Look at the following two ways to implement: JS checkbox method One:Copy CodeThe code is as follows: function Checkall () {var code_values = document.all[' Code_value '); if (code_values.length) {for (Var i=0;iif (code_values.length) {for (Var i=0;icode_values[i].checked = false; }}else{code_values.checked = false;}} function Multipledelete () {var num = 0; var code_values = document.all[' Code_value ']; if (code_values.length) {for (Var i=0;iDocument.

1. As shown in the picture we make a test document which has Chinese and numbers, we are now going to delete the numbers inside
2. Pressing CTRL+H opens the Find Replacement dialog box, and then we enter [0-9] in the replacement of the open window.
3. We do not replace this without effect, we need to click on the lower left corner of the "more" button.
4. Then we open the interface will have a "use wildcard" now click it to select.
5. OK,
Create a dialog box-based MFC ApplicationProgramThe interface is as follows (default is used for all attributes ):
First, add a simple struct definition (before the class definition in the dialog box ):
Typedef struct _ tagnode {cstring name; int age;} node;
Add a member variable to the dialog box class:
PRIVATE:
Cptrlist m_list;
Then add several member functions for the dialog box class:
Void cdxdlg: insertnode (uint N) // insert n

Operation folder, delete all empty folders, Operation folder Delete
Operation folder to delete all empty folders. The first condition is to determine whether the file is empty.That is to say, the folder exists, and it is null if no file exists.

Teach you an invincible DELETE command, all rogue software and stubbornProgramCan be easily deleted, the method is very simple! Right-click the desktop-New-Text Document-(double-click the new text document on the desktop, copy and paste the following command) and write the following command: del/f/A/Q //? /% 1 RD/S/Q //? /% 1 file-save as "delete
Delete an unlimited category and delete all its subcategories at the same time. The copy code is as follows: $ actisset ($ _ GET [act])? Trim ($ _ GET [act]):; if ($ actdel) {$ sort_idisset ($ _ GET [id])? Intval ($ _ GET [id]): 0; $ sort_ids $ sor
The code is as follows:
$ Act = isset ($ _ GET ['AC'])? Trim ($ _ GET ['AC']): ";If ($ act = 'Del '){$ Sort_id =
private static Boolean Deletedir (File dir) { if (Dir.isdirectory ()) { String[] Children = dir.list ();Recursively delete subdirectories in a directory for (int i=0; i Boolean success = Deletedir (New File (dir, children[i])); if (!success) { return false; } } } The directory is now empty and can be deleted return Dir.delete ()
When I went to Q this evening, a previous student asked me online how to delete all subcategories under an unlimited category. I sorted out the code a little and sent it out, and put it in the php student Q A for future users to view it.
The code is as follows:
$ Act = isset ($ _ GET ['AC'])? Trim ($ _ GET ['AC']): ";If ($ act = 'Del '){$ Sort_id = isset ($ _ GET ['id'])? Intval ($ _ GET ['id']): '0 ';$
What is the reason for the recent explosion in the archive log, with the delete archivelog all seemingly unable to erase all archived logs?
