Datagridview - Porting A VB6 Application With Msflexgrid
Mar 17, 2009I am porting a vb6 application to VB.net. One of the key forms has a large msflexgrid on it - about a 1000 columns and 50 rows. It has 2 header rows - the first header row has merged cells to form a main header and the second row has sub headings. There is no requirement for any data entry and it's unbound. The code does the work in deciding what to display (if anything) in each cell. It is solely used to display data in the form of a character and a coloured background and to display a tooltip text with more information when you mouse over it. Works beautifully in vb6. I'm trying to decide whether to:
a) use the vb6 msflexgrid in the .net version
b) use the datagridview - which at a first glance seems to have a problem merging the cells on the header row
c) build my own custom control to do the job

View 1 RepliesDetect If The Application Is A Console Or WinForms Application?

View 5 RepliesVb6 Migration - Porting A .bas File To Vb?
Feb 21, 2011I'm working on some legacy VB5/VB6 code and need to convert a ".bas" file to vb.net. i found several options
Compile the .bas file into a com dll and then reference and use it in my project. (For this I guess I would need vb5 or vb6 which I don't have at my disposal) Copy and paste the contents of the file in to a new module in vb.net and then try solving the errors one by one.The contents of the .bas file reference a particular dll. The .bas file has mostly declarations consts, types, sub's and functions.
What would be the most elegant way of redoing this in vb.net. Is it as simple as option 2.EDIT
I used VS2008 express and ran the code through the upgrade wizard it did the necessary conversion. and the .bas file was converted to .vb. I took that file and decided to rewrite other parts of the code, including some redoing of the converted .vb file. Other questions related to this one are here.

View 3 RepliesC# - Language Choices When Porting A Classic Asp App To .NET
Sep 7, 2010We are looking to port our existing classic ASP application to .NET, but we're unsure of what language to use for the new app. I personally would 'prefer' C#, as I'm more familiar and comfortable with that languages way of doing things, but, the original code is VBScript, so it would possibly be easier to port to VB.NET ... One possible situation I fear would be that, because the code is so similar between the two variants of VB, that we might end up getting stuck on something that is not similar between the two, even though it looks like it would work. A shift to a wholly different language might avoid that kind of situation. Does anyone have any practical examples of this kind of situation? Insights to illuminate the issue with? Do the potential benefits of a complete paradigm shift outweigh the gains from a high degree of 'copy-and-paste-ability' ?
View 9 RepliesForms :: Toolbar Question - WRT Porting From VB 6?
May 16, 2009I've got a VB 6 application that I ported over to VS 2005. The application has a toolbar on it. When building it in VB 6, I created all the bitmaps for the toolbar. And they looked just fine.Now I have ported to VS 2005. The toolbar works just fine. But the images in the toolbar look "wrong". The best way to describe them is if you took each bitmap and squeezed it down to about 67% of it's size. So it is missing the detail it used to have. And the smalleer picture still takes up the same amount of space on the toolbar. It is just that each squeezed bitmap now looks like it has a thick, blank pictureframe around it.

.net - Window Close Events In A Winforms Application?

My application currently has a boolean flag, that is set to True on textchanged event. So I will only need to check for the boolean value in whatever event is trigger by the red box.
Can't Distribute Winforms Application That Writes To Event Log
Feb 3, 2012My application writes to the event log if there is an error or other status updates.
The application checks to see if there is an event source named "applicationName"and if not, it creates the source (see code below).
This works fine if the user is an administrator.
If the user is not an administrator, an error is thrown when SourceExists is called:
{"The source was not found, but some or all event logs could not be searched. Inaccessible logs: Security."}
In my environment, the typical user is NOT an admin. Therefore, I cannot use the event log in my application.
Is there a way around this, or is the event log effectively useless for distributed applications?
Embed HTML Code Into A WinForms Application?
Jul 21, 2010I've a somewhat unusual feature to implement and I don't know if it can be done without much effort.A WinForms application has a help file (well, not HTML help, but simply a HTML file with a reference sheet).

The client wants this HTML file to contain buttons/checkboxes which a program should respond to.For example, if a user clicks a HTML button in the help file some value should appear in a textbox on the main form, etc. Is it altogether possible

View 3 RepliesPassing Data From WinForms Application To MVC3
Dec 14, 2011I am working on an application that has a Winforms and MVC3 Web component. We need to be able upload large files from the desktop to the web. I have tried the various VB 2010 WebClient and FTP FileUpload alternatives but continue to run into permission issues, even though the User-ID and password I supply are the same as those used by an FTP application that successfully copies files to the same MVC3 site. In my efforts to find alternative solutions, I have looked into using WCF which also seems complicated and problematic for this particular application.
The closest I have come to a solution utilizes HttpWebRequest on the Winforms application. The following VB 2010 and C# code (MVC3) successfully passes the Filename and File data to MVC3 (the InputStream contains the references and UrlEncode data, but the class containing the fields for this data are null. (I have also passed just the file data without the filename, and the uploaded file is successfully created from the InputStream - but the method variable is still null). Although I could pick apart the InputStream, I would prefer a more elegant alternative.
VB 2010 Winforms method:
Public Shared Sub FileUpload(ByVal Filepath As String)
Try
Dim Host = System.Configuration.ConfigurationManager.AppSettings("Host")
Dim url As String = Path.Combine(Host, "UI/FileUpload")
Dim request As HttpWebRequest = HttpWebRequest.Create(url)
request.Method = "POST"
