There is one 3rd party control called DSOFramer.cab from Microsoft only, you can load all office components in to it as excel, word etc.
I guess it should be free from micro soft site, check with that.
As it is developped by Microsoft it will work only on IE.
If you want any more components similar to it, you can go for Aspose an Australian company product. But with aspose everything is good it is browser independent, but the problem is you have to define the template document and then fill the data by using code. You can define the template structure by using aspose code.
Try with which you find convenient.
Thanks,
Aleem Mohammad.

Hi All,
I got solution to this...My code is,
Imports System.IO
Imports System.Runtime.InteropServices
Dim FilePath As String
Dim objWord As Object
Dim objDoc As Object
objWord = CreateObject("Word.Application")
FilePath = ("C:\Documents and Settings\Administrator\Desktop\Resume2.doc")
objDoc = objWord.Documents.Open(FilePath, , True, , , , , , , , , False)
objDoc.Select()
RTB.Text = objWord.Selection.Text
objDoc.Close()
objWord.Quit()
It shows my .doc file into RTB.

This works, but you lose all the formatting and bullet points. All you're getting is the unformatted text, nothing else.

How can I say get the first x cells in an excel sheet where all you know is the row?
Ie get sum of first x cells starting at cell y?
|
|
|
|
|
I'm not sure what you're after, but using Rows method you can select an entire row. For example:
Application.ActiveSheet.Rows("1:1").Select
After that you can iterate through the Range object using Application.Selection.
Hopefully this gets you forward.
The need to optimize rises from a bad design.

I have a process whereas I need to save a string from a textbox to a temp file and then hashing the file via SHA1. I have that handled but when I create the file and write the data to the file
"08 39 01 62 30 21 12 69 09"
it is written in ascii and I need it written in hex as is. So if you opened the file up in a hex editor you would see "08 39 01 62 30 21 12 69 09" with the ascii as .9.b0!.i. .
Currently I am only getting 30382033392030312036322033302032312031322036392030390D0A
as my hex string in the hex editor and obviously hashing that value will not match the hash of h08 h39 h01 h62 h30 h21 h12 h69 h09
Thanks for any and all help.

A quick look at an ASCII table reveals that you have "08 39..." as a string variable. So of course when you write the string to the file, you get the string in the file. If you want to store the bytes represented by the string, you will need to parse it yourself. I would start with String.Split and Byte.Parse with a parameter of System.Globalization.NumberStyles.AllowHexSpecifier and a BinaryWriter.

Hi Dave.. The code which i use to decompress the file is given below.. Am getting the error "Magic number in GZip header is INCORRECT".
dim source_file as string = "c:/Compressed.txt"
dim destination_file as string = "c:/Decompressed.txt"
Dim sourceFile As FileStream = File.OpenRead(source_file)
Dim destinationFile As FileStream = File.Create(destination_file)
destinationFile.Close()
Dim ms As New MemoryStream()
Dim zipStream As New DeflateStream(ms, CompressionMode.Decompress)
Dim decompressedBuffer(3500) As Byte
System.IO.File.WriteAllBytes(destination_file, decompressedBuffer)
'end writing
'Because the uncompressed size of the file is unknown,
'we are imports an arbitrary buffer size.
Dim buffer(4096) As Byte
Dim n As Integer
Using input As New GZipStream(source_file, _
CompressionMode.Decompress, False)
Console.WriteLine("Decompressing {0} to {1}.", source_file.Name, _
destination_file.Name)
n = input.Read(decompressedBuffer, 0, decompressedBuffer.Length)
destination_file.Write(decompressedBuffer, 0, n)
End Using
'Close the files.
source_file.Close()
destination_file.Close()

Sorry Dave.. I gave the old code .. Below u can find the latest code i use. In the below code.. am getting the exception(Magic number in GZip header is INCORRECT) in line
n = input.Read(decompressedBuffer, 0, decompressedBuffer.Length)
'Compressed File path
dim comp_file as string = "c:/compressed.txt"
'File to which decompressed contents has to be written
dim dest_file as string ="c:/decompressed.txt"
Dim sourceFile As FileStream = File.OpenRead(comp_file)
Dim destinationFile As FileStream = File.Create(dest_file)
destinationFile.Close()
Dim ms As New MemoryStream()
Dim zipStream As New DeflateStream(ms, CompressionMode.Decompress)
Dim decompressedBuffer(3500) As Byte
System.IO.File.WriteAllBytes(dest_file, decompressedBuffer)

This is a bit of spaghetti code, it's a little hard to follow. But, from what I can tell, you're trying to decompress a normal text file, which won't work and would explain the error you're getting. We can't really tell because we don't know the contents of "C:\compressed.txt". Also, forward slashes, in Windows, are used to denote command line paramters, not file paths. I suggest getting into the habit of specifying filepath with backslash's, "\".

Hi.. thanks for suggesstions.. can u suggest any code that i can use to compress and decompress a text file.
|
|
|

I dont' have any and don't have the time right now to create an example.
You've got the basic building blocks. You just need to examine your code, and especially the documentation on the zip stream classes, and lay out what you need to do, step-by-step. Just work on compressing a text file to another file first. Once that's done, then you can worry about uncompressing it.

source_file should be sourceFile. You cannot have a string where it is requiring a stream. Same thing applies to destination_file and destinationFile. These are not the cause for your exception, but are a cause for your code not to compile.
You might want to have the following:
source_file.Close()
destination_file.Close()
prior to your attempt at decompressing the file and outputting. This will ensure the buffer is getting flushed and the test compressed file has all of its data written.

RegSvr32 is used to register COM components, but it your case, it may not work. If this is an .EXE COM server, then the ojects it exposes may not be available at all until your start that .EXE. You won't be able to set a reference to that servers exposed classes, so you might end up using late-binding to get at them. This is not a preferrable situation for someone who is only starting out in C# or VB.NET.
BTW, you asked a question about C# in a VB.NET forum...

You'd be better off asking in the C# forum.
