Hi,

I would like to have a NUMERIC editbox style, so the user could only enter numbers in an edit box. Rolling Eyes

I did some testing with a loop that checks if there are some non-numeric symbols in the editbox, and then deletes them, but this doesn't work quick enough.
Someone who would types very fast could still cause the application to hang Confused

Thanks,
Vic

hi vic,

have you had a look at the api's?...i know that an api can set for editboxes to have only a certain number of characters...may be there is one where only numeric characters are allowed

another thing you could do is instead of removing non-numeric entries just use a check using @numeric() and if it returns false then let the user know giving them a chance to fix up their entry

hi vic,

so much for my api idea...just had a quick look and found nothing...sorry!

Not exactly sure what you're doing here, but why can't
ya just check if the entry is numeric before processing it?

Cheers, Mac Smile

Maybe you should try this? Smile

VDSOBJ.DLL also supports mask edits where you can limit the edit to only accept numbers.

Hi Vic
You can just change the style of VDS Edit boxes as shown in the code below.

Wow CodeScript! Very Happy

Good job... How did you ever find out about those
parameters? Very Happy

Hi everyone
I just quickly pulled the constant from skit's post to show that it can be simply applied to VDS edit boxes.

I didn't bother to check win32 help or platform SDK for all constants (Thanks mindpower for that).
Does Win32 help give the value of these constants ? Atleast mine doesn't Confused

So I had written a API constants reference for the same to avoid searching header files for them.

I don't think he was talking about that CodeScript. He's just suggesting
to post these things in a way that allows others to be able to read and
maybe understand the code a and information a bit easier. I myself
still have hard time with the API's, and I've converted a few already,
but they were all the simple API's.

Your title with your avatar is more of a way for VDS World and users
like me to show our appreciation of all your help. It just happens that
you've been one of the most helpful with API's, hence, even I would
have referred to you as an API Guru.

you are very deserving of that title codescript Very Happy

Sorry Codescript,
I was not trying to deminish your work in anyway. You are a very good programmer and I am sure that everyone here would agree that you deserve the title that the admins of this forum has given you. I was just trying to say that we need to remember that not everyone on this board is at the same level and we need to be more mindful of this by posting and documenting our scripts better since the areas that VDS is moving into is pretty advanced.

You are correct the Help file does not have the values but if you have any Win32 C compiler you should be able to get any constant value from the header files. The header files are usually placed in the include directory under the main install directory of the C compiler. At least that is where I get them from. If you download LccWin32 or Borlands free C++ compilers you can get the header files. In the header files just search for the constant's name (ie...ES_NUMBER) and get it's value... In C/C++ a hexidecimal number is formated like so 0x2000. The 0x tells C/C++ that this should be treated as a hex string. Constants in C/C++ are usually written as so
#define ES_NUMBER 0x2000

The line above is a pre-compiler directive and is not the only way to write a constant in C you can also define a contant like so and give it a data type.

const DWORD ES_NUMBER = 0x2000;

But you usually will not find a constant written like this in a header file.

Also most programmers in C and other langauges capitalize constants so that you can tell the difference between a constant and a regular variable when you read the code.
Also there are 1,000's of constants just for the Win32 API so I doubt that it would be very practical to put them all in a single program. I do however like your reference program that you wrote it's a nice starting place Wink

Keep up the awesome work your doing Codescript just know that I did not mean for it to sound like I was pointing directly at you... Many people on this forum do this. They post code with @Sendmsg but never tell people the name of the message that they are sending. It's hard to hunt these down when you don't know the name. The code you post here need not be perfect but should be reusable and readable by others. As for the title I reread my previous post and I do understand how you may feel but honestly I was not trying to single just you out. The admins here originally gave me that same title at the same time they gave it to you but I asked them to change that since I don't consider myself a guru at anything and I did not want the responsibility of it Very Happy

My comment was more meant just as a little razz than as a put down. Sorry for the sarcasim Embarassed
