Yes, a book is better. There is one called C++ for VB Programmers or something. The reason I asked about tutorials is because I was looking for the fastest way of helping my friend achieve his objective. That is, originally his boss envisaged a 3-day timescale for the VB application. So presumably with the C++ version he would be looking for the minimum time - no more than a a couple of weeks or so.

 That's one tall order!Maybe he could get one of the "learning in 24 hours" or "learning in 21 days" book. I haven't read those before, but if speed if what you need ......

Sorry, using these words in the same sentance with C++ does not compute 
Seriosuly though, I learned from books and asking questions like most VB programmers did. I also took a lot of heat from C++ folks

I am primarily a C++ developer myself but I'm aware of its shortcomings on the clarity front.

I'm writing an activex Control in VC++ to be deployed with VC++, VB and VBScript. The problem that i encouters is the following :
I writed a function in the Activex Code which takes as arguments a VARIANT FAR * which is a SAFEARRAY, in this function i should be able to read all variable Contents usibg SAFEARRAYs methods. With VC++, everything go allright. With VB, i just write the following code :
...
dim Lst as variant
redim Lst(2)
Lst(0) = 1
Lst(1) = 2
Result = MyActivex.Function1(Lst)
...
When debugging this program within the VC Activex Code, i notice that the the Lst parameter don't seems to have the good values, it contains another values. What should i do to pass an array in my Activex Function...
I need Your Help.

Hi Every body
I want to use VB object printer to print some informations exactly at a position (x, y) on paper.
I understand each printer has its own idea of what the printable area of the paper is.
Therefore i use Windows API to check left and top margin before sending data to printer.
I retrieve theses informations like this :
MarginLeft = GetDeviceCaps(Printer.hdc, PHYSICALOFFSETX)
MarginTop = GetDeviceCaps(Printer.hdc, PHYSICALOFFSETY)
With my own printer MarginLeft = 42 pixels ( 2.96666 mm ) idem for MarginTop
Now, i tried to print a dot (.) at position (0,0) like this, just to check:
Printer.CurrentX=0
Printer.CurrentY=0
Printer.print "."
On my paper (A4) i obtain this result with ruler : Left Margin = 2.9666 mm (~ 3 mm) BUT Top margin ~ 6 mm.
I dont understand why Top margin is 6 mm insted of 3
Is there any way to know where come this more 3 mm ?
Is there any way to set to force printer Unprintable area ?
Thanks in advance

Hi,
Can anyone help me on how to add a new button in the control box (i.e. next to the minimize, maximize and close buttons)
I've been searching the web and couldn't get help and I could really need help here.
Thanks
Gil

That is not a place were users will expect to find an extra button. (At least not me). So my advice is, don't do it even if you can.

Has anyone had any problems with the licensing.
All I am trying to do is license a server control, it should be easy but the control can't find the license everytime. Even the most basic LicFileLicenseProvider does not work.
The steps I take
1) Decorate the class [LicenseProvider(typeof...
2) add the LicenseMangager.Validate in the constructor
3) add the MyNamespace.MyClass.lic file
4) Compile it
5) Run it
Any help appreciated

In the project folder of the application that uses your control, you should have a licenses.licx file. This file must be included in the project and it must contain a line identifying your control. If this is not the case, this is the reason of your problem.
|

|

I have the licenses.licx file in the folder, forgot to mention that.
There is something wierd happening that I am missing, and cant see what it is. The controls are for web based applications and after tracing it through it seems to be in the getLicense method which is called from Validate. have tried the basic LicFileLicenseProvider in both C# and VBNet without success. I am using Runtime 1.1
Thnx

Is your licensed control in the GAC or in a normal directory?
Do you use your control in an application or a DLL (class library, wrapping control)?
|
|
|
|

Its not in the GAC. It is also a web control Library Assembly specifically for Internet apps. Inside of the library I have a standard web control and a second class inherited from the base control class which has no interface. Neither of the controls can be licensed.
I wrote a real basic test server control added licensing LicFileLicenseProvider, Validate, Dispose, [namespace].[class].lic, Compiled it. Created Host Web app, added the control and a license file in the bin same as the lic file in the component, added licenses.licx. Compiled and run,
Got the error "A license could not be found...", take out the validate method call control works fine in design and runtime.
Tried it in C# and VBNet both the same.
Thnx for your help

In your first message, you asked if anyone had any problems with the licensing. I have the following problem:
- I create a basic Windows Forms Control with a basic licensing (LicFileLicenseProvider). Let us call it Dummy.dll.
- If I use it in a windows application (DummyTest.exe), the licensing is working correctly
- If I wrap dummy in a another unlicensed control (DummyWrap.dll) and if I use DummyWrap in a windows application (DummyWrapTest.exe), the licensing does not work anymore (Notice that DummyWrap has a licenses.licx file since it uses Dummy.)
- Then if I add a licenses.licx file to DummyWrapTest itself, the licensing is working again. (I thought initially that the licenses.licx file was not necessary because DummyWrapTest is only using DummyWrap. It does not see Dummy.
- However there are cases where I cannot add the licenses.licx file to the application, for instance if this application is ASP.NET (I have not its source code!). I don't know what to do here to avoid the "license not found" message.

In your case I can see whay the licenses.licx is required. Even although you have wrapped the original control in a dummyshell it is probable that the dummyshell actualy creates an instance of the control anyway, which causes the licensing to kick in. The licensing is in the constructor.
The theory I have in my case is something to do with the path of the lic file being in a web. The License provider seems not to deal with this situation. Originally I wrote new license providers assuming that the implementation would be a walk in the park. Just to get it right I decided to do a quick test using the basic license provider and it didn't work!!. I am probable wasting time trying to get the basic license provider working and should just launch straight into implementing my custom provider.
Hope my comments helped in your case.
Thansk for your efforts anyway.

Hi,
I want to check whether a COM object or activeX, implements my new version of an interface or the old one, I know the GUID of my new interface, is there any way to check that using Visual Basic ?
Thanks in advance, greetings

Hi Daniel,
Thanks, but... what I have it's a GUID ( and I cannot import the TLB in order to have Interface...), it's possible to get the Interface from the GUID ?, or is there a TypeOf that works only with the GUID ?

Oh, I see... Well, VB6 do not have any feature like that. The way to go would be calling the QueryInterface method on the IUnknown (all COM interfaces have this method). Doing this in VB6 is cumbersome and involves some coding I would not show to children. The way to go would be coding this in a small C++ component.

Thanks for the Info,
Yes, I've seen some examples of that QueryInterface and I didn't believe it could be so difficult.... what a pity..., well let's hope that VBasic .net it's completly different that 6.0
