command inputdlg doesnnot work

Hello everyone,

Whenever i try to use the command inputdlg, the box appears but it is impossible to type any answer (there is no space for it).

i have been looking online and havent been able to find a solution to my problem

I hope one of you will have a solution on how to solve it

thank you in advance!

How are you using inputdlg? Attach the code or part of the code!

[Pauline]

the problem isnt coming from the code, i have tried it on other computers and it works perfectly, the problem seems to happen only on mine.

prompt={'quelle est la longueur du rectangle?','quelle est la largeur du rectangle?','quel est le nombre de noeuds sur la longueur du rectangle?','quel est le nombre de noeuds sur la largeur du rectangle?'};
title ='choix des donnees';

answer=inputdlg(prompt,title);

L=str2num(answer{1});
l=str2num(answer{2});
nbx=str2num(answer{3});
nby=str2num(answer{4});

Okay. It works fine on my computer as well. Resolution issues?

[Pauline]

hm when i open matlab, i always get a message telling me that "the program is going to change the color scheme to Windows 7 Basic" but i have always gotten it and if im not mistaken i think this command has worked before.

i was thinking that it was related to microsoft visual c++ but im not sure if its the case or even how to solve it if it is.

It sounds like you're running MATLAB via a VNC remote session or have connected your computer to an external projector. Are you doing either of those things?

[Pauline]

i havent done any of those things

i have downloaded cygwin recently to code in C/C++, could this program be in conflict with matlab ?

[Image Analyst]

I would not think so. I code in Visual Studio and there's never any such message. The only time I know of that Windows announces that is when Windows asks the video adapter to switch its spatial or color resolution. Is everything normal until you step on the line that says:

answer=inputdlg(prompt,title);

????

[Pauline]

yes, i just copied and pasted everything until this line and i dont get any error message.

[Image Analyst]

Why did you do that? Don't you know how to step through it with the debugger??? You don't need to debug by copying and pasting partial hunks of code to a new window and running it from there. Just click in the margin to set a break point and then type F5 or click the green run triangle. Then when it stops you can type F10 to step on code, or F11 to step into functions. That's the way you should do it. Watch this video: http://blogs.mathworks.com/videos/2012/07/03/debugging-in-matlab/ Then find out exactly what line of code makes the message appear.

What does this say if you type it in the command window:

which -all inputdlg

We need to make sure you didn't overwrite it with an m-file of your own with the same name.

[Pauline]

i tried what you said but i dont get any error message the commande inputdlg works in the sense that the box shows up , the only difference is that i cant type anything.

"What does this say if you type it in the command window:

which -all inputdlg"

C:\MATLAB701\toolbox\matlab\uitools\inputdlg.p C:\MATLAB701\toolbox\matlab\uitools\inputdlg.m % Shadowed

[Image Analyst]

That's a bit weird. I don't get the .p file listed when I do it.

So when you execute the inputdlg() function you are not getting the "the program is going to change the color scheme to Windows 7 Basic" message anymore?

You just can't type into the edit box? Maybe it's a focus issue. Are you sure you clicked in the edit field and the cursor is blinking in there?

[Pauline]

This message doesnt accure when i use the inputdlg function but when i open matlab

i doubt that this message is related to the problem im having with the inputdlg function knowing that i have always had this message appearing since i have matlab.

[Image Analyst]

So you're having two different problems then. I agree with Andreas - time to upgrade. One last thing you could try and that is to run your MATLAB in compatibility mode with XP (if you're using Windows 7 or later) to try to trick it into thinking it's running on XP which is the platform your old version of MATLAB was designed for.

It seems someone played with pcode.... Go to

C:\MATLAB701\toolbox\matlab\uitools\

and delete the file

inputdlg.p

Make sure

inputdlg.m

is there.

[Pauline]

i have never touched those pcode files

i just deleted it and tried my code again, i now get this error message

??? Previously accessible file "C:\MATLAB701\toolbox\matlab\uitools\inputdlg.p" is now inaccessible.

[Andreas Goser]

MATLAB 7.0.1 is pretty old and not supported on Windows 7, see page. I suggest to upgrade.
