About the input preset format problem of textbox, ask for ideas to solve it!

My suggestion is to create 3 textboxes side by side, separated by labels, and set the text value of labels to ', which is also convenient to deal with minutes and seconds.

Agree with the first floor.,Textbox will report an error if you enter special characters.。

Select the Chinese box - fill in the effect - texture (there are several in the PPT can be selected by yourself) If you are not satisfied, you can - other textures (use the texture you want to use).

for (var i = 1; i <= 100; i++)string s = "textbox", i);

textbox box = , true) as textbox;

is saved in textbox1..textbox100.

Name, regular, write a loop.

Hope this article can help you.

Array controls. Another idea is to traverse the controls (which is more conventional):

1. When we create a new slide, "Click here to add a title" will be displayed in the area by default.

2. If you want to delete the text box, we must first select the Chinese box, click the border of the text box to select the text box, and hold down the Ctrl key to select multiple text boxes.

3. After selecting the Chinese box, right-click the text box will pop up the function menu, choose to click "Cut" to clear, or press the delete key on the keyboard to delete directly.

4. In this way, the text box is deleted, leaving only a blank space.

Select the text to clear the format in the Chinese box, cut, and then right-click in the text box, there should be a "paste unformatted text", select it.

Select the text you want to clear the formatting, open the menu --> Clear --> formatting, or you can clear the formatting.

I've done this typography before. The most important thing is to help the school arrange the school magazine. I have also inserted ** in the text box. The horizontal row can be formatted. Vertical rows are not allowed. Hope I'm not mistaken. Hehe.

The first thing you need to do is determine whether the keyboard is typing numbers, letters, or calculated symbols.

Then, if it's a number, just append it as text. Then the conversion type will be counted.

Operators are treated specially, and other characters are simply ignored.

Set the text box content dynamically.
