Try
Dim sourcePath As New System.IO.DirectoryInfo(tfcrtfdir.Text) 'rtf selected folder
Dim targetPath As New System.IO.DirectoryInfo(tfctxtdir.Text) 'txt selected folder

I'm creating a program in VB.net that does the following:At a high level I receive a file in email, put the attachment in a monitored folder, import the text file to excel, format the excel, and then email the excel file to a list of recipients.
Here is my plan:
Completed: Outlook VBA to monitor all incoming email for specific message. Once message is received drop attached .txt file in a specific network folder.
Completed: (VB.net) Monitor folder, when text file is added begin processing
Not Complete: (VB.net) Import text file to Excel
Not Complete: (VB.net) Format Excel Text file.(add in a row of data,format column headers with color/size, add some blank columns, add data validation to some of the blank columns that allow drop down selections)
Completed: (VB.net) Save file.
Completed: (VB.net) Send file to list of recipients.
Obviously the items above that are not complete are the bulk of the work, but I wanted to get some advice on what some of you think would be the best way to approach something like this. The import and formatting of the file are causing me some problems because I just can't decide what would be the most efficient way to do this.
The way stated above. Import to excel -> format Having a template excel that contains all of the formatting already done for me and attempting to transition the data to this document (no clue if/how I can do this). Is it even feasible? Have the template already created and then import the text file to a new excel file, then transition that data to the excel template?
Something I thought about, in terms of formatting the document, was to record a macro of me doing all of the formatting that I'm going to need and then attempt to convert that macro into my vb.net code, but I'm not sure if that will work. I will need to verify that the text file comes in the EXACT format every time correct?
I'm recreating an old 16 bit game. I'm creating the chat normally displayed at the bottom.Each sentence transitions in character-by-character.Every time a character is added, I wanted to have it make that little bleep noise. I've got a wav file that contains a short 'blip' that sounds just right, problem is, when I have it do the blip every time, it usually messes up.
View 1 RepliesI'm having some problems with a Windows Application where I have deselected the application framework to be able to use Sub Main().I want to use Sub Main() because then I can do some things without showing any graphic interface to the user. Things such as automatic update and checking if another instance of the application is running.After checking these things, I execute these lines to run my application:
vb.net Dim frmMain As New frmMain() Application.Run(frmMain)
I need to run it this way or else the application will close when Sub Main() ends. The Application.Run keeps the application alive until I exit the main thread.However, this causes some problems with a variable, no information can be saved into it, I don't know if it affects any other variables as I haven't noticed it. However, I save a string to the variable and then when trying to compare it, the variable is string.empty.Could it be Application.Run which is messing things up? Should I do frmMain.Show() and keep the application running with some sort of WaitUntilExit?
The problem I am running into is the OpenFileDialog box. I am allowing the user to pick an image and I want to save the image location into a column in the database(this isn't the problem), I know how to get the image location and save it...The main problem is this. Each time I open up the "OpenFileDialog box" and choose an image, it remembers the last location used, but after the image is chosen, the program looks at the images location as the spot the database is...To sum this up: Each time I use the "OpenFileDialog" and choose an image, the program looks at the images location for the database instead of in the "Debug folder" (which is were I put the database) So i end up getting an error that it can't find the database. Everything usually worked fine until I used the "OpenFileDialog"...

The problem I'm having is that whenever I have selected a keyword that has synonyms, or in other words, whenever a keyword is selected that populates the datagridview, and at the same time I try to close the form or remove the keyword my form gets messed up.
View 2 RepliesI have an error when converting a text string to date, I've tried all the date conversions I can think of and still get the same error (cdate, date.parse and Convert.ToDateTime) this happens after I export an RDLC report to a PDF. As you can see in the below code, there are 2 identical variables called newDate1 and newDate2, one being declared before the render and the other being declared after the render. The first one works no problem but the second one I get the error: Conversion from string "16/02/2011" to type 'date' is not valid. This now becomes a program wide error and affects every date conversion done in the program, this problem remains until the program is restarted.
In short: CDate converts MM/DD/YYYY no problem, but after a PDF export it tries to convert to DD/MM/YYYY which gives an error
Public Function ExportPDFReport(ByVal ReportPath As String) As String
Dim newDate1 As Date = CDate("16/02/2011")
Dim bytes As Byte() = uxReportViewerRDLC.LocalReport.Render("PDF")

