Private IniFileName As String

Private Sub cmdget_Click()
Dim Temp As String * 50
Dim lpAppName As String, lpKeyName As String, lpDefault As String, lpFileName As String

Dim ret As Long
lpAppName = appname.Text
lpKeyName = Keyname.Text

lpFileName = IniFileName

ret = GetPrivateProfileString(lpAppName, lpKeyName, lpDefault, Temp, Len(Temp), lpFileName)

If ret = 0 Then
Beep
Else

Here's a sample project that deals with ini files: http://www.vb-world.net/demos/ini/

There are lots of resources available at VB-World. Just do a search for "ini files" in "All VB-World" and you will find many pages.

nooooo! dont use ini files, use the registry - much easier and more secure.
u dont even need to call api
look up :
GetSetting
SaveSetting
in msdn.

Hi,casparas.
Here is a link: http://visualbasic.miningco.com/libr...a121998.htm?id

I saw this link a while back on a previous post(can't remember where)... It includes some good information.. It lists all of the API calls and gives examples of how to use them. http://skyscraper.fortunecity.com/tr...api/index.html

Hope that helps...

Storing and loading info from API FILE??? What about the API viewer? That will show you all of the info you need (at least to start)

another helpful resource was originally introduced by Bruce McKinney(author of Hardcore VB); it's the win32 type library. He has since given up the development of this tlb to peet morris of TMS(The Mandelbrot Set) who, with his colleagues have taken the type library to a new level. The TLB and IDL source code(if you're in to writing type libraries) is freely downloadable here: http://www.themandelbrotset.com/html/typelib.html
...just drop it in your windows or system32 directory and then select it from projects>references in vb. it's very cool, very easy to use and encapsulates most of the win32api. I do wish however, that some of the other api's are added to the type library sometime soon.

Kenny: What's wrong with using ini files? Security is not an issue; windooz is not secure anyway, and secure info you want to save, you better not save with SaveSetting either. I like ini files.. their gone when the program is uninstalled, and the bigger the registry gets, the slower windooz gets (and after installing Visual Studio my registry is 10mb already...)

[KENNNY]

yeah, but reg is still a bit safer than using ini, and say some fool was playing around with files on a pc, and happened to delete the ini file your app needed? the person using your app wouldnt be too happy. whereas with reg, its unlikely someone qho doesnt know a lot will be bothered to go start>run>regedit
anyway u can delete your reg settings
also, it can be quite secure if u encrypt them too

Thanx everyone

If you want really good code,go to the
Planet Source Code. It has source code for Visual Basic, Java and C++. Their site is...

[KENNNY]

except a lot of the code there doesnt work
and u have to spend 1/2hr fixing it

So why are you a coder then ?
Just to copy somebody else his/her code without trying to find out how the code works ?

I see a lot of people who just copy some sourcecode and complain when it doesn't work even before they checked out themselve what things a really happening.
