For code below that I wrote:

It just can check the file condition only once, that this is only the program first load.
If I suddenly remove the file, it can't show a message " File not Exist" or if I suddenly receive a file and place at the folder, it can't show me a message "File already Exist"

View 4 RepliesI need to create a program that checks to see if a certain process is running, but I need to check it at a predetermined interval, such as every 10 seconds. I also need it to relaunch the program if it disappears/crashes. I have no idea where to start, I'm assuming I'd have to use a timer and write a method that checks for this process and then another method to simply launch it.

View 5 RepliesFor my Visual BASIC class we were asked to create a project to compute your checking account balance.Included in the project should be three radio buttons (deposit,check, and service charge), one text box (the amount),and a read only text box which will show the new balance. The balance should be calculated by adding deposits and subtracting checks and service charges; Each of these must return an updated balance. If there is not enough money to cover a check,do not deduct the check amount, but charge a service charge of ten dollars. The problem I have continually run into is keeping a running balance without using do or for loops. Here is a copy of the code i have come up with which will display only what I enter into the amount text box and put it into the balance read only text box; it will not accumulate.
Code:
Private DepositTotalDecimal, CheckTotalDecimal, ServiceChargeTotalDecimal, BalanceDecimal, AmountDecimal As Decimal
Private DepositCountInteger, CheckCountInteger, ServiceChargeCountInteger As Integer

I'd like to make my app check for a running process, I know how to make it check for a running process by its name but not by its location.
It would be extremely helpful if someone could solve this issue for me.
I'm making a new program so I won't be able to post my code here yet.
But I wanted to ask you fine folk how I can check if a program is running for the first time.

Just start the program normally and when they click the menubar ask for the password they set in the first time
if it's a little iffy on my side but I just started this project and I've only made the GUI and I have no idea what so ever how to do this.
I am trying to create a small application that will tell me if a website is up and running. This application will monitor if the site goes down. The problem is that there are several websites sharing the same IP address, and I cannot use ping to monitor it for the same reason. I do not know what type of code can I use to query the availability of the website. I read about webRequest and webResponse but I do not know how to get the response information that will tell me if the site is up or down. The code should be able to tell if a site like "mundo.reporters.com is accessible. That is the only thing.information to point to a potential solution will be more than welcomed.
The server is hosting 8 websites that share the same ip address, and I need to constantly monitor if they are functional.
This is my
Private Sub Timer1_Timer()
Dim procs() As Process = Process.GetProcessesByName("samp-server")
If procs.Length > 0 Then

I have MDI Parent Form and i'm going load all form as MDI child. Here i'm going to give option to "Close All" toolstripbutton in top of MDI Parent to close All mdi child forms.
Now i would like to check that On click of Close All Toolstripbutton , i have to close all mdi child form but except those form is on process, example, I have opened/Loaded 5 MDI child forms within MDI Parent Form.
Child forms are ( just for example ) ,
1. Customer details Form
2. Item Details Form
3. Import Orders Form
4. Stock Details Form
5. Production Entry Form
Here 3.Import Orders form is importing from Excel with 5000 records and 4. Stock details form exporting to excel.
So now if i click "Close All" button then i have close only Idle form i.e 1,2 and 5 but i should not close 3 and 4 since its on some process.
So Is there any .NET option to check that form in process/idle or do I have to check manually by having any Flags ?
Well, its not text, but a number. I've currently got about 10 labels and right now I'm checking each one of them separately using if statements, but I've been told that there is an easier way using a For statement (I've never really got used to it...) to check all of them without having so many if statements... Currently I'm trying something like this (which, ofcourse, doesn't work and is completely wrong :X)
Dim i(10) As Integer
i(1) = label1.Text
i(2) = label2.Text

when trying to run a function in a separate thread, my reason for trying this is because since the application is only run on one thread, the GUI hangs when the function is called.[code]In this code, the Print screen Button is pressed and the function HookCallBack is called.The problem is that the function has variables that need to be passed and returned, and while searching, i found a website that had an answer for this, and it required the function to be put in a class, and then it could be run on a separate thread while still passing all the variables needed.url...But the code cannot be placed in a class without giving errors and it seems to me like i did something wrong. The code is meant to be used in a form and not a class.My question is, how would i go about running the HookCallBack Function in a Separate thread?

View 10 RepliesIs it possible to run a function or to execute a button just after the form was loaded? I mean to execute it just as the form_load subroutine has ended, so the form is already being displayed.
View 2 RepliesCurrently the process is in VBS, however this means there is no real interface.I attempted to get this into HTA, but this doesn't work to well due to known issues - the interface doesn't update with information until the end of the code (functions) are executed.So I thought I would create a VB program to do the work.Ideally, I would have a form load, and once loaded the functions (which map drives accordingly) will display the results on the screen.My code should be pretty sound - it is working - but it seems to be invoking BEFORE the form is displayed.I have tried various subroutines, such as Form1_Load, Form1_Activate, Form1_Shown, but all of these execute the code before the form has loaded and is displayed on the screen.As a test, I have
Private Sub Form1_Shown(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load

I have created an application using visual studio 2008. The application is to copy the data from one excel file and paste to another excel file. The problem happen when i try use the copy paste function at the same time in other excel file.(I have opened others excel file before the application start.) I'm noticed the value that i paste is not same from what i copy in the excel file.(the application is running behind and using copy paste function at the same time.) How to hold the value using vb.net when copy from excel for the application so that other copy paste function is not affect it?
View 2 RepliesIn my .NET porject, I have to run a lot of validation on 4/5 fields. This validation checks if certain fields have errors, for example: the name field is not allowed to have numbers or symbols. If all these checks are passed, I need to execute a SQL query to pull some data out of the database. I could have it with a lot of nested IFs, and run the function at the end once it passes them all, but this will translate into about 12 nested IFs, and it seems a really bulky way to do it. I have also thought about setting a boolean value after every check, and if the value is 1 then don't run the function, else do. But of course this gets overwritten by other checks that pass.

I have a form set up where I want to run the function PopulateGrid on it's Form_Load event. I have initialized the DB connection as follows:
Private Sub Main_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
LoadConfigFile()
cn = New OleDbConnection("Provider=Microsoft.Jet.OLEDB.4.0; Data Source=" & config("DatabasePath") & ";")
cn.Open()
End Sub
Now, I want to run the PopulateGrid function directly after I connect to the database as shown above. I'm confused as to how I'd use a database query in a module when the database is initialized in my main form. Would simple setting the variable cn to public work?
