LabWindows/CVI Idea Exchange

Starting with CVI2012 NI provides Win7 style popup menus to select files or a directory. Unfortunately, with the new functions is is not possible to select files from more than one directory, and it is also not possibly to select multiple directories. So one has to choose either to use the old-fashioned, outdated look and feel from the MultiFileSelectPopup function, or to use the new design but limited functionality... This choice is not a good one

I vote for a combination of the two - the look of the new and the features of the old functions

Hello,

the FileSelectPopup(Ex) provides the option to choose 'Select' or 'Load'... buttons with the benefit that the users choice of files can be limited to existing files only.

Unfortunately, the new MultiFileSelectPopupEx behaves differently, with the new function the user can always select new file even if it doesn't make sense in a specific context, hence the programmer has to take extra care for this scenario. Also, the response is different for "newfile.c" "existing1.c" "existing2.c" and "existing1.c" "existing2.c" "newfile.c". From a users perpective, however, this doesn't make much sense.

I understand that most of these restrictions result from Windows and thus can not be easily changed.

But may be it is possible to use a similar idea of different buttons (OK vs. Select) for the multifile popup, too, allowing the programmer to limit the user to select exisiting files only. OK would keep the current behavior, while Select would restrict the choice of files to existing files only.

Thanks!

I thought I'd submitted that in the past, but I can't find it.

I would like to programmatically do what the F11 button does in the user interface editor: change the style of a control into another one of a similar category, keeping whatever attributes are compatible. For instance a numeric into a thermometer, etc...

Currently ATTR_CTRL_STYLE is not settable, and I tried to write some way to transform a control into another with NewCtrl/DiscardCtrl but the main problem is that the control number changes, which complicates the rest of the program needlessly (you can't use constant #defines).

I was operating on Pop-ups,I felt need of feature like java.

In Java when we have display Message we can easily concatenate variable with message string by using '+' sign.

Ex.

    In LabWindows,when do message pop up,

   {

    int var = 3;

    MessagePopup("Message count","Message No : "+var);

    }

     such a feature should be there.otherwise we do some string operation then Display message like " Message No : 3".

    So it increases string operations and string operations gives problem in memory management.

So at least In API's such '+' sign for concatenation of string with variables should be available.

Even if it is C language supported.
