View 4 RepliesI have been reading through Atheists posts in regards to client-server and TCP client/server connection's. But how do i go about writing a program with 1 client and server where the client side creates a text file.Once the server sees there is a text file it connects and downloads it to itself or the client pushes the text file to the server.Once on the server i will read the text file and put its info into a sql db.
View 14 RepliesI need to create an application that creates Pascal's triangle the user would enter the number of rows, and using the formula (which i do not know... :/) would create the triangle. For example: the user enters 5 rows
triangle:
1
1 1
1 2 1
1 3 3 1
1 4 6 4 1
as you can see the numbers are created by adding the 2 numbers above it starting with 1 at the top
how can I add a user to a table in a mysql database without datagridview? [code]
View 6 RepliesI have a Car object that does a few things, but I need the program to create New Cars without having to write the code for every new one. Basically, the user checks some combination of Checkboxes and then pushes a button. And I need the program to create a New Car with a unique name for each combination of checked Checkboxes when the button is pushed.
For example, if Checkboxes 1,3,5 were all checked, it would create a New Car that had a different name than the New Car that is created when Checkboxes 1,2,3 are checked.
But I also need the program to be able to check when a New Car has already been assigned to some combination of checkboxes, so that it doesn't create a New Car every time that Checkbox 1,2,3 are checked and instead will use the Car that was already created.

View 6 RepliesI am using the following code to write and empty (dummy) file to take up the remaining space on a device.RemSpace is a Public Variable declared as Long I have a function that gets the remaining space on the device and stores in the RemSpace variable (in bytes). I have tested with a msgbox to display the result of RemSpace, and it comes back correct (not 0).

View 5 RepliesI have been thinking about creating an event calendar. I thought through the idea of how i would attempt it, but only came up with one idea; Text files, a folder for each year, and a folder for each month.. when the user creates a new event a text file gets created in: e.g. \2010\Jan\12.txt and if another event is on that same day, the text is added into the same text file. But this leaves lost hopes for my other ideas, since it will get very complicated. Like yearly events, monthly events etc.
View 6 RepliesHi, I'm working on a program that reads text entered into a textbox and creates a list of items by separating entries by commas. Everything is working fine, except, because I am using an array to store the items in the list, I have a limited number of entries. This is only a problem because, as it is written currently, each comma counts as an individual entry. Therefore, users can enter ",,," for example, and it would use up 3 places in the array.
I'm looking for a way to check to make sure there is text after the comma before adding an entry. I've attempted to use the .substring command to check the character after, which works until it gets to the last character. Because there is no character after that, it will give an error.
Here is my code for extra clarity:
Public Class frmMain
Dim intCounter As Integer 'Stores the # of commas in the string
Dim Messages(49) As MessageProperties

I am working with a Vb.net 2005 application. On the application I have a Create table button which when clicked creates a table in Sql server with the code shown below;
Code: Private Sub BtnCrtTable_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles BtnCrtTable.Click
[Code]...
This is really a pre-defined table and the data is already specified to be inserted to the table. However, my primarily task is to read a flat file which has the data and consider the first line as the column to be column names.
Therefore, initially I created an open dialogue to browse for the text file and store the path such as E:Datafile est.txt, in a TextBox1 visible at run time. Now the task is to change the above "create table" to read the txt file (column names are on the first line) and then create the table in the database.
I want my program to be able to create a '.txt' file when it is run for the first time, with the date and time the program was accessed, and to be able to add new 'logs' of program history every time it is accessed. What i mean is that i want my program to be able to create a '.txt' file, and then fill in the dates and times when the program is opened.

I am trying to create a file association in my program, which requires me to create some keys in the registry. However, when I try to create the keys, I get a System.UnauthorizedAccessException.
I have tried searching for a solution, and the only thing I can find is various examples of passing a boolean value to request write access for the "OpenSubKey" method. My problem currently is not opening the key, it's creating it. I have tried several of the different overloads to no avail.
I am guessing that I will need to temporarily elevate the access of my app to create the registry key. What I don't want to do is permanently raise the access of my app just to accomodate this one, small function, which should only really be needed by the user one time in order to create the file association.
Here is my code in progress:
Private Sub chkSOPAssociation_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles chkSOPAssociation.Click
If chkSOPAssociation.Checked = True Then
[Code]....
I have a checkbox on my form. When the user clicks it, it sets the file association if the checkbox is checked, or else it deletes the association if the checkbox is unchecked.
I want to create a program in vb .net that let me know who is using a specific file? Because I often update an .exe file but if it's in use I can't overwrite it. So if I know who is using the .exe I can call him to tell him o close the app.
