I want a Timer that goes down lets say it has 12 Hours so there should be a Label looking like this:12:00:00 and then every Second the Time should go down. When the Time reaches 00:00:00 it should close and if the Program gets closed it should save the time that passed and if the Application opens again it should start counting down again there where it last stopped.

View 1 RepliesI've been working on an application recently, and have encountered a lot of setbacks. I'm considering switching the project to C#, but that would take a lot of time. Here's what I need to accomplish, but keep running into issues.
Here's what I'm trying to do: Automated, one-click downloading, with a status bar and estimated time remaining, etc. (~20mb downloads.) Unzipping/Extraction of files. So far, I haven't been able to smoothly achieve those with VB.Net (4.0) Has anyone? Or should I just switch to C#?
So I still working on a program that shows this. This is the code that I use two show the SA and PLATINUM text because on the file they are not the only characters on the line, like this:
set username=sa set password=platinum code to search only those two words.

Just a bit of an issue that we're trying to resolve here. Assuming We're implementing a business model as one dll and a data access layer as another dll. We want them to be de-coupled so we implement an interface for the data-access layer. Great, we could now swap out the data access layer and, as long as the new data access layer fulfils the interface we're good to go, right?
Except we're not. In the business model we need to insanciate the data access layer and, because you can't instanciate an interface, you have to instanciate the actual class. We need to know the name space and the class name.We're going to end up with a line of code somewhere in our business model that looks something like this:-
Dim test as iDataLayer
test = new namespace.DataLayer
Basically, we can declare test as an iDataLayer (the interface) but to instanciate it we need to refer to the actual class (DataLayer). So we haven't really removed the coupling. If we want to swap out the data layer for a different implementation with a possibly different class name or namespace then we need to ammend the code in the business model. We're trying to avoid that.
So far the best we can come up with is to use the activate instance method instead of the New keyword (Late Binding). Because that takes a string we could hold the namespace and classname in a config file or similar, so swapping out one component wouldn't invalidate the others, you'd just need to update the config. That's just our home-spun solution though and I can't help feeling there are betters ways out there.
I'm creating a program and i want it to secretly save when the user clicks on save.
In other words, i have made it so that it saves twice. Once for the user to read (like a fancy copy) and another that the program uses to open up the form.
Currently when pushed, 2 save dialog boxes come up after each other. I don't want this to happen. I want 1 to come up (the user friendly, fancy version) which is the easy part, but i also want the other 1 to save automatically and secretly without asking the user to set the destination.

View 2 RepliesI'm writing a report scheduler that is somewhat of a clone to the backupexec scheduler and the layout can be seen in post #10 here: [URL]..It works great and saves/edits/deletes records just fine, but now i need to compare those records one at a time in a windows service that i'm writing in order to trigger automated report creation and emailing - i already have the report and i already have the code for the emailing, i'm just looking for the most efficient way to loop through the table (that i've pulled in to a dataset) and compare its records with the current date and time - if true, the event fires.
[Code]...
1stSun, 2ndSun etc are bit fields, time is a datetime, and the remainder are varchar. My service checks the database every thirty seconds.The english version of what i'm trying to do is "Connect to the database, grab the entire table (it will always only have 5-6 entries max, so i felt 30 second sweeps was okay), and If today is the 1st Sunday of the month, and it is currently 11:00:00 a.m. (could be any day or time, this is just an example) - loop through the dataset to identify if any records match the time field or greater - if they do, fire the report

I have two datagrids, one show Item purchase and the other Usage. I have total the QtyUsed column which I place the total on the 1st row as 11, I would like it to show 8 and show the reminder on the next row and calculate the QtyonHand. Below is the code I've tried and in work but I, think I need to kind of loop to drop to the next row. I had to place the number 1 for i to get the second row, but there may be many more rows. Not sure this is clear.

View 2 RepliesI'm trying to create a version of the game Spill and Spell. I'm having problems with a click event for Labels that is supposed to exchange the .Text value stored from the previous mouse click with the current .Text value on the new Label clicked. The labels are initialized and stored in an array on the form load.
What's happening is that the values are remaining persistent to the label being clicked.
Desired Results (example):
User clicks on lblDice1 (sender), tempLetter is set to mouseLetter.CurrentLetter, mouseLetter.CurrentLetter is set to lblDice1.Text (sender.text), lblDice1.Text is set to tempLetter. (this part works)
User clicks on lblDice2 (sender), tempLetter is set to mouseLetter.CurrentLetter (s/b initial .Text value from lblDice1 above), mouseLetter.CurrentLetter is set to lblDice2.Text (sender.text), lblDice2.Text is set to tempLetter.
What's Happening:
The tempLetter and CurrentLetter values are remaining persistent to the Label being clicked on. Ie: lblDice1 click will only display the original text associated. If I click Dice1 then Dice2 and then Dice1 again, the original Dice1 text is displayed (same for Dice2).
This is a lot easier to see. All of the controls with the exception of a button ("btnStart") are defined in the code below. Click the Start button to show values in the DiceLabels grid.
The area that's the problem is Public Sub DiceLabel_Click
(this is a work in progress...)

View 1 RepliesI've got lots of textboxes bound to a Dataset. When I make changes to a textbox with the mouse/keyboard the rowstate becomes changed - and when I do the .EndEdit and update the row it goes to the DB.
I've got some textboxes that get changed in code. When this happens the rowstate remains UNCHANGED. Updates to the DB never occur.If the textbox is changed in code and I also change another textbox in the UI then both changes make it to the DB.
I've verified that the "in-code" changed field in the dataset is actually changed - but the ROWSTATE is still printing as UNCHANGED.Here I'm showing that field 29 has changed to "blank" - but the RowState still is UNCHANGED. Why would changes to the .Text property of a bound control does programatically not change the row state?
Seems a google for this does uncover issues like this - but nothing that's helped me fix it so far - here's one link I can't make sense of[URL]..

I have two tables < student > and <class> . In vb2008 i make the connection to the database, display the data in both tables, edit existing data. The problem is that when i try to insert new rows to both tables there is a problem when i try to save both tables at the same time. The save button is in the studentBindingNavigator. I connect to the db through the Add New Data Source. The message i get is Can not insert or change a record beause it requires a relevant record in table student. Does anyone know anything about it?The two tables are related to each other.
