I have several .txt files (equal matrix, say (200,15) polated with integers) and I need to read and merge them into 1 file (matrix elements aggregated), then this resulting file to be used for loading a grid. Is there any rapid method to do that?
View 8 RepliesI have a class and method exposed to a client asp.net app. The class looks like
<DataContract()> _
Public Class Class1
Private v_string As String
Private v_integer As Integer
[code]....
The method is declared as
<OperationContract()> _
Function GetStuff(ByVal bar As Class1) As String
In the client code I create an instance of Class1 and set the values for v_string and v_integer, but using Wireshark to look at the xml being sent to the server only a value for v_string is being sent as part of Class1. I'm guessing this is because it considers the value of v_integer to be null/not set. Here is an example of the client code.
Dim MyService as New Service1.ServiceClient
Dim test as New Service1.Class1
test.P_integer = 1

how different types are passed/used since Integer is a intergral type and String is a class, but can't seem to work out what to do to fix the problem.
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

How to merge 2 pdf files into 1 pdf file using vb.net. Couldn't find a method to do it.
View 1 RepliesI need to create a software that it merge many GIF File into one file container.My application has this form I want that when i click "Add File" it shows an OpenFileDialog and that add file's path in the ListBox.
View 1 RepliesFor 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.

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 RepliesBasically I have and array of integers that vary in size. I need to compare each number to each other number and display which number is repeated. For example:
Dim ints() As Integer = {1,2,2,5,4,6}

How can I run through the array and compare each integer with the numbers in the array. I tried a for loop but it didn't return the value I was looking for.

I have several combo controls that need to be populated with a specific ID and name. I want the user to choose the name and have the ID in the background. Later when the data is exported from the database the specific ID's are exported and not the names.
I see that I can create the items in the combobox rather easily using their names. However, how can I associate the ID number for each of the items. Private Sub frmReceipts_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
' Add receipt types to combo box
cboReceipt.Items.Add("Monetary")
cboReceipt.Items.Add("Inkind")
cboReceipt.Items.Add("NSF")
End Sub
I thought it would be better to have a seperate table with the different receipt types and then somehow connect/link the contents of this new table to the combo box on this form. However, I am at a loss on how to do this.

I tried binding a DataGridView to a DataSet using the DataSource property but no data appeared in the DataGridView. I placed a DataGridView in an empty form, making no property changes except for the name. I did not create columns in the DataGridView. In the form's load event I placed the following code for loading a dataset named ds Executing in debug mode, I confirmed that there was data in that dataset. No column headings or data appeared in the DataGridView. What am I doing wrongly? There are 34 fields (columns) in the DataSet - maybe it exceeds the capacity of a DataGridView.

Is this the way it can be done? I believe this is the case, but can't find any definitive examples online (probably not searching properly)
