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.

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.

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 It's a pleasure to help.

Wow, thanks very much, seems to be working pretty much fine now.
Should think about that sort of thing next time; always these stupid little problems. I thought it must be an off-by-one error

:-Dhello,
can anybody tell me how to store ms-word document into a SQL-SERVER 2000 (datatype for the column could be image or varbinary)

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.

I have a panel with a number of different coloured graphics shapes and I was hoping to be able to click on a shape and retrieve its colour.
Is there any way of doing this?
Thanks
|
|
|
|
|
How are your graphics shapes created? Are they separate objects? Are they created at design time or run time?
Assuming that the graphics shapes are objects that have their color as a property, you could have an event handler that handles all of the objects onClick events. In this event handler, you would examine the Color property of Sender.
If the objects don't have a color property, pehaps you can store the color in the tag property.
I hope this helps.

Thanks. These are just drawings (circles, rectangles [DrawRectangle] etc) which are drawn at run time on a panel. When they are created I choose a colour to classify them and the easiest thing would be to click on the drawing and to test the colour attribute of the point that was clicked.
There are some pretty simple ways around it but I thought that clicking a point and retrieving its colour would be straightforward and that I was missing something.
Cheers

I'm looking for a solution to get the process name running an application. For example, i open a word document to generate a letter. The expected result is WinWord.exe.
I'm using VB .Net for my development.
Very much appreciate if can show me what is the API to use and the sample code.
Thanks a lot.
