Now I want to create folder on FTP server and then upload multiple files into it.

It's done just about the exact same way to uploaded a file. Just change the Method of the FtpWebRequest object you create, then execute it with the GetReponse method.
Dim request As FtpWebRequest = DirectCast(WebRequest.Create("ftp://someurl"), FtpWebRequest)
request.Method = WebRequestMethods.Ftp.MakeDirectory
Dim response As FtpWebResponse = DirectCast(request.GetRseponse(), FtpWebResponse)
Debug.WriteLine("MKD response: " & repsonse.StatusDescription)
response.Close()

I am able to upload and download single file using demo on this URL -
http://www.codeproject.com/cs/internet/SimpleFTPDemo.asp
I converted that code to VB.Net
But now I want to upload and download one complete folder which may contain sub folders.
So i want to know how to download complete folder

You have to download the files one at a time, and also see what subdirectories are in there, navigate them in your code and download the files in those, one at a time.

Hello,
If you have image in a Rich Text Box, you may use following line of code to save it with image-
RichTextBox1.SaveFile("C:\FileWithImage.rtf", RichTextBoxStreamType.RichText)
You may save this data directly to RTF file using .rtf extension. This rtf file can be opened in MS Word or can be loaded in RichTextBox again using LoadFile method.
I hope this helps .
-Dave.

That is NOT how to pass parameters! You are passing a security nightmare. That code is riddled with injection into the SQL making it extremely vulnerable to a SQL Injection Attack.
SQL Injection Attacks and some Tips on How to Prevent Them[^]
Try something along these lines
SqlCmd.CommandText="spr_ADB"
SqlCmd.CommandType=CommandType.StoredProcedure
SqlCmd.Parameters.AddWithValue("@branchCode", txtBranchCode.Text)
...
It still isn't perfect as you don't validate the text before passing it to the SQL Server, but it is a start in the right direction.

Guys this f*** .resx is always my proble since i migrate from vb6 to vb.net.. every i use another computer which i can't avoid.. because i work on my client and at the same at office i end up with .resx error... what really .resx means..
|
|
|
|
|
What's the error??
.resx files are used to store resources that get compiled into your .EXE. You may have a corrupted form or project.
|

Sir Dave may it cause by copying one object from one for to another.. because i always do it.like copying toolstrip, menustrip, combo, etc.. is it right to do it that way? Should i need to create new object that in need in every new form i made?
|
|

|

What you're doing shouldn't corrupt the .resx file. But, then again, if you don't have the latest service pack installed, there's no telling. You might be forced to recreate the form from scratch. Do not copy the controls from the old form, but drag and drop new ones. You can copy and paste the code form the old form though.

I have a multi-threaded app where objects are enqueued by one thread and dequeued by the other (for sanity sake I'll call them the writer and reader threads).
The writer event is externally triggered and it is imperative that the trigger event is not delayed (which is why it is in its own thread).
There is an AutoResetEvent that is set to tell the reader thread that there are events to read. The problem is that if another writer event occurs while the reader is processing the queue it gives a System.InvalidOperationException: Collection was modified; enumeration operation may not execute.
So - two questions:
(1) Is there a better architecture for this kind of situation
(2) If not, how do I prevent the error - i.e. how can the writer tell the reader to give is a rest for a while because more writing is going to be done?
(I could give code but it'd probably just confuse matters...)

Yes.
:: Use the Dequeue method instead of looping through the queue.
:: Lock the code that is queueing and the code that is dequeueing, so that they can't occur at the same time.
:: Only lock the code that is dequeueing the item, not the entire loop.
When you are using data in more than one thread, you have to use locking to prevent data corruption. The error message you are getting is because the collection has a built in protection that has detected that you have changed the collection in one thread while looping it in another.

I am populating an Grid for a db and one of the fields is a bit field called attachments. I would like to populate an attachment icon if the value is 1.
Thoughts......

Are you asking how to display an image in a DataGridView column instead of the value of the column??
Which version of VB.NET are you using?? Are you using a DataGrid or a DataGridView control??

when am deleting a control from panel am getting flickering i add suspendlayout and performlayout eventhough it is getting.How to avoid this
|
|

Which version of VB.NET are you using??
You might want to try turning on doublebuffering for the form the panel is on. What happens also depends on what you're doing with this panel. Why?? What's the thing for??

Hi everyone.
I´m doing an application with an MDI form, a button bar (toolstrip) and few child forms.
I made these forms of a specific size, and I want them to be that size, fixed borders, but when I opened them as MDI childs, they are enlarged, even though I set the maximum size in the size I want. If I set their size by code before opening then, the borders are resized, but the controls in it are kept as if it were larger.
One more thing, I tried 3 forms, the 3 are enlarged, but to different sizes.
Why is that, I just want my Forms the size I set them!!
Thank you!

Change you child forms FormBorderStyle property to FixedSingle.
|
|
|
|
|
I did that.
Anyway I found something, had to change AutoScaleMode property to None. It still changes the text size of some controls, but in can work on that.
Thank you

And?? It works fine for me. Everything stays the exact same size as when it was defined in the Designer.

The onlt way I can replicate what you're describing is to set the Size property of the form on creation, resetting what was done in the designer.
Quite literally, all i did to get it to work was create an MDIParent form and a child form. Set the child forms border style, have to code create about 10 cihld forms at runtime. Worked as expected. There was no change in the size of the forms and no way to resize them.