View 2 RepliesIm designing a program that will read from various text files (preferably RTF files) and then put them into the RTF box in the program when a button is clicked.
Here is the portion of my code that i am referring to.
Try
Dim fileText As String = My.Computer.FileSystem.ReadAllText("c:\" & selectedHero & ".rtf")
infoDisplay.AppendText(fileText)
infoDisplay.Rtf.Format()
Catch
MsgBox("Selected Hero currently has no File with us.")
End Try
Now heres the problem. In the file i have a few pictures and its formatted and what not. I thought since its a RTF file and the Box is RTF it would auto format.... but anyways. It appears like this in the RTF Box.
{\rtf1\ansi\ansicpg1252\deff0\deflang1033{\fonttbl{\f0\fswiss\fcharset0 Arial;}}
{\*\generator Msftedit 5.41.15.1507;}\viewkind4\uc1\pard\f0\fs20{\object\objemb{\*\objclass Paint.Picture}\objw3000\objh3000{\*\objdata

On a image file (PDF), the OCR has recognised the picture and text. However on Visual Basics, how do you search for a text on this image file? The primary goal is to allow a text search (i.e POxxxxx) on all the image files (PDFs). The returns of the search will be the assciated image files where the text (i.e POxxxxx) is found on.

i have an old VB6 system that generates plain text files. When this old system writes "A" into the file, it writes (hex) "41". For an "ä" (a-umlaut, special gernam character), it writes (hex) "E4".
Now i have to process files like this in VB.Net. when i open such a file in the IDE, it displays correctly "ä" (But not always!). To see what i mean, please open a notepad and create a new file "ae.txt" with content: äöü. Now your file contains exactly 3 bytes: (hex) E4 F6 FC.
But when i write code like
Dim strTest As String
strTest = File.ReadAllText("ae.txt")
Debug.Print(InStr(strTest, "ä"))
i get 0 - so i cannot find back the "ä" - what do i need to do, to find it? And 2) for compatibility reasons, i have also to be able to create such files. How to do that? Seems the different encoding types do not work as i think.

I'm doing a project where we are re-creating a very old system.The client wants the same base functionality and some improvements.One of the things I'm currently working on is the note-system. These are used as flags of some sort, but are also used as a comment field for some products or client profiles.In the old system you could write the text and save it like you would get in a .txt file. They want the new one to be able to do word formatting such as:
Different font sizes (Only some parts of the text)
Different font colours (Only some parts of the text)
Underlining of words
Bolding
Italics
Tab-spaces
Those are the specs they want. What I need to know is the following:
1) How do I do that?
2) Currently they store all these files on the server as text files and the database have paths that refers to each file. I want to be able to save a text file with that formatting to the HDD of the server like in the old system.
3) If possible I would like to save that text to the database with the formatting.

View 3 RepliesWith regard to RichText, obviously information is contained somehow with regard to the text colour, font, size as so on and as it supports more than the ASCII character set such as Unicode characters and so on.
Now I know that Microsoft Word .doc and .docx files contain such information.
My question: How to extract just the rich text information only and ignore all the formatting
information such as bold, underline, italic and so on. How can this be achieved with VB.Net
What I am thinking of here, is, imagine a CSV ( comma separated value ) file but in Rich Text Format.
In relation to this, does Notepad only support a limited character set, i.e. ASCII only?

I am building a vb.net application with VS2010. The aim of the application is to change sln. files from VS2005/2008 versions into VS2010.I am using a Form with 2 text boxes and 2 buttons. When I click the 1st button it reveals the sln file in the text box. Then i have a 'convert' button that I want to use to 'convert' the file that appears in the first text box. I have come quite far with the source code but am just a bit puzzled as to how i can retrieve the VS2005 sln files and to get the 'convert' button to display the text in the 2nd text box.[code]
View 5 RepliesI current have an app that I am trying to create. I have 2 List boxes, a textbox, and a command button.What I am trying to do is take about 100 text files that all have certain text in them that I need to change at run time to whatever I put into the textbox. For instance Each Text file has my old company name and I want to be able enter my new name into the textbox and click the command button and the app will open each text file, find the text that I specify and replace it with my new name then save the file into a specified folder.What elements should I be studying to make this happen? So far this is what I've come up with:
OpenFileDialog - to open the file
StreamReader - to read the text files and find the text that I specified
**Not sure on the replace method**
StreamWriter - to write the text from the textbox to the new file
SaveFileDialog - to save the file to the specified location
