I am creating a shell for a FORTRAN application which reads a tab delimited text file.Because I am using Excel to manipulate data, is it possible to use the Excel Automation features to "save as" a tab delimited text file?The only method available seems to be a unicode text format, which does not work. Or is there another format that mimics tab delimited so that the FORTRAN application will read such a file without difficulty?
View 1 RepliesI have an asp page with vb.net code that will query a database and present the user with the number of records that exist that need to be exported along with a button to export them. After you push the export button, it will prompt for a location and filename. But after that, it will not refresh the page with the new counts that now exist. Or in this case update the count to zero for the button they clicked.
[Code]
So how can I tell the page to refresh with the new counts. It almost seems like I need to tell the process to wait until after the user has finished finding the location and saving the file but I don't want to add a generic threading.thread.sleep in, I want it to only wait until they are done and then refresh the page.

I've wrote a program awhile ago that prints barcode labels. The old version needed the font to be installed in the fonts folder, but that made it a pain for people using the program for the first time, as the program would print the barcode label with a default font. If I load the font file directly and try and print, it just shows up with the default font, obviously not a barcode. The following doesn't seem to work:

View 5 RepliesI have my datagridview being loaded from a Text File and then being saved to a text file as a comma separated file - the commas obviously separate the columns. However in some of the cells prior to saving, I have data that i have inputted over two lines by pressing shift + return.
E.g.
"SOLD
10/05/2012"
This saves fine, but obviously shows up in the text file as a line break, which then causes some issues when I choose to re open the info back into DGV. How I can code so that it saves as a line break within a cell, rather than a completely new line.
i just found a new error problem on my app.. i have a save button that saves text1. as the file name and text2. as the content.. i recently tried to save this file name on my app: HKEY_LOCAL_MACHINESoftwareC07ft5Y as a file name, and due to the in the file name, it made my app error and close without being able to save my file.. my question is, how to bring a msgbox saying "invalid characters in file name" instead of causing it to error and shut down.

I'm developing a very simple app that does nothing more than launch two other apps. I'm developing this under the .NET 2.0 framework for WinCE 5.0 in VS2005.No matter what I do, I keep getting file not found exceptions not handled, and the program crashes. (Yes I should probably have a try/catch block, but this isn't the issue.)
Here's some code
fullPath = Path.GetFullPath(drivePath)
Me.Label1.Font = New System.Drawing.Font("Tahoma", 6.0!, System.Drawing.FontStyle.Regular)
Me.Label1.Text = fullPath & strDrivePath
Now, the label change here is not important, I only do this to output the full path of the directory, and strDrivePath is "whatever.exe"
If Directory.Exists(fullPath) Then
If File.Exists(fullPath & strDrivePath) Then
Me.Label1.Text = "EXISTS!!!"
[code].....
The irritating thing is after getting and displaying the full path (I know it's there) I check with the first IF to prove to the program it's there. No problem.I then use the second IF to prove to the program that the executable is there, and change the label output on screen to prove to myself the code is executed. The label changes. The file is there.
Then when I run the program, File not found exception. It's driving me insane. I've tried in multiple OSes (Vista and CE 5.0), I've tried in directories with spaces and no spaces, I've tried using Process.Start() and setting up the file details through the info command.I've tried putting a path in there directly instead of using variables. I've tried wrapping the whole kit and kabodle in quotes like this Shell("" & fullPath & strDrivePath & "" ) and like this Shell("""" & fullPath & strDrivePath & """").I've searched high and low on forums around the globe, including multiple threads here and I just cannot get it to work.

I created a VS2010 application that stores data in xml files with a custom extension (e.g. ".ABC") I would like to be able to open an .ABC file and have the application launch with the specific file's data loaded. This is analogous to opening a Word doc and having Word open with the doc loaded. I have searched for a while but can't even think of a phrase that explains this process. Nothing seems to match "You know . . . that thing that happens when you double click on a data file".

I'm BASICally wanting to know what I should look into for saving multiple variables of a custom class object to be loaded later. I've seen some things about text, and I can do that fine, but don't think it would be the proper/best way of handling things
at all. I also saw some talk of XML, SQL tables, etc. I just need a point in the right direction.
For a bit more info on my actual project, I was tinkering with a 'simple' program to allow users to create rooms/objects/etc., which will then be converted into Inform 7 language (an interactive-fiction language).The variables needing stored are objects with a number of string variables and integer variables. I need to be able to save those, then load them out later into an array of said objects.
For anyone needing a more VISUAL image of what I mean, here are a few screenshots to show you what I mean. Also, if anyone has ever used Adrift, it is (at the moment) very similar to it, but for the Inform language.

I have a form with an Adobe PDF reader control. I point to a specific PDF I want to load when a button is clicked. The PDF is 28 Megs big and takes some time to load into the reader. I would like a progress bar to to show (like a showdialog kind of thing) so the user does not click all over the place and thinks the app is static.
The PDF reader is loaded like this:
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Me.AxAcroPDF1.LoadFile("c:Section3.pdf")
End Sub
How would I update the progressbar1 control to reflect the time it takes to load? I checked the AxAcroPDFLib Namespace and found no "progresschange" type of functions or events.
I have no problem loading the contents of a text file into a richtextbox(rtb) with the below code. I can then edit and save the contents of the rtb to the file, and clear the rtb.
However, is the file still open? Does loading a text file into the rtb actually open that file? I am asking because I can't find any methods or techniques to close a file that has been loaded into a rtb. Is clearing the rtb the correct procedure?

In my userform I have a WebBrowser control to load PDF files. I have added a FolderBrowserDialog to allow user selection of drives and or folders.
What I am trying to do now is after a file has been selected and viewed, the user may want to change drives and or folder locations. How do I remove the current contents of the WebBrowser control to be a blank screen (just like when the app starts, its blank).
When we use system.io.ReadLines the content of the file should not be loaded to memory right? say I want to create a function. The function accept a string, say "post.txt" where post.txt is a large file (3G) I want to put the first 100k line of post.txt on post.txt and the rest on reserve_post.txt
View 11 RepliesI'm in the process of adapting a current program that I've created to automate it. **Current State***User selects an excel file and the contents are loaded into a DataGrid User can select which environment to run their query against (stage/prod) Program completes processing and updates datagrid with new values User can export datagrid to excel What I'd like to do is centralize the program on one computer and have it monitor a network folder for creation of a specific file type (*.xls or *.xlsx). If one of these is created in that folder then I want to add that file to a queue for processing. Once done processing I want to send the results as an attachment to an email to the user that created the file. After a file is processed I would like to remove it from that folder as well (into a diff folder of completed items).
