thanks for that suggestion, it helped to know more about printing.
But it doesnot say anything about how to use no of pages selection (ie. FROM PAGE, TO PAGE) . I have enabled the print dialog and also the selection but was not able to print the specified pages even if i told to print (EXAMPLE FROM PAGE 1 : TO 2 PAGE), instead its prints all.
Thanks again

Datagrid ??

Hello,

I have a datagrid with a bound datatable. I want to edit one or two columns of the data. When I set the readonly property of the datagrid to false then I have row to add new data, and this is not allowed.
Also after the inpu of the data I have to calculate a value for another column in the grid.
Datagrid = Code, Description, Price excl tax, Tax (%), Price incl Tax.
So when the user changes the price excl then I have to calculate and show the price incl (depending on the tax) or if the price incl is changed then I want to show the calculated price excl.

I'm still working with VB.NET 2002

What errors are you getting? I would start by assuming that this is some kind of access issue. Does your process have rights to crate files in the folder where you are trying to create files?

Ok, without an error this is going to be next to impossible other than guessing you know.

Ar you perhaps catching an exception and not displaying it? Is the library catching and not displaying an exception?

Anyway, the first thing I would do is make sure that the ASPNET user has at least create and write access to the folder where you are trying to write the files to. If it does not, set that up and see if it helps.

VB6: compression problem

-- NA --15-Dec-05 0:14

15-Dec-05 0:14

Hi all, don't know if anyone can help with this obscure question. I'm currently busy with a project (for school) involving data compression. We'll only work with plain text files which makes life simpler. The problem: a way to save space we came up with is to chop off one bit off each byte, because for character codes < 128 only 7 bits are needed. I've written code that does this, it converts an input file in chunks of 8 bytes, except it corrupts data (half). Here is the code I'm using:

Compression:

file_name = cdsave.FileName<br />
file_length = FileLen(file_name)<br />
fnum = FreeFile<br />
ReDim bytes(1 To file_length)<br />
Open file_name For Binary As #fnum<br />
    Get #fnum, 1, bytes<br />
Close #fnum<br />
Kill file_name<br />
For i = 1 To file_length Step 8<br />
    txt = vbNullString<br />
    txt2 = vbNullString<br />
        For isub = 0 To 7 'bytes to process each time.<br />
            If file_length < i + isub Then Exit For<br />
            txt = txt & Right$(Format$(Dec2Base(bytes(i + isub), 2), "00000000"), 7)<br />
        Next isub<br />
        For converttxt = 0 To 6<br />
            txt2 = txt2 & ChrW(Base2Dec(Mid$(txt, (converttxt * 8) + 1, 8), 2))<br />
        Next converttxt<br />
    fnum = FreeFile<br />
    Open file_name For Append As #fnum<br />
         Print #fnum, txt2;<br />
    Close #fnum<br />
Next i<br />

Decompression:

txt = vbNullString<br />
txtInPhase = vbNullString<br />
<br />
intEndFile = FreeFile<br />
<br />
file_name = txtFile.Text<br />
file_length = FileLen(file_name)<br />
fnum = FreeFile<br />
ReDim bytes(1 To file_length)<br />
Open file_name For Binary As #fnum<br />
    Get #fnum, 1, bytes<br />
Close #fnum<br />
If Dir(cdSave.FileName) = cdSave.FileName Then Kill cdSave.FileName<br />
For i = 1 To file_length Step 7<br />
txt = vbNullString<br />
txt2 = vbNullString<br />
    For isub = 0 To 6 'bytes to process each time.<br />
        If file_length < i + isub Then Exit For<br />
        txt = txt & Format$(Dec2Base(Format$(bytes(i + isub)), 2), "00000000")<br />
    Next isub<br />
    For converttxt = 0 To 7<br />
        txt2 = txt2 & ChrW(Base2Dec(Mid$(txt, (converttxt * 7) + 1, 7), 2))<br />
    Next converttxt<br />
fnum = FreeFile<br />
Open cdSave.FileName For Append As #fnum<br />
     Print #fnum, txt2;<br />
Close #fnum<br />
Next i

What happens to the data:

Input: Hello. This is a test string for demonstration purposes.
Output: Ollo. Thigpis a tesq|string for OemonstrOtion purgses.

If someone could take some time to look at this I'd be immensely appreciative. I don't expect anyone to do my work for me, and don't worry, the deadline is still far away. Smile | :)

Change the ChrW() in the above lines to use Chr(). the ChrW() function returns a Unicode character which is mucking up your algorithm.

No problem! Your question is one which we are happy to answer - you have thought about the problem and provided your code, and asked nicely Smile | :)

It's a pleasure to help.

I would look into the various articles on the internet that show you how to store an image into the DB and do the same thing for the document.

basically just reading in the file as a stream of bytes and storing that data into the DB field then getting the data back out and writing to disk again.

Use Ctrl+Left/Right to switch messages, Ctrl+Up/Down to switch threads, Ctrl+Shift+Left/Right to switch pages.
