Is there a way to delay the start of a text file? I am using this to call the TXT file after clicking a button: (opens txt file)
Process.Start("text.txt")I was wondering if there was a command to delay the TXT file from opening for a number of seconds?I use this to delay the Splash Screen: (delayed 5 seconds)
Threading.Thread.Sleep(5000)Is there something similar for TXT files??

View 2 RepliesI am puzzled by a delay in my data appearing (sql sever) when I open my program. (this can be around 5 to 6 seconds). If I open it a second time it appears instantly, have I done something wrong, or not done something. I have connect to a MS access database that connection is instant always.

when the program tries to opens an excel file, it always throws me an error "Office has detected a problem with this file. Editing may hard your computer" and my program crushes.......The problem appears on the SECOND line, on DIM wb...blahblah.. i went to the office and unclicked the "protected view" checkboxes.. but it still throws me those errors. my guess is that the office i have in the computer is not the same as the one that my program uses to open excel files (i mean, i loaded/imported some excel.dll files in the program so i guess that will be the one) But how do i make the program not care if the excel file is "potentially dangerous"?

I would like to be able to have my users open an Excel file and include their add-ins they have installed and usually show up when Excel normally starts. Using this code, Excel opens with no add-ins visible:
vb.net Dim excel As Microsoft.Office.Interop.Excel.Application
Dim wb As Microsoft.Office.Interop.Excel.Workbook
Try excel = New Microsoft.Office.Interop.Excel.Application
wb = excel.Workbooks.Open(filelocation & "checks.xls")
excel.Visible = True

Is there a property to allow add-ins when opening an Excel file?
I have created a picturebox in a form that I want to click on and then it would send me to a excel file that I already have created. I don't know if it is even possible. Do I need to use a button instead?, or am I just way off all together.
View 2 RepliesI 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.

Due to use postmessage tow times, I want add a delay (50) between tow postmessage(), and my timer interval is 1000.
Private Sub Timer2_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Timer2.Tick
If CheckBox10.CheckState = CheckState.Checked Then
st = Int(Val(TextBox17.Text) * 10)

and I konw Thread.Sleep(50) is not good, but how to use timer stop here.
In my program I have a tab control with 4 tab pages. In the second tab page there is a lot of controls (about 50! includes buttons, labels, combo boxes, textboxes, option boxes). When user opens the program and want to navigate to tabpage 2 there is about 2-3 second delay showing tabpage. This problem only occur the first time, after that it just shows the page fine. I am not sure what is causing this lag but the program seems buggy and slow to user.
View 2 Repliesto some server via an UdpClient. However, I need to make sure that all commands send are separated by a 1 second delay. If there is no delay, two commands send within this 1 second timespan will not be received both; only the first or the second command will get through.he commands are sent in a background thread at the moment, because it might take some time before the command is sent. I keep looping until the command has been sent, like this:
vb.net
Public Sub Send(command As String)
Dim bytes = Me.GetCommandBytes(command)

I am currently in the process of writing a demonstrative program that will generate a string of 9 random numbers in a textbox. Now my basic knowledge of VB 2010 allows me to do this but my goal is to delay the generation of this number sequence until the my progress bar has progressed to the end. How can I insert a delay after my button activates my progress bar/timer without stopping all function and usability of the program all together. The basic wait function seems to lock everything up for the allotted time and then the number instantly generates and the progress bar begins.
View 8 RepliesI am currently creating a program to send keystokes to a program at certain intervals. I need the thread to delay between keystrokes, and i need to be able to have the user input the amount of delay from the GUI via textbox. I have it running perfect with Thread.Sleep(), but it just isn't consistent enough. How can I code it to be accurate to roughly 5ms up or down? thanks, and here is the code. This is in VB 2010 by the way.

After the 7th line I need a pause until a submit button pops up on the screen. The submit button is hidden until the getelementbyid.focus is run. I cant use webbrowser_documentcompleted because the submit only unhides itself, and I cant use Sleep() because that just stalls the whole block.

Having difficulty with the module below failing on line 21. It is telling me: The system cannot find the file specified. (Exception from HRESULT: 0x80070002) Basically what it is designed to do is look for a directory, if that exists then look for a file in that directory. If both = True then it should open the folder to browse the files. I believe the issue is with the "Program Files" being 2 words since the script runs using a root path, but I'm not sure how to format the path correctly to make it work?

View 9 RepliesI'm having a slight problem getting my program to load a save file when double clicking the save file.I'm using the Command$() to get the command line argument. I can open a save file by dragging it onto the exe. But not by double clicking the save file (after it's associated with the exe).I though dragging and dropping a file on a program and double clicking the file would open it in the same way, but I guess not.So in short how does file association work and how do I get the file path set to a var when the program loads.
