VB looks for the number of 123 in the list and deletes all items named 123

on error resume next

dim icount as integerfor i = 0 to - 1

if = "123" then

trueicount = icount + 1

if icount = 2 then msgbox "123"

end if

next i

for i = 0 to - 1

if = true then

iend if

next i

All items that meet the criteria are selected before they are deleted.

lz can give it a try** and you can achieve your requirements.

dim xx1 as integer

xx2 = ""

for xx1 = - 1 to 0 step -1if = true then

xx2 = xx2 + " " +

xx1end if

next xx1

xx2 = xx2 + " " +

I guess your intention is not to let the written program run two instances, just add **.

private sub form load() to the top.

if = true then end

end sub

As a rough idea, the list is converted into a map collection such as:

with iterator iter =;

map map1=new hashmap();

while (

Circulate. iterator iter1 =;

while (

That's about it.

Then you can only compare them one by one with loops. Something like this to compare. i+1 cannot be greater than the length of the array. Otherwise, it crossed the line.

list a=new arraylist();Adopt.

This method generates a list with a name a, and then you can use the number of elements to get it, and then use n as the nth element, so that you can take out the elements in the list one by one, and after taking out the elements, compare the last two elements, you can use the method of writing an additional function or class to solve it.

It's good to go through the list once with the hashmap. If the value is in the hashmap, add it to a new list, and if not, add it to the hashmap.

First, it is converted to an array, then sorted (which requires rewriting the compareto method of the entity), and then the adjacent data is compared to the version.

This purpose is a bit strange, and your right to realize the idea doesn't feel very right. If you want to get duplicate data, why not save it in maps?

Add: Delete the object if it is not the same? Or do you delete the object if it's the same?

Create an object that you have.

bai will create the , and then du will override his zhi equals() method, specifically to compare each back of the object dao.

value,,After answering, iterate over this list,Iterate it out and use the object's eual method to compare whether the 2 brother objects are equal,Unequal remove() is OK。

Dear, remember to make the question clear when asking questions!

Note: If it is in the same folder, enter the file name directly. You can also use an absolute path, such as:

c:\123\"

.\"represents the upper two levels of folders, and so on.

For example, in the C: 123 folder and in the C: ABC folder, it is:

.\abc\"

If under the C: 123 456 folder, under the C: ABC folder, it is:

.\abc\"

And so on. In addition,"123,bat", 0, 0 and true after true are all run parameters, where the parameters in the 0 position can take values from 0 to 10, and the default value is 1 if you don't write it. The meanings of the other respective representatives are as follows:

0 Hides one window and activates another.

1 Activate and display the window. If the window is minimized or maximized, it is restored to its original size and position. The first time the window is displayed, the application should specify this flag.

2 Activate the window and display it as a minimized window.

3 Activate the window and display it as a maximized window.

4 Displays windows by recent window size and position. The active window remains active.

5 Activate the window and display it at its current size and position.

6 Minimize the specified window and activate the next top window in Z order.

7 Displays the window as a minimized window. The active window remains active.

8 Displays the window in its current state. The active window remains active.

9 Activate and display the window. If the window is minimized or maximized, it is restored to its original size and position. When restoring a minimized window, the application should specify this flag.

10 Set the display status based on the program status of the launched application.

The following parameter true means that the following command is executed after the execution is completed, and the default value is false (the next command will be executed without waiting for the execution to be completed). The advantage of this is that, for example, if you run a Win32 GUI program, it will wait for you to finish executing before proceeding to the next step, and batch processing can't do it.

run also has a return value, 0 indicates that the execution is successful, otherwise it is a failure. So, you can order.

returnvalue= "",,true

to determine whether the execution is successful, and then use the if statement to execute the conditional selection command.

Mark, ask 2 questions, first, I give the answer will the landlord adopt, second, is the above one json, if yes, please send me json, I'm too lazy to knock it myself.

AD should be chosen, -25 is definitely integer data.

Analysis: The decimal point is directly discharged, and the integer value range is -32768-32767. Therefore B can be discharged.

The answers are A and D. It is not with a decimal point, and it is not if it exceeds the range of -32768 +32767.
