TXT documents have many rows, need VB in sequence from the first line of every five seconds to read a row, each row have eight fields, such as: 1,2,3,4,5,6,7,8, in each of the eight fields respectively read into eight textbox, until the end of the reading,

CodePudding user response:

It isn't difficult at all,

"Every 5 seconds to read 1 row", it is ok to use the Timer control,
Specific to read the file, there are many kinds of schemes to implement,

Your "eight fields in a row," that you have to clear the data format!
If not, who knows what kind of, you need to do to "is divided into eight!"

To put the data into a TextBox, use the control array and can be done For loop;
Even the independent control, control pattern, but also 8, hard to write article 8 assignment statements directly also just as well...

CodePudding user response:

Have not learned VB mainly, but the graduation design to use, eight all strings

CodePudding user response:

Why every 5 seconds as opposed to every 0.05 seconds

 Option Explicit 
Dim flag As Boolean 

Private Sub Command1_Click () 
Dim strLine As String, strCol () As String 
Dim As Long, I n the As Long 

Timer1. Interval=5000 
Timer1. Enabled=True 

Label1="Reading... "

Open "c: \ test \ test1. TXT" For Input As # 1 
Do Until EOF (1) 
The Line Input # 1, strLine 
StrCol=Split (strLine, ", ") 

N=UBound (strCol) 

For I=0 To 7 
If I & lt;=n Then 
Text1 (I)=strCol (I) 
The Else 
Text1 (I)="" 
End the If 
Text1 (I). Refresh 
Next I 

Do Until flag 
DoEvents 
Loop 

Flag=False 
Loop 
Close # 1 

Timer1. Enabled=False 

Label1="Finished" 

End Sub 

Private Sub Timer1_Timer () 
Flag=True 
End Sub

refer to the second floor qq_42230566 response:

mainly have not learned VB, but should use graduation design, 8 are all string

CodePudding user response:

Note: to join the time control

CodePudding user response:

The upstairs, you tried your code?

CodePudding user response:

I'm afraid you even "time control" (" the Timer control "!) What the "operation mode" (I mean in the "application"),
Haven't understand...
