Can anyone help me.

I wanna add a "Settings" feature to a VB app of mine. But would like the settings to be stored in the system registry? How can i rite data to and read data from the registry in Visual Basic 6? I have no idea of how to do this so if you could provide me with the required module(s) it'll be great.

Please

Thanks in advance, i know someone on these forums will be able to help me.

all the stuff beginning with Reg

use a registry module...

Or generally :

use can use

code:

---

GetSetting ( AppName As String,Section As String,Key As String, [Default]) As String

---

But with those you don't really have much control.
If you want more control, use RegOpenKey(), RegCreateKey(), RegQueryValueEx(), RegSetValueEx(), and RegCloseKey().

GetSetting and SaveSetting are ideal for basic saving and retrieving of user options.  ANd you don't need to decalre anything as they are built-in VB commands.

SaveSetting ("MyAppName", "MySettingName", "MySettingValue")


GetSetting ("MyAppName", "MySettingName")

If you want help with the Reg*() functions, don't hesitate to ask. They're not hard to use once you get used to them
For now though, Get/SaveSetting will do you fine

1. If i say use GetSetting to retrive a setting in the registry, how would i put the value retrieved into a variable? eg, into a variable called SettingValue
   
2. If i would like an installer to create default values for a MySettingName, where should this be created?
   [/list]
   
   
   Thanks

Dim value As Variant
value = GetSetting("MyAppName", "MySettingName")

And please don't double-post - edit.

Just beware of using Variants - the lack of type checking can be the source of errors later.

2.  I assume you mean if you're using an insatller such as NSIS or Inno Setup, in which case the path is:

remove the brackets and then it will work fine

No, you need the brackets on that line because you are setting the result of the function into a variable.

You are probably getting errors because you are only passing it two arguements and it needs three.

code:

---

value = GetSetting("MyAppName", ",Settings","MySettingName")

its the keyname you can call it whatever you want, but it obviously has to be the same in both your SaveSetting and GetSetting calls.

If you are saving options then aveing it something like Settings or Options makes logical sense.

yes its the second arguement, 'Section'

RileyM, please look in your help files...
Explaining everything about GetSetting/SaveSetting is too much. And explaining the registry API's is even much more to explain.

Put your cursor on "GetSetting" and/or "SaveSetting" in VB6 and press F1 to access the help files...

Or, in case you have an illegal version you can also take a look at the msdn library which contains all the VB6 helpfiles. More specifically, the Visual Basic Document: Programmers Reference. There you'll find every command, statement, whatever you can use in VB6 with full detailed explanations (just as in the help files; heck, they are the helpfiles, but online).

eg:
SaveSetting
GetSetting
DeleteSetting
GetAllSettings


---------------

As for GetSetting/SaveSetting. This saves data to "HKEY_CURRENT_USER\Software\VB and VBA Program Settings\*". But that registry path isn't much appreciated by many ("professional") people. If you can, don't use GetSetting/SaveSetting as they not only save data in a very obscure place, they also don't provide much flexibility. Use the registry API functions instead, but only if you know exactly what each function does and why and what the restrictions are etc. In other words, you need to know (almost) everything about the registry and its API's. This said, if you are making a private project (one which you aren't gonna distribute) you can do whatever you like of course.

---------------

Also, a very important note on the registry example modules/classes you'll find on the net for VB6. They all are roughly the same (no wonder, they all are copies from eachother without people even checking the API's and their funcionality and ins and outs!!!). They contain some errors and/or some minor glitches and don't always provide 100% compatibily with all Windows versions or even provide decent/correct functionality (yes, and I'm even speaking of the ones you'll find on sites like vbAccelerator, although they are correct for the most part, they often are very bloated... Codes you'll find on PSC are even worse and should never be taken as-is!)...

I say this because some time ago, I searched for some example registry module/class (because I was in a lazy mood). After finding out that everything you find on the net is a copy of eachother I began to wonder and studied the API's and registry and quickly came to the conclussion that all those sources can be optimized a lot and even contained some glitches (note: all this goes for many many... many example sources).
