View 2 RepliesNot sure if I'm posting this in the right area, but here goes anyway. I've been working with sql databases for practice, but can't seem to get around one thing; after I add it as a data source, I can't go back and add tables.
I start off by going through the project, then add item, choose the service-based database, and go from there. I add the tables, then go in and add it as a data source.
After I've added it as a data source, I can go back into the .mdf form and add lines and edit properties, but it wont update in the data sources. So, I can't add it to the form.
I reopened my project to edit it but it is only showing the code not the design I cant get it back how do I do it?
View 3 RepliesI am just testing how to use dll and after googling a lot, I made it work partially...Created new project Class Library, named it myFirstDll and made a Public Shared Sub helloDll to do something. Now since this is my first time, the dll is simply showing the input in a msgbox:
Public Shared Sub helloDll(ByVal msg As String)
If msg <> "" Then
MsgBox(msg, MsgBoxStyle.OkOnly, "WE HAVE SOME MSG")
Else
MsgBox(msg, MsgBoxStyle.OkOnly, "NO MSG")
End If
End Sub
After building the dll-file, I started a new project using normal windows forms, named it "useMyDll", I clicked Project -> Add Reference, and added my dll. The program file that I made needed a textbox and a button for using the dll:
Private Sub useDllButton1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles useDllButton1.Click
Dim msg As String = Nothing
msg = TextBox1.Text
myFirstDll.myFirstDLL.helloDll(msg) 'this will be in msgbox in dll-file
End Sub
And when running this I could write something in the textbox and a msgbox with that input would pop up. Really happy with that. My first attempt to make a dll and use it was very successful. Then I thought, what about running the dll from rundll32.exe? It would be handy to make a dll that could be run without my exe. After googling a long time, I tried to add a new button:
Private Sub useDllButton2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles useDllButton2.Click
'Now let us see if we can open it using rundll32.exe ?
Dim msg As String = Nothing
msg = TextBox1.Text
[CODE]...
Now the first button still works just fine, but the second button gives some error (translated to english would be) like "missing entry: helloDll" I also tried to open with command prompt, same result.
After googling again I read one place that you can't run a visual basic dll with rundll32.exe, so is this true? Or is there some way of doing it? I read one place that it works if you make the dll be "COM-Visible", but I don't really understand how to or what it means. I tried to open properties, clicked Assembly Information, and "Make assembly COM-Visible", but this doesn't change anything. Then I read somewhere that it has to be in a module to work. Could it be that I need to rewrite some codes and it would work, or would I have to start learning c++ in order to accomplish this?
I have this 40 mb (game) file.The only way to change certain lines in it, is using hex editing software.For my program, I need to change a certain texture in this file.But when I use a streamreader in combination with a streamwriter, the resulting file is a lot smaller and when I load it, the game crashes.How can I hex-edit and replace a certain string in this file?(I use visual basic .net express edition 2008)

View 11 RepliesI am creating a Flash fully-animated website for a customer, that reads its text and images from an outsource (on the same web host).They requested an admin page to edit the text and images.I am thinking of making a asp.net page that reads the text file into a dynamic textbox.The user can edit it then save it, so the Flash player would read the new text.
My question is, do I need to create an FTP connection with the authorization username & password?Since the asp.net web page would be on the same server, can it open the txt file and edit it and overwrite it without the need for FTP connection?
I'm looking to take a small snippet out of a wave file which I can do by reading in the headers, calculating time in to samples and selecting that data back to another file with the headers appropriate for the new smaller chunk.
My question though is does anyone use a nice small free library that does something like this. With the numerous different versions of wave files and headers not matching I'm trying not to re-invent the wheel and if someone has done it already and can handle these discrepencies that would be amazing. If not I'll fire up the kettle and get the coffee on.
Ok i know your all denying knowledge of VB6 here but it still exists and people are still stuck with it for now! Plus youre a brainy bunch so i hope you can help, it is more .Net related anyway i think.Ok ive inherited an old VB6 app that needs to access a VB.Net dll and im having issues with it!Ive compiled the DLL and made sure all the Com boxes are ticked so ive now got a .DLL and a .TLB file.
Now when i load up the VB6 app and go to add a reference to the TLB file it makes the reference ok but when i run the app i get a "xxxxx.dll cannot be loaded" error when it hits code trying to use it.What ive tried is running Regasm against the DLL with the regfile option to generate a registry file that i can load onto my machine but it still gives that error.
im not sure exactly how to get a .Net dll into vb6 tbh so im just fumbling my way with it. What i think has happened is a previous version of the DLL was registered on the machine, has since been deleted but the system is still trying to use the earlier one, reference pointers still around?
So my questions are 1. how can i clean the machine out , apart from formatting it!, so i can register the new DLL properly and cleanly on it. 2. What exactly is the right way to get a .Net component into an old VB6 app? I was assuming it was by using the TLB and making a reference to that, it wont let me add a reference stright to the DLL itself.
the problem is I'm trying to access a file that has no file extension. I think you can see why this is so difficult. The specific file I'm trying to edit is the hosts file (C:\Windows\System32\drivers\etc\hosts).
