How C # TabControl components display a form
Title, that is, when you click on an item in the MENUSTRIP1 component or TOOLSTRIP1 component, no longer jumps out of the form and all appear in TabControl, the TabPage page header name is also the name of an item in the component, and the form is designed first. You need to turn the content into a label form, and the new form is displayed each time a new form is added, such as when the form is closed with the last open form.

You can also use tab to separate fields. the rs2tab method is as follows:
Print rs2tab ($ rs, false );
Note: false indicates that the field name is not displayed.
The result is as follows:

I'm using a new version of TP 3.2.3. I have multiple methods in the same controller, I wrote a session in Method 1, why can't I read it in Method 2? To ask for explanation .....
The code is simple enough to write a controller that inherits controllers. Then there are 2 methods written in it, and the first method writes a session. The second method reads the session. Grammar is the session ("KKK", 999); The other is the direct echo session ("

Vs2005! However, if you use a key to encrypt text, numbers, and dates at the same time, it may be a bit of trouble! I just wrote a simple one and tested it! Still usable! Haha!
The Code is as follows:
Public class myencrytppassstring'Self-compiled simple encryption and decryption text string class'1. Keys: two. Define a key type: stringkeytype, which has two member types: Keya and keyb, and a public encryption string publicstr.'II. encryption:① Generate the final key and the validation string u

Another important purpose of typedef is to define machine-independent types. For example, you can define a floating point type called real. On the target machine, it can obtain the highest precision:
Typedef long double real;
On a machine that does not support long double, the typedef looks like the following:
Typedef double real;
In addition, on a machine that does not support double, the typedef looks like this:
Typedef float real;
:
'And IIF (select count (*) from validtablename) = x, 1, 0) % 00
Here"X"Is any value greater than 0. You can use the old method to determine the exact value of "X.
Step 4: Guess the Content Length
You can use the following statement to obtain"Attrib"Content Length of the first row of the column:
'And IIF (select top 1 Len (attrib) from validtablename) = x, 1, 0) % 00
You can use the following statement to guess"Attrib"The secon
