For some reason the last PDF file to be written to the "final document" is the only PDF File that is visible when the "final document" is open. However, all of the bytes are accounted for in the file size...so for example: file1 = 60 bytes and file2 = 49 bytes. The final document has 109 bytes but only contains file2 when viewed in the pdf viewer.

I'm trying to copy multiple excel source files into one excel file. My current code is working only for 3 source files..If more than 3 files are there, it doesn't copy the data but creates blank work sheet in the output excel file. Lets say I have a source folder with 5 excel files. Each workbook contains one worksheet with data. It copies upto 3 worksheets along with data into output excel file.
Lets say excel1 contains A as work sheet, excel2 contains B as work sheet ,excel3 contains C as work sheet ,excel4 contains D as work sheet ,excel5 contains E as work sheet .Now my output excel file should look like..OutputExcel with A, B, C, D, E along with respective data.But my current code is giving output as A,B,C worksheets along with respective data but its creating blank sheet1,sheet2 in place of D & E.

I'm trying to merge 2 files - a 'simple' string replace. 2 files - an ini-style data file that has <descriptor>=<value> with about 70 rows created by web-form and database, and a csv template file with 2500 rows that has 12 fields, but the values will either be in fields (4) and (5) OR (6) and (7). The data fields won't always be in the same order. I'm reading a line from the Template file, then looping through the data file looking for a descriptor match then replacing it with the value, but because they are in pairs per line, I have to loop twice; then loop to the next template file and so on. Then cleanup to remove the unused descriptors.
I have been unable to crack this for about a week. I wrote a VBScript version yesterday in about an hour and it worked flawlessly first time taking 2 seconds to produce the csv output file exactly as required.
Tried reading the data file and looping through the template, tried almost every combination of Using/End using; For/next, Do Until, Do while, etc. Used Streamreader, File.ReadAllLines, I've read msdn till I know it by heart, but no use. You name it, I've tried it. Must have missed something or it would work though.
You are my final hope. The problem part of the code is below...
BTW -
srXX = StreamReader
swXX = StreamWriter

View 7 RepliesIn the old dos days you could combine 2 files as save to a third file:copy file1 + file2 file3. It still works in a dos shell. I did this: Shell("copy " & file1 & " + " & file2 & " " & file3)I got an error that file3 cannot be found. I know it doesn't exist I want to create it. So I created a bat file:copy %1 + %2 %3 and called it as such:Shell("ccopy " & file1 & " " & file2 & " " & file3). I still get the error that file3 cannot be found. First I don't see how it can tell from the shell that file3 is a file. How do I do this otherwise? Do I have to create a blank file before calling it?

View 1 RepliesI have two text files. The first text file has the format:
ID h1 h2 h3
a 1 5 7
b 3 3 5
c 0 4 8
And the second file:
ID h4 h5 h6
a 2 4 9
b 3 6 1
b 4 1 5
Now I want to merge two files. The output likes
ID h1 h2 h3 h4 h5 h6
a 1 5 7 2 4 9
b 3 3 5 3 6 1
b 4 1 5
c 0 4 8
The two files has the same rows and columns. For the first rows(except header) in the two files, they have the same first column. Therefore just a simple append. The final first row becomes
a 1 5 7 2 4 9
The question is in the first only has one
b
and the second file has two
I want the maximum count of items from each list in the resultant list. I put some white spaces after "b" then append strings.
b 4 1 5
For key "c", because it is only in the first file and not in the second file, so I append white spaces after the corresponding strings.
What i need exactly is to make a program that have a button called "browse" , when the user clicks it , it prompts the explorer and let the user choose a .exe file, then theres another button called "merge", when the user clicks it, i want the file that was already selected to be merged with one that will be already on my project, and the result would be a single executable file, that will open the 2 .exe files when running it. Obviously i could do all the steps, but im stuck on the file merging part.
View 4 RepliesI used backgroundworker to receive file segments from a server, it taking the segments and save them directly to a binary file. the problem is,I using a global variable to store the "FreeFile()" number.when "backgroundworker" receive "START" it do F = FreeFile()
when it receive "Segment", it should append to that file, but the problem is ... backgroundworker no more recognize the file (which its identifier saved in global variable F) and telling "Bad File"?!
whats the soultion?I think about opening the file and close it each time (not leave the connection to the file available). But I didn't figure out how to append to Binary files, It always replace their contents. and If I use "Append" option it corrupt the file!
i tried out this [code]i can create and write in the .bin file but how to read it then?

I am trying to make a program in Visual Basic 2010 that should do the following:
-Open file as binary
-Start with position 57 and read the following characters until a 0 is found, print the whole name
Inside the binary file, all the files' names end with 0 (which should not be printed), example:
B000000.dat0
eft.dat0
G000000000.b70
For the above examples, the names that should be printed are B000000.dat, eft.dat, G000000000.b7 respectively. The code I wrote is below. The problem is that i am not sure how to read the name until the 0 is found since the names are variable in length and so are the extensions(dat, b7). Also some names have 0 in them which makes things difficult.
Using gs As New FileStream(fileName, FileMode.Open)
gs.Position = 57
Using gr As New BinaryReader(gs)
For x As Int16 = 57 To 70
Dim textvar(x) As String
textvar(x) = gr.ReadChar
text3 = textvar(x) & (gr.ReadChar)
Next
End Using
End Using

Is this the correct way to go about this problem? If not, how should I attack it?
I wrote some software in Vb6 a long while ago and this program creates a datafile. This datafile stores variables like doubles, ints, arrays etc, using the Get/Put methods from VB6. This all worked great for vb6.I am now starting to rewrite this tool in .net and find that the binaryreader as well as the other fileopen methods do not convert the doubles correctly. So as I rewrite the software I still want to read the old datafiles just like before.if I use a byte array and read 8 bytes, the bytes read are identical in Vb6 and vb.net. We are talking about reading an existing old binary file created by vb6.
for example the number 3, stored as a double has a 8 byte array that looks like this:
[0][0][0][0][0][0][0][5] in vb6.
in vb.net if you use the bitconverter.getbytes(cdbl(3)) you get
[0][0][0][0][0][0][8]64]
in vb6 the first array is converted to the # 3 correctly.in vb.net the array is converted to something way way off.
