 Hi
Can anyone please tell me how can I convert a dataset into foxpro dbf file.
C, I have a grid which is associated with a dataset. There are options of exporting grid data to differenet format, like pdf, xml, excel etc. This grid provides the feature whereby all mentioned format's file can be created.
There is one more requirement of exporting the grid data into foxpro dbf.
Please let me know if anyone has an idea regarding this
Thanks in advance -

No... Because it's very dependant on your implementation of OCR. How does your implementation learn what a character image looks like? (Don't answer, I'm not really asking...) Don't know? Start digging into neural networks...
Look, if you want to write an OCR application, it's not as simple as pasting together code snippets from various apps and articles. There is no one method of determining the boundries of paragraphs, sentenances, words, and characters. This is something you going to have to do A LOT of research on before hand and then come up with your own implementation and design your app with the features you want to support and that you NEED to support based on your requirements.

This is a piece of information for serious mobile application developers who tired of writing complicated code that runs only in one platform.A new language for creating mobile applications for PDAs is out, it is so simple that after programming in codewarrior and J2me this language will seem like childs play to you. Not only is it simple but the applications built using this tool run on all platorms ranging from PALM, POCKET PC, SYMBIAN,NOKIA . The language - GBasic comes bundeled with simulators for all platforms , IDE and sync server for for developing server side sync logic . The mobile application development tool is called GoDB.

He joined CP yesterday and posted two messages, both exactly the same. The contents of the message just describe a product, no real question was ever asked.

Hello first of all its a SHE not a HE. Secondly is it so bad that a person shares a piece of information about a new product with others . If you dont find it interesting then its not my fault. But there are others who have been mailing me and want the link to the product they want to know about the new products in the market. Like it was mentioned in my thread the information was ONLY for SERIOUS programmers. So if you do not belong to this category then please IGNORE.

I'm as SERIOUS as the next guy/gal. But instead of posting your AD in the Forums for free, why not SUPPORT this site and PAY to advertise on it, like other SERIOUS vendors.
[EDIT]
Opps! I forgot to include the link to the MediaKit[^]

Hi,
I'm not ease with the multithreading and i have a lot of difficulties to understand how a program run with this kind of things.
What i want to do :
1- My class will be accessed by multi - threads and than thread safe
2- Allow a connect and disconnect and reconnect (the reconnect occurs only when the socket is closed by the remote host or an error occurs)
3- When a user want close the socket all tasks made by threads will stop (Race condition to avoid)
4- Will be Synchronous and very efficient.
My problems :
1- (See point 2 and 3 before)
a) We can imagine that a thread close the socket (user action) and at the same time i lost the connection and than my receive thread or send thread or both will raise an error or close event also. Than It could be occurs that the error or close event come from the application launch a reconnect but the user want to stop.
b) the user call a connect juste after an error occurs and the reconnect is started but not finished. We can imagine the connect from the user is managed before the reconnect or it won't be possible.
c) and all the others cases that i can't not yet imagine.
-->I think taht all these problems are caledl race condition
Please help me it's very important and very urgent.
PS : Sorry for my poor english but it's not my natural language. All advices on my coding are welcome:
The code is to large to be posted. If you think you can help me. Ask and i will send you the class that i made

I've got this cute little vbn ap I put together that I wanted to be able to run on someone else's PC. I tried to move a copy of the thing over there but it wouldn't recognize the file extensions.
I thought for certain that as long as someone had the .NET framework, they would be able to run an ap, but this does not seem to be the case.
Is there an easy way to use Visual Studio .NET to pack up an ap so it can be installed on a PC with just the Framework?

Your (vbn == VB.NET right?) application should have a .exe extension. What are the extensions of the files you are copying?

Yes, you can add an installer project to your solution. Then tell the installer project what needs to be installed and build it. You will end up with some files that can be used to install and uninstall your application.

I copied the entire folder containing the files because I wasn't sure which were required and which where not. As it turned out, the exe ran fine, it was just that none of the file extensions were recognized by the PC with just the Framework and SDK .
The price of making .NET so "universal" seems to be all these associated files. It seems that a self-extracting windows installer containing all the necessary files in a compressed format would be useful, (whether or not it is practical is another matter).

