The problem of reading text on the interface in VC programming into the cache

cstring str;

getdlgitem(idc_edit1)->getwindowtext(str);

You can also use getdlgitemtext

The method is pretty much the same as the setdlgitemtext() you use.

It's this "it's cstatic, it can be like this:

cstring str;

cstatic *)getdlgitem(idc_static))-getwindowtext(str, 255);

cedit *)getdlgitem(idc_edit))-setwindowtext(str);

IDC static is the ID of the Yes control, IDC Edit is the ID of the box control, and 255 is the maximum number of characters.

With getwindowtext you can.

Alternatively, you can associate a variable with this text box, and then you can use the updatedata method to interact with the variable and the control.

lpstr lpmemory = (lpstr)localalloc(lhnd, 1000*sizeof(..

length);

.memcpy(a, lpmemory, 1000 * sizeof(..

Recycle LPMetym

lpmemory should be set to an appropriate value, not necessarily 1000*sizeof(..

You can't do this.,CformView generates a dialog box at the time of initialization (that is, according to this idd when it is just generated).,So even if you change it later, you can't use it.,And there's no way to change this (according to my knowledge and experience) because you have to specify this idd when generating your window.,And there's no function to change this idd later.,It's estimated that you will get an error if you change it.。 Hehe, if you want to achieve this effect of yours (I don't know exactly what effect you want, I understand that it is all dialog types but the content above is different - that is, there are different button text boxes or something), you can put a property page on the formview dialog and use the property page (you can control the display of that dialog box by using labels) to achieve it. This is because each property page can hold one dialog box.

If you have to use menu control, you can also call the property page object through the menu response to control the display of that property page, and there is a stupid way (and relatively simple), which is to generate an independent dialog box on the formview to cover the formview, haha, it's stupid, hehe, I guess it's useful to you, give points, haha!!

You can use ps to convert other formats into bmp format, and then which core is loaded, you can set a flag bit, bool flag;

When the flag is true, a ** is displayed, and when the left mouse button is clicked, the wm lbutton response is onbutton().

flag=true；

if(flag)

hbitmap hbmp,hnewbmp,holdbmp;

bitmap mp;

hbmp=loadbitmap(id);

hdcbmp=createcompatiabledc(hdc);

holdbmp=selectobject(hdcbmp,hbmp);

bitblt(hdcbmp,,,srccopy);

selectobject(hdcbmp,holdbmp);

releasedc(hdcbmp);

Envy slow code. That's it.

VC2005 and later versions, with their own cimage class, can be used to travel mathematics and physics jpg and other formats of the figure stuffy antifibrillation tablets.

Include the header file and you can use it.

vc6, just create your own library.

It is necessary to use the third-party graphic hand to serve the library. GDI does not support formats other than BMP. GDI+ can. However, I think it's much more convenient to use the cximage library.

Sow with srand(rand()).

Use rand() to get a random number.

If you want to display it in the cedit box, associate the widget with a variable such as m num (int).

button to trigger below.

srand(rand())

m_num=rand()%x+y;The range of random numbers is [y,x+y-1].

updatedata(false);

VC++ development experience and skills book, there are many examples in it, it is very useful.

Let's go up and have a look, mine is down there.

Do you want to answer this question? I don't quite understand what you're talking about, but what part of your dialog resource belongs to??? Can you make that clear??? Hehehe, haha!! Just send me an email, just hehe,

You want the three-dimensional effect of the buttons, right? To do this, you need 3 pictures of this button, one is in the normal state, one is what the mouse looks like after it is put on, and the last one is what it looks like when the mouse is clicked;

And the state of the mouse I think you should know.,Left-click to change the ** in the hit.,When the mouse moves to the button but doesn't press the second **,Other times it's the picture in the normal state;

It's the right thing to do, I'm a programmer at a game company myself, and that's what button stereo does.

This look at the book, it's not something that can be said simply, VC's.
