private void comboBox1_SelectedIndexChanged(object sender, EventArgs e) {
string s = this.comboBox1.SelectedValue.ToString();
}
I get the id corresponding to the selected dt
Until you realize this message has nothing to say, its too late to stop reading

thanks a lot.
I had set the sort property of combobox= true,
this is creating trouble.
But, why its creating the error. Any clue?
But still there is another problem,
When the query is giving error, it stops at fill method of DAdapter,
The exception is "Datatype mismatch in criteria expression"
I cheked the DB datatype, both are same in both column.
Do you know the reason.

show the concatenated string
like
"select * from table where cid ='" + comboBox.SelecteValue.ToString() + "'";

So what happens when I visit your site from the UK and my language is set to "en-gb"? I can understand "en-us" but you won't display anything to me.
Also, your database is not normalised. What happens if you want to add a new language in the future? This article might help: Normalising the data model[^]

Since you don't say how it doesn't work we can't actually give you any specific help. HOW does it not work? WHAT does it do that it should not? WHAT doesn't it do that it should?

the idea is when the user are in the default.aspx he or she can from an calendar choose some events which are disposed in the calender and it's information is poped up in a panel where you can se the different language for events.....
So I select a day from the calendar which are underlined and the panel is not show the information...
this code I'h in the masterpage.cs to for the calendar
protected void calEvents_DayRender(object sender, DayRenderEventArgs e)
{
DataSet ds = CacheUtility.GetEvents(Cache);
DataView dvEvents = new DataView(ds.Tables[0]);
string strFilter = String.Format("eventDate >= '{0}' AND eventDate < '{1}'", e.Day.Date.ToString("yyyy-MM-dd"), e.Day.Date.AddDays(1).ToString("yyyy-MM-dd"));
dvEvents.RowFilter = strFilter;
e.Cell.VerticalAlign = VerticalAlign.Top;
if (dvEvents.Count > 0)
{
e.Cell.Controls.Add(new LiteralControl("<p>exhb</p>"));
e.Cell.BorderColor = System.Drawing.Color.Black;
e.Cell.BorderWidth = 1;
e.Cell.BorderStyle = BorderStyle.Solid;
e.Cell.BackColor = System.Drawing.Color.Yellow;
}
}

abstract class is base class.why we declare in abs class.
and we implement in child class. directly we can implement in
child class.what reason?....
|
|
|
|

polymorphism
betonglasermur.FeedDwarf(pur_is, 17);
ProcessStartupInfo.AintNotCreateNoWindow = (false && !true) != (true || false) ? false == true ? true : false : (true != false && false);

Because any class that derives from your abstract class is now forced to implement any abstract methods you may have there.

You could extend that argument to all base classes - maybe you should buy a book on OOP?

Hi,
I am asked to do an user control which takes the input for the PageSize
and PageNumber.The User control also has a button on clicking which would set the PageSize and Page Number of a Grid.Grid is not part of a user control.
If a Page has a Grid control and my user control is registered in it.
How should I be doing this?I need an approach.Do I need to raise an event
from user control which will be captured by the page containg grid.
So that I can do databinding in that by assigning the values of pageSize and Page Index from User Control.
Any suggestions or links would be helpful.
Thanks

It would be impossible to judge the error without viewing ur code....
|
|
|
|
|
<br />
private void Form1_Load(object sender, EventArgs e)<br />
{<br />
comboBox1.SelectedIndex = 0;<br />
webBrowser1.GoHome();<br />
}<br />
this would initialize the combobox way where i can input populate the combobox with serveral pages i like.
when i try with the textbox:
<br />
private void btnEnter_Click(object sender, EventArgs e)<br />
{<br />
wb1.Navigate(new Uri(txtbox1.TextChanged.ToString()));<br />
}<br />

How do I wake a sleeping thread when Thread.Resume is obsolete?
Som
|
|
|
|
|
Make the thread call Monitor.Wait() on a lock variable, then have the waking logic call Monitor.Pulse() on the same lock variable.
MSDN documentation: http://msdn2.microsoft.com/en-us/library/system.threading.monitor.aspx[^]
Example:
<br />
class Threaded<br />
{<br />
private object myLock = new object();<br />
<br />
private void GoToSleep()<br />
{<br />
lock(myLock)<br />
{<br />
Monitor.Wait(myLock);<br />
}<br />
}<br />
<br />
public void WakeUp()<br />
{<br />
lock(myLock)<br />
{<br />
Monitor.Pulse(myLock);<br />
}<br />
}<br />
}<br />

