i want to set the datatime picker visible and unfold at once when the user clicks on a button,up to now i can onlt set visible true/false only, what is the event i should call to unfold the datetime picker

There isn't a specific method call to do this. I suspect you can achieve it using a window message of some kind. But I don't know which one.
Look at the DateTimePicker class in reflector. You need to trigger the WmDropDown method (which is private).
This is called from the WmRelfectCommand method, which is called from the WndProc method.
You can use SendMessage[^] to transmit messages to a controls message queue, which will be processed by WndProc.
Maybe some else knows what message values you need to transmit. It's likely to be a base message + the WM_REFLECT message. http://www.tech-archive.net/Archive/VC/microsoft.public.vc.language/2005-08/msg00589.html[^]
Sorry I can't be more helpful.

Track the window message for mouse down ans mouse up and check if the active control is datetimepicker. If it is then do as required. I hope this helps.

Where can I download "msword.olb"

Google ? I'd guess it's either part of Word or part of the Word toolkit.

Hi all,
im having a problem with retrieving a binary file from the database and reading it in my code, so far i have this:
byte AttachmentByte = new byte();
AttachmentByte = StringToByteArray(inputString);
and a function to convert it:
public static byte[] StringToByteArray(string inputString)
{
System.Text.ASCIIEncoding encoding = new System.Text.ASCIIEncoding();
return encoding.GetBytes(inputString);
}
but when i run it i get the error:
Cannot implicitly convert type 'byte[]' to 'byte'
can someone please tell me what im doing wrong.
thanks in advance!

StringToByteArray returns byte[] while AttachmentByte is defined as byte.

Hi guys,
thanks for the quick replies,
the problem is that i tried using:
byte[] AttachmentByte;
then it gives the error on the filestream:
using (System.IO.FileStream fs = System.IO.File.Create(newPath))
{
fs.WriteByte(AttachmentByte);
}
i get the errors:
The best overloaded method match for 'System.IO.Stream.WriteByte(byte)' has some invalid arguments
Argument '1': cannot convert from 'byte[]' to 'byte'
is there something else im missing?

Yes. A good C# book.
Seriously, the error message you got is self explanatory. It has some invalid arguments. Look at the documentation for that method and see what arguments it expects. BTW, this some different code you are showing than the one given in the original post.

thanks once again for the reply, i know that i posted other code...im trying to retrieve a binary file stored in the database and write it to my local machine, with use of creating a folder and using a filestream.
thanks for all the advise

WriteByte writes just a single byte to the stream but you need to write byte[] so use the overload that writes byte[] to the stream. That's it
|

Hi Giorgi,
sorry but i have never used filestreams or binary files before, how would i go about using the overload that writes byte[]?

As suggested by Navaneeth you need a good C# book. As for FileStream, you can have a look at its method at this msdn link: FileStream Methods[^]

hi,
in my application i need to upload the data to the serevr using ftpwebrequest method .I need to upload 2 files one is a zip file (more than 10 MB) and other is a text file to the same server. when iam uploading total zip content is not getting uploaded to the serevr and its returning error like
" The underlying connection was closed: An unexpected error occurred on a receive." So please can anybody help me where exactly the problem is.Is that the problem with the code or serevr settings.
Thanks in advance
Here is my code
private static void Upload()
{
string[] strar = new string[] { sourcepath + ".zip", sourcepath + ".txt" };
foreach (string str in strar)
{
FileInfo fileInf = new FileInfo(str);
string uri = "ftp://" + ftpServerIP + "/" + fileInf.Name;
FtpWebRequest reqFTP;
// Create FtpWebRequest object from the Uri provided
reqFTP = (FtpWebRequest)FtpWebRequest.Create(new Uri("ftp://" + ftpServerIP + "/" + fileInf.Name));
//Set the proxy to null to get around the "the requested ftp command is not supported when using http proxy" error
reqFTP.Proxy = null;
reqFTP.Timeout = 2000000000;
// Provide the WebPermission Credintials
reqFTP.Credentials = new NetworkCredential(ftpUserID, ftpPassword);
// By default KeepAlive is true, where the control connection is not closed
// after a command is executed.
reqFTP.KeepAlive = false;
// Specify the command to be executed.
reqFTP.Method = WebRequestMethods.Ftp.UploadFile;
// Specify the data transfer type.
reqFTP.UseBinary = true;
// Notify the server about the size of the uploaded file
reqFTP.ContentLength = fileInf.Length;
// The buffer size is set to 2kb
int buffLength = 2048;
byte[] buff = new byte[buffLength];
int contentLen;
// Opens a file stream (System.IO.FileStream) to read the file to be uploaded
FileStream fs = fileInf.OpenRead();
try
{
// Stream to which the file to be upload is written
Stream strm = reqFTP.GetRequestStream();
//mydelegate delinstance = new mydelegate(Writedata);
//int result;
//Stream strm = reqFTP.BeginGetRequestStream(null, null);
//Stream strm = reqFTP.BeginGetRequestStream(delinstance,result);
// Read from the file stream 2kb at a time
contentLen = fs.Read(buff, 0, buffLength);
//progressBar1.Maximum = contentLen;
// Till Stream content ends
//progressBar1.Step=10;
while (contentLen != 0)
{
// Write Content from the file stream to the FTP Upload Stream
strm.Write(buff, 0, contentLen);
contentLen = fs.Read(buff, 0, buffLength);
//if (progressBar1.Value < progressBar1.Maximum)
// progressBar1.PerformStep();
}
//progressBar1.Value = 0;
// Close the file stream and the Request Stream
strm.Close();
fs.Close();
Console.WriteLine("Uploading completed for file " + str);
}
catch (Exception ex)
{
Console.WriteLine(ex.Message, " Upload Error");
Console.ReadLine();
}
Console.ReadLine();
}

1. Don't use caps lock while posting a question.
2. Don't request something, just as nicely
3. Look at KeyPressed event of textbox or use Google to find more help.

Use masked textbox.

I am creating a folder watcher application.
If a new powerpoint file gets added in the folder it should get started automatically.
So if I put .pps file into the folder then and I say
System.Diagnostics.Process.Start(fullPath);
it works fine.
This is not the case with .ppt files
Only the powerpoint application gets started not the slideshow.I want the slideshow to be started.
I have done some R & D and found that Microsoft.Office.Interop.PowerPoint will help and done something like this
Microsoft.Office.Interop.PowerPoint.Application ppApp = new Microsoft.Office.Interop.PowerPoint.Application();<br />
ppApp.Visible = MsoTriState.msoTrue;<br />
Microsoft.Office.Interop.PowerPoint.Presentations oPresSet = ppApp.Presentations;<br />
Microsoft.Office.Interop.PowerPoint._Presentation oPres = oPresSet.Open(e.FullPath,<br />
MsoTriState.msoFalse, MsoTriState.msoFalse,<br />
MsoTriState.msoTrue);<br />
But this is also doing the application open not the slideshow, does anybody have any idea?
Also I want rest all powerpoint presentations gets closed and only currently added powerpoint application gets started as slideshow.
Thanks in advance,

I'm not sure how possible that is. If double clicking doesn't open PPT, then PPT is not responding to being passed the application as a command parameter.

Thanks for quick reply,
I am not very much clear with your answer.
Actually I want the ppt application start automatically when it gets placed in the folder under watch.

Assuming you have a FolderWatch watching on the folder, when a file is placed in the folder, run Process.Start("YourPPTFileName"). It will open the PPT file in associated application.
