cpp code convert to visual basic 6 - Visual Basic Discussion Boards

Am in the middle of developing a window app when i got stuck.the tools used are as follows combobox,numericbox,textbox and a radio button.Actually what i wanted to achieve is small inventory.Meaning that whenever i click on the value in the combobox as against that of numericbox it will automatically subtract from stored values.
Pls help me out tanks

could you be a bit more specific?
perhaps show a bit of code to where you get stuck or witch error you hang on.

Okay so go right ahead, you have my permission. Please come back and ask questions when you get stuck.

Why is common sense not common?
Never argue with an idiot. They will drag you down to their level where they are an expert.

It would be somewhat like this:

Private Sub myCombo_SelectedIndexChanged(sender As System.Object, e As System.EventArgs) _
                     Handles myCombo.SelectedIndexChanged
    Me.myNumeric.Value += CDbl(myCombo.SelectedIndex)       ' add index value
End Sub

hai guys..
i am having trouble with vb.net..please anybody tell me that how to copy a file to system directory. while i'm tried to copy using the command "file.copy", it is says "you need administrative privilage to access system directory"..
thanx in advance

If you do not have an administrator account then you cannot do it. If you do have an administrator account then modify your program's properties to run as administrator, as described here[^].

speaking as ...

Thank you somuch

i didn't see any question, you are asking us to convert for you? Confused | :confused:

C++ to VB6?

VB6 has been deprecated, meaning that there's only minimal support available. Next to that, VB6 does not facilitate all that's possible in C++.

Compile your code using watcom or whatever and link to it - and stay away from VB6. There's no new technology created using that technology, since there's no place left to buy a new compiler. It "might" run on Win8 with some tweaks, but there's a good chance that the support will be cut in anything beyond Win8.

Hi,

At my work, I have to test a Visual Basic application. I don't have the code source.

Often I get runtime errors. When I get one, I try to understand what is the cause before I contact the developer. Often it is a runtime error.

I want to know if a tool can give information about such errors without having access to the code source.

Any suggestions?

Thanks,

Claude

Hello,

Try this[] one

In an ideal world, you'd have a file, generated by the app in debug mode, that mentions all the steps that you took before the exception occurred. That way they have the steps to reproduce the bug.

..and it might be caused by something totally unrelated Smile | :)

Have you considered requesting the code? What is the app created with? In .NET we call them usually exceptions, I'd associate a "run time error" more with classic VB.

Hello everyone I am a beginner to programming with vb.net. Currently I am creating a notepad like application in VB (just for learning and practice). I want to make an installer for it (by using external installation creating utilities) so that I can give it to my friends just like any standard application.

But I have just confused that how I will decide that which files should be placed in installation with the .exe file. Can any one help me, that which other files are needed to properly run the application.

Also currently I am creating the application with visual studio 2005. I don’t have much knowledge about dot net framework. So how can I decide that to someone whom I am giving my application have required dot net framework. And if they don't have than how I can give it to them.

One more thing, is their any windows version (like XP, Vista, 7 etc) related limitation to consider, in order to properly running the application. If yes then please explain it too.

Any other suggestions are appreciated.
Thanks

you can find it here, goodluck. Laugh | :laugh:

No friend, I already have idea about it.

What I want is to collect all the files which are required to run my application, put them in other folder, and then create a installer by using a external installer creation utility. (I don't want to use visual studio's setup and deployment wizard). (I request you to read my about post ones again). Now please give me required suggestion. Thanks for your time.

You should know what your app requires to run. After all, you wrote it!

But, as a general rule of thumb, from the files in the Bin\Release folder, you don't need:

*.vshost.*
*.pdb
myApplicationName.xml

Everything else, you probably need.

I have a vb6 application that contain various drop down menus.
Some user has not permitted to access some menus.
For the purpose Logged in as administrator and list all menus in the application and select a user and check or uncheck whether this user access that menu.
But how can I list all menus in the application without manually enter menu name ? Because when we add new menu in the application, I manually add these menu name in list. And If menu no is 100 or 150 then it is difficult to enter the menu name or control them. So I want the code for list all menus in the application automatically. Please help me.

I'm a little confused to where you refer to drop down controls and drop down item. but the item once can be done pretty easily by code

VB

dropdownbox.items.add("object, a string as name for example")

with a loop and some if/else statements you should be able to filter what you add by the users permissions.

Enumerate all objects of type "Menu" in the form and add it to a list from where an administrator can decide to grant permissions.

For instance:

for each myControl in myForm.Controls
  if typeOf myControl is Menu then

and so on...

<pre lang="sql">Ok. thats working.

Then my next doubt is how can I identify main menus and sub menus</pre>

I'm starting in my intro to programming class. New to this side of computers. My teacher isn't much help so I"m falling behind. Can't get rid of the errors in my code. Pseudocode is supposed so simple from what I hear. If someone can help me do a simple program with this algorithm that would be awesome. Thanks a lot.

Pseudocode is simple. It's supposed to be. Pseudocode is not program code!

Funny, I do not see an single error in any of the code that you posted.

mainshotime wrote:

A simple program using what algorithm? You have not posted one word about what it is that you are trying to do.

We are not teachers here either. You will probably not find one single person here willing to do your homework for you. If you get into trouble, then we can help. Post the code that you are having trouble with and ask a clear, concise question and I am sure that someone will be able to help you.