Certain files, like source code files, debugging information files etc. don't have file associations with them on them if you just install the .NET Framework because there are part of the development environment which is not intended for deployment.

It depends on what you are building. It is perfectly possible to build a fully featured application that just has one EXE file without anything else (other than the .NET Framework itself).

So long as the target computer has the same version of the .NET Framework that you developed the app on and you copied over the .EXE and all of it's support files (.DLL's, .OCX's, .BMP's, .config, ...), it'll work. You might have other prerequisites, like updating MDAC on the target computer.

I suspected as much. I was able to get the ap to run just fine, but the file extensions are not recognized by the machine, even though I installed the framework and the SDK.

What file extensions? You said that you copied the .EXE file over and it didn't run. What else from the 'bin' folder did you copy over? And what file(s) are you trying to open by double-clicking on them?

I'm not clicking on any of the file extensions. I just noticed that they all have that default "Windows doesn't know what kind of file this is" icon. I thought the framework would at least pass the associations on, but perhaps it is too compact to include them. The executable still executes however.
I copied over the entire bin because I was not certain which files I absolutely HAD to have in order for the executable to work.

Ahh... That's because the .NET Framework doesn't register a handler for those extensions. Those are done by the Visual Studio IDE. The files you need are project dependant. You'll definately need the .EXE's and the .DLL's from the bin folder of your project...

The ap in question is from Michael Halverson's Visual Basic Step-By-Step. It's the "Lucky 7" slot machine program.
Frankly, I would love to try using the installer option, but having little experience with it, I am uncertain as to how to properly configure it.
I would want for it to check and see if the user has the correct version of the framework installed, and if not, direct them to the URL to install it first.
From there, it would do what most Windows installers do- recommend a spot on the C drive, create the folder if none exists, ask the user if they want to view the "readme," and ask the user if he/she wants a shortcut on their desktop.
Of course I suppose it would also have to include an icon in the Start-->Programs, and an uninstaller tied into the Add/Remove programs as well.
I know enough to be dangerous, but not enough to accomplish all of this...yet.

Thanks for friends that reply my post before....
I am binding a picture box to a path... It works fine if the path is valid. Problem comes when tha path is invalid or empty...
The code that is red highlighted is where the error come out..
Private Sub BindFields()
Try
Dim b As Binding = New Binding("Image", objDView, "CoverSample")
AddHandler b.Format, AddressOf MyPictureBox_FormatImage
[B]picBook.DataBindings.Add(b)[/B]
Catch ex As Exception
MsgBox(ex.Message, , "BindFields")
End Try
End Sub
Private Sub MyPictureBox_FormatImage(ByVal sender As Object, ByVal e As ConvertEventArgs)
Try
If Trim(e.Value.ToString) <> "" Then
Dim fi As New System.IO.FileInfo(e.Value.ToString)
If fi.Exists() Then
e.Value = Image.FromFile(e.Value.ToString)
isValidPath = True
End If
End If
Catch ex As Exception
MsgBox(ex.Message, , "MyPictureBox_FormatImage")
End Try
End Sub

You didn't specify what the error was or where it occured. There was no highlighted text anywhere.
But, I see a problem with the way your trying to validate if a file exists or not. Check to see if the desired conversion if valid before you try and validate that the file is there, which could be done much simpler.
Private Sub MyPictureBox_FormatImage(ByVal sender As Object, ByVal e As ConvertEventArgs)
Try
' Check to see if this is a valid conversion.
If Not e.DesiredType Is GetType(Image) Then
MsgBox("FormatImage was called with the DesiredType of " & _
e.DesiredType.ToString, , "MyPictureBox_FormatImage")
Exit Sub
End If
' Check if the file exists (assumes "Imports System.IO").
' Uses the Static version of the Exists method.
Try
If Not File.Exists(e.Value.ToString) Then
MsgBox("File not found: " & e.Value.ToString, , "MyPictureBox_FormatImage")
Exit Sub
Else
' The file exists, try to create an Image object out of it.
e.Value = Image.FromFile(e.Value.ToString)
End If
Catch ex As Exception
MsgBox(ex.Message, , "MyPictureBox_FormatImage")
End Try
End Sub