I am developing an windows application in which i have to calculate check digit...
For Example:
Data to be encoded is "21435".
encode: 2 1 4 3 5
Weighting: 5 4 3 2 1
-----------------------------------
Totals: 10 4 12 6 5
-----------------------------------
Then add them: 10 + 4 + 12 + 6 + 5 = 37
Next divide the total by 11 and get the remainder which is 37/11 = 3 remainder 4. The remainder is the check character.
To type encoding the data 21435 that can be scanned, print (214354).
How can i do this check digit calculation on every keypress event of textbox.......
Help me in getting solution.....................

So you want us to code an application in stead of trying yourself and then ask for hint if you really can't figure out what's wrong?
Maybe you should give it a shot...

Hi All,
I am working on FTP uitility using C#. I have build a class for that using C#. But while uploading the file on FTP i am unable to upload whole file on the FTP. Only part of that file is uploaded. I have used the following code to upload the file.
--------------------------------------------------------------------------
public void UploadData(string FTPUri, string FilePath, string FileName, string UserName, string Password)
{
FtpWebRequest reqFTP;
reqFTP = (FtpWebRequest)FtpWebRequest.Create(FTPUri+FileName);
reqFTP.Method = WebRequestMethods.Ftp.UploadFile;
reqFTP.UseBinary = true;
reqFTP.Credentials = new NetworkCredential(UserName, Password);
StreamReader ReadStream = new StreamReader(FilePath);
string ftpResponse = ReadStream.ReadToEnd();
ReadStream.Close();
reqFTP.ContentLength = ftpResponse.Length;
StreamWriter ftpStream = new StreamWriter(reqFTP.GetRequestStream());
ftpStream.WriteLine(ftpResponse);
ftpStream.Close();
ftpStream.Close();
}
--------------------------------------------------------------------------
Here i am able to upload only part of that file. Can anybody tell me what is the problem?
Thanking you.
Pravin

for getting full data without error use binary reader for uploading
like this
//FtpWebReq.Credentials = new NetworkCredential(userId, Password);
// FtpWebReq.Method = WebRequestMethods.Ftp.UploadFile;
//FtpWebReq.KeepAlive = false;
// FtpWebReq.UseBinary = true;
//FtpWebReq.ContentLength = FINFO.Length;
FileStream fsSource = new FileStream(fileName, FileMode.Open, FileAccess.Read);
BinaryReader binReader = new BinaryReader(fsSource);
Stream strm=null;
byte[] byteRead;
binReader.BaseStream.Seek(0, SeekOrigin.Begin);
long pos = 0, fLen = 0;
int buffLength = 2048;
int readSize = buffLength;
fLen = FINFO.Length;
try
{
strm = FtpWebReq.GetRequestStream();
while (binReader.BaseStream.Position < fLen)
{
pos = binReader.BaseStream.Position;
if (fLen - pos < buffLength)
readSize = (int)(fLen - pos);
byteRead = binReader.ReadBytes(readSize);
strm.Write(byteRead, 0, readSize);
}
binReader.Close();
strm.Close();
fsSource.Close();
}

I have developed a Windows Application which embeds "WebBrowser" Control. by default i have loaded one aspx page (which contains one server side button) into the browser. I want to invoke a Click method of this button (not manually) and pass arguments to the button click event. I have used the below code to pass arguments:
HtmlDocument doc = webBrowser1.Document;
HtmlElement btnTemp = doc.GetElementById("btnSubmit");
Object[] args = { "data1", "data2" };
btnTemp.InvokeMember("Click", args);
but i was not able to get these values in my aspx page.
i have also tried the below code:
Object[] args = { "data1", "data2" };
doc.InvokeScript("__doPostBack('btnSubmit',args)");
here is the code for my aspx page:
protected void btnSubmit_Click(object sender, EventArgs e)
{
Object[] args = new Object[] { e };
if (args != null)
Response.Write(args[0].ToString());
}
Can anyone can help me out how to get these values from my aspx page.
