To disable minimize and close button in VB6

[damini_dd]

I have created one form in VB which after validating proper user id and password allows internet access to the user. So if user is authorised to log in, form creates object of IE. But I've hide taskbar and also have disabled alt+tab key. so I want to keep atleast one window of IT to be open. So for that I want to disable minimize key and close button. So plz help me.

Thanks

Do you want to do this to IE or your VB form?

[BodwadUK]

Take the border off the form

Property is "Borderstyle" to 0

You can use an api to always keep a check on if the program is lost. Remember Alt+F4 can close a program

[damini_dd]

IE object doesn't have Border style property. My screen has only two windows, one is my form using which i've created IE object and my form which shows time left for log out. But if IE window gets closed before logout time, there is no other way to open new IE window as i've made all windows disable. but i don't want user to minimize IE window which I've created using program.

hack i don't know about 'damini' but i sure want to know how to do that to your vb form

you know some of these questions never crossed your mind until somebody else asks

[BodwadUK]

Why not embed an IE control into a form of yours and control it directly

[damini_dd]

I want to do that in VB form

[timeshifter]

that's what Bodwad just said. Put the browser control on the form, and size it the same as the form. Then set the form's BorderStyle property to 0-No borders. That will prevent people from closing the form.

To Clarify more (just in case):

Right CLick your toolbar add components > Microsoft Internet Control

now draw the new control on your form.. it is IE so it will act the same

[BodwadUK]

Sorry I should have elaborated. Be warned though, always distribute you application completely. We found the ActiveX for IE changed unexpectadly and caused trouble on old machines unless it was included in the root path of the application

Here's any easy way to do it.

Set the ControlBox property to 'False,' but that will also get rid of the Minimize and Maximize buttons. This works great if all you're doing is prompting the user with a popup form to enter supplemental information that gets used as input on an underlying form (like you might do with field level input validation) and you want to control how the user enters and exits the popup.

Your exit strategy is to have "Okay" and "Cancel" command buttons on the form. The user can then enter the requested data or not. But you control how they exit the form.

That's very funny, really! If I was coding VB6 nine years ago I would have been happy to help. But I ran into this problem just today and searched the Internet for a solution since I couldn't find one here (unless I missed it).

I searched this forum high and low for a simple solution that didn't rely on large blocks of code, Windows APIs, or DLLs. As operating systems change, those solutions tend to break and are difficult to fix. Not finding an acceptable solution here, I turned to the Internet and searched until I found something that fit my style and programming philosophy.

I thought it was important to share a more modern approach to this old problem. Therefore, I decided to post my implementation on this forum for the benefit of other newbies like myself, as rare as we may be at this point in time.

If we're talking about a VB6 form, I almost always try to do this with the BorderStyle, MinButton, MaxButton, and ControlBox properties. Things just work out cleaner that way. However, it can be done with API calls during runtime. The Min and Max buttons won't be removed, but they will be disabled.

Here's a little app with a Class that shows you a pretty nice way to get it done with API calls. (To Navion, just more "stuff" out of that junk drawer.)

xForms.zip

EDIT: Took unused DLL reference out of the VBP project.

I've got another version that subclasses the form and is able to control it much more, but I'll wait on someone to ask for one of the functions it has before posting it.

DLL is missing.

Hummmm you say ???

I'll check this up.

[Elroy]

gibra,

I'm not sure what you mean. Are you saying that you try and run the little project I gave you and you're getting a DLL missing error? If that's the cases, you've got some serious problems. The only DLL I use is user32.dll, and that's a VERY core part of the Windows Operating System. (There is a reference to kernel32.dll, but it's never called, and that's also a VERY core part of Windows.)

Maybe you thought I was going to include a DLL with my project. No no, not at all. This is the source code to show you how to do what the thread starter requested, "To disable minimize and close button in VB6". No DLL necessary. In fact, it's against VBForums' policy to attach compiled code.

I hope this helps,
Elroy

Yes.

If that's the cases, you've got some serious problems.

Sorry for you: I'm not problem, YOUR project has problem:

Reference=*\G{F3781BA0-FAAA-11D1-8B3E-DCAA556D18B8}#1.0#0#..\..\..\..\VB Etc\VB, Database, & HTML Projects2\xForms\gwsubcls.dll#gwSubcls subclassing component

Check your zip, please.

[Elroy]

Ahhh, so sorry. That's a reference that shouldn't be in there. It's not used. You can just edit the VBP file and delete that line, but I'll repost.

[Elroy]

Again, sorry about that. It's all fixed up now. Just go back to post #14 and re-download it. It's all totally standard (no subclassing) VB6 stuff now.

Enjoy
Elroy

I'm totally with you there. It's cleaner and more reliable in the long term. No moving parts to track and/or maintain.

Where do I get the gwsubcls.dll?

Seems to be required for this to work:
Private WithEvents subfrm As SubCls

[SamOscarBrown]

???? Did you download and run Elroy's project? No need for any DLL. Where do you see: "Private WithEvents subfrm As SubCLs"?

[clintc]

I must have downloaded an older copy.
I removed the "Private WithEvents subfrm As SubCLs" and reference and now it works.
Thank you!
