How to make a program wait till a shell command finishes? For example:[code]In this example the line "Finished" is first written and only after then the shell function starts. How to start the shell function first, and only when it has been finished write the line "Finished"?
View 6 RepliesI am trying to delay the execution of the send key command. In VB script, it was relatively easy:
obj.sendkeys "{enter}"
wscript.sleep 1000
obj.sendkeys "{tab} {tab}"
When I do it via VB express, it is clumping the code together. For example
Threading.Thread.Sleep(5000)
SendKeys.Send("enter was entered ")
Threading.Thread.Sleep(5000)
SendKeys.Send("double tab was input ")
Instead of pausing for 5 seconds, typing the keys then pausing for another 5 seconds, it pauses for 10 seconds and then immediately types the input. I tested this on notepad.
How do I replicate the sleep feature in VB script into VB? There appears not to be a sleep feature in VB Express 2010
I know that time delays have been covered before around almost everywhere. however a method that forgoes forcing the GUI to become temporarily non-responsive, is all but a myth, or at least to my findings. i have the need for a GUI program to delay before the next command, however using the current method, detailed following, it causes the desired effect however it dose make it much less polished as when you click anything else on the GUI it goes un-responsive for the directed time. [Code] make a sub called say Tdelay( milseconds as integer) and have it run a loop as many times as the milseconds variable indicates and each time making the thread delay for 1 milsecond and then update the GUI/form in some way, then re-loop.
View 7 RepliesI have an application in which I save transactions. So I have a datagridview populated with records and i test for changes in the datatable when saving.then i loop through the changed rows and save in the following order:I have a command that saves a wage.then a command that saves interest.I use this to save as a transactiondate:
acccmd.Parameters.AddWithValue("@TransactionDate", tdate.Date + Date.Now.TimeOfDay)
then the other command :
intcmd.Parameters.AddWithValue("@TransactionDate", tdate.Date + Date.Now.TimeOfDay)
but sometimes the code is executing the two commands on the exact same time. Now I have a query that displays a running total and on order for the running total to work properly no two transactions should have the same datetime for a particular person.how can I add a delay between the two commands to ensure the datetimes are saved differently?
I have a simple dos command, I use to stop a java service which I am trying to execute within VB.NET, however it doesn't seem to stop my service.My DOS command which works is as follows:

i need a command to delay my code for 5 seconds. [code] But this command freezes my application while it pauses, and while its frozen, the user cant move the window or use the application's interface at all..So do you know of any better delay/pause commands or methods?

View 1 RepliesI have a client application that has been in use on about 14 workstations for nearly a year now. on the admin side the old app works correctly but the new one comes up with an error stating a column (Job_ID auto increment primary key) in the database does not exist when inserting a new job record yet it still adds the job to the database. all information is correct. The estimation side does not come up with this error and all computers in both departments run the same exact application installed from the same disk. all issues seem to be related to the jobs table only. But the same workstations with the column not existing error on admin side have a different setup on the network and will not allow a desktop icon to be created by the new application or manually.

I was having problems updating information in my SQL database using my vb.net application, but recently I found the solution. However now I have run into another problem which is shown in the code below:
Private Sub cmdupdate_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles cmdupdate.Click
Dim conn As New MySqlConnection
Dim myCommand As New MySqlCommand
'#######
conn.ConnectionString = "server=" & frmLogin.txtserver.Text & ";" _
& "user id=" & frmLogin.txtusername.Text & ";" _
[Code] .....
The exception message is:
Fatal error encountered during command execution.
I don't know if this is simply a syntax error that can be fixed easily, or something to do with my database configuration.
I am checking to see if a textbox contains a number, or is null. If it is non numeric or null a message box appears asking the user to input the proper value. When the user clicks OK on the msgbox the program will continue to execute the code. I want it to stop executing the code and revert back to its default state as it would be if you just opened the program. What is the command for doing this so I can add to the if statement?
Dim numCheckV as boolean
numCheckV = IsNumeric(Vinput)
If numCheckV = False OrElse TextBox1.Text = "" Then
MsgBox("Please enter voltage!")
End If
My intentions are to add command line switching. I am trying to see if i could run my application in varoius ways i.e.
App.exe -S - Start the application in XX Mode
app.exe -T30 - Start application with 30 second delay
and that kinda switching.
First let me say that I am not sure whether or not this should go in this section or the API section, and if it needs to be moved I apologize. My issue is fairly straight forward, but for some reason I cannot get it to work.

I am using the following code to run defrag and to analyze if the C: drive requires defragmentation:
Dim analyze As Process = System.Diagnostics.Process.Start("C:WindowsSystem32defrag.exe", "C: /a /h /u /v")
This process runs through analyzing, runs it in normal mode & prints the progress to the command window.
My problem is that as soon as the process is complete the command window closes. I need it to stay open so that I can read the results.
I am trying to send a command to the external command line (cmd.exe) from the Windows form application that I'm writing in VB.NET (using VS2008).

View 3 RepliesI am using a CheckedListBox that is populated with Filenames (full path, i.e. C:TestTest.jpg)When I have the files that I want in the CheckedListBox I wish to click a Start Button which will process the list one at a time using an exe program that runs on the Command Line. There are arguments that need to pass to the command line as well as the file location in order for the program to process.I currently have it working but the issue is the loop finishes quickly and it is left up to the CMD.exe to finish the process. What I would like is for the LOOP to wait until each file completes processing before passing the command for the next file in the CheckedListBox.There some reasons I wish for it to work this way.
1) I would like to have a button that can Pause/Restart the Loop.
2) I would like to have a button that can Stop the Loop so the whole process can end.
3) I would like to have the Loop remove each file one by one from the CheckedListBox after it has been processed.
4) I would like to display a Message once all the files have been processed.
5) And if it were possible I would like to report the status either by text or a progress bar showing where it is at in the process.
6) And the ability to add some error handling if possible.
Since the Loop finishes so quickly as it just passes the command to the command line using the & as a seperator it is the command line that is handling the rest of the process. Because of this there is not control over it in the GUI.The code I am using allows the Command Line text to display in the Form so it won't open up a seperate window to run CMD.exe. This is the desired affect as I would like everything to appear to run from within the Form itself.

User need to select their prefferable data to show in report. What i did is i have a clear command first to delete the temporary table. The temporary table is basically a table to stored user selection parameter data. After the clear command, i have
a insert command to insert user selection data into the temporary table. What happened now is when i run the program exe, first run of the report is work fined, but not the second and the following times of execution. It will return null or blank report. The weird thing is when i execute it from development environment, it seem like the report is able to pick up user selection parameter and run the report for the first times and the subsequent execution.
i have seen this in many codes, just not sure where to start and how to call the command. what i'm talking about is having code as such (this is for save file dialog):
