File I/O And Registry :: Using The SaveFileDialog To Save Listbox Info Into A Text File?

Mar 17, 2010

I'm using the SaveFileDialog to save listbox info into a text file. The files save fine, but when you go to save the file, if you hit the cancel button, it will overwrite the previous file you saved, because it's name was the same and it seems to save the previous file as the new name for your next file. Is there any way to catch if the user clicks cancel, and then exiting the sub if they did?

Large Multidimensial Array - Write A Program To Do Markov Chain But States Are Quite Large

Jun 9, 2011

I want to write a program to do Markov chain, but my states are quite large. First of all I calculate all the transition probabilities and revenues for all states(1381860 total states), and store in a multidimensional array. Public RevArr(0 To 9, 0 To 750, 0 To 282) As Long

After that the iteration of markov chain should use these as inputs to calculate the steady-state probabilities. But when I try to run the main code I got this error.Exception of type 'System.OutOfMemoryException' was thrown.

The following is the declaration of second array I add just another dimension for storing all the iterations, but I get this error. Dim stateprob(IT + 1, 0 To 9, 0 To 750, 0 To 282) As single

Getting SaveFileDialog Error

Apr 14, 2010


This code works on my local machine (Windows 7 Ultimate).When I tried it on WindowsXP,it didn't even open the dialog,instead it gave me an Unhandeled Exception error.

I can't remember the specific details of the error,but I do recall my profesor telling me there could be something wrong with permissions(me being the ONLY user on my machine,and his machine having multiple user accounts).

But what does all that have to do with opening the SaveFileDialog?

Could it be that SaveFileDialog1.AutoUpgradeEnabled = True is causing the problem?

OpenFileDialog And SaveFileDialog?

Mar 6, 2012

My users need to browse to select a file and then save it to a different location. Here's my code I've got so far - it incorporates the OpenFileDialog to open the file and the SaveFileDialog to save the file. When the code goes into the OpenFileDialog portion, it works great....the initial directory is set to "C:" This is where the user will select the file they want to save to another location.

Savefiledialog 1.1 To 2.0 Conversion?

May 25, 2010

I have an .net 1.1 framework application I would like to update to 3.0 framework (or at least 2.0), but I've just run into a real problem. The savefile dialog code which works fine in 1.1 does not work in 2.0 and up. Line for line the code is the same (thereis no difference in line numbers at all). I'm baffled.With the exception of throwing an error for the Quicktime 7 control, VS2008 indicated no errors in converting 1.1I open my 1.1 (VS 2003) version and step through line-by-line. Works as advertised.I open my 2.0 (VS 2008) version and step through line-by-line. Appears to be working, dialog opens fine, I enter a filename, code continues; but when complete, there is no file in the folder.I'm wondering if the problem lies in the block of code for the small XML file I'm writing.

SaveFileDialog Substitution Variable?

Jul 30, 2011

I have not tested this, but I am fairly certain it would not work.When my program installs, I want to ensure that the default SaveFile directory is into a directory under the program's directory.For example, if the program installs to C:Program FilesConcept VisionsWorldFileMaker, I want the SaveFile dialog to default to C:Program FilesConcept VisionsWorldFileMakerWorldFiles.I can see in the File System of the setup project, under the property 'DefaultLocation', it's value is:

[ProgramFilesFolder][Manufacturer][ProductName]With Manufacturer = Concept Visions and ProductName = WorldFileMaker, am I correct in assuming this would be C:Program FilesConcept VisionsWorldFileMaker on a default Windows machine?

Below is the code I use to open the SaveFileDialog to save the file. The line in bold is the line I have my question about. How do I get the saveFileDialog1.InitialDirectory = "C:Program FilesConcept VisionsWorldFileMakerWorldFiles" without actually hard-coding it as "C:Program FilesConcept VisionsWorldFileMakerWorldFiles"? I want to use a substitution variable similar to "[ProgramFilesFolder][Manufacturer][ProductName]".

Eventually, I want to learn how to allow the user to install in a folder of choice. If I am correct, I would need such a substitution variable.

Saving Images Using SaveFileDialog?

Jul 1, 2011

I am attempting to save a graph that I have displayed on the screen as an image file (e.g., a jpeg file) but the image I want to save has additional information such as axis labels that are not displayed on the screen. In addition, I also want to suppress some information that appears on the screen.

I create a separate bitmap canvas called mycanvas and I recreate my display on this canvas with the additional information. When I save it with an image format such as iftype=system.drawing.imaging.imageformat.tif with the command,iftype), I get the image file that I created on mycanvas. But If I use the SaveFileDialog followed by,iftype) I merely save the image displayed on the screen. It is as if my graphics object has reverted back to the graphics object I was using for the screen display.

Save A File Data Using The Savefiledialog?

Feb 27, 2011

I was trying to export a data from the listview control into an excel format and I was able to make it successfully using a command button directly. I want to use a SaveFileDialog to export and save the content of the listview. I searched from MSDN website and got a sample code which was originally intended for saving an image file. I tried to used it and edit the code and combine my code to export the data content. It ran successfully and attempt to export the data in an excel format but when you open the file in the path as to where you save the data, it gives you a message "Excel cannot open the file 'Filename.xlsx' because the file format or extension is not valid. Verify that the file has not been corrupted and that the file extension matches the format of the file." and it just leaves an empty excel file. I read from the MSDN site that if you are using an MS Office 2007, the file extension for excel would be '.xlsx' and not 'xls'. Let me give you the two codes I tried to use. First, I used command button and was able to successfully export and save the content in an excel format but using the SaveFileDialog was not successful. I suspected that there's something wrong within this line 'oBook.SaveAs("saveFileDialog1.FileName.GetType()")' and 'Dim fs As System.IO.FileStream = CType _(saveFileDialog1.OpenFile(), System.IO.FileStream)'.

Here are the two diffrent codes I used:

'Using the command button-----successful
Private Sub Button3_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button3.Click
Dim oExcel As Object
