im trying to create a safe type programme on visual basic, which has a set combination button which when first clicked opens up a box to allow a password to be entered, once entered the safe is locked until you enter the password and push a button to try the key,
View 1 RepliesI am attempting to write a programme where a user can type in a 'string' into a textbox. A data dictionary will contain specific keywords relating to a specific classification, where an algorithm can detect whether any of the keywords occur in the 'string'. Here are the processes that need to occur:
1) A data dictionary, that contains keywords relating to specific classes eg. (IT Issues, Printer, Software, Password).
2) An algorithm needs to compare the words in the Data Dictionary to that of the 'string' to detect any matches.
3) A rule set to determine what classification the 'string' needs to be classed as.
i don't know what i said in this thread's topic is right or wrong.Since my perception about Delegates in .NET is that it is type safe .Delegate object will store the reference of only those functions whose signature matches with Delegate's signature .That i know from last 1 and a half year but never experimented .

View 1 Repliesis it possible to create a new "document" programmatically for any given application?
In other words:The user select a name from a list of installed applications.
The code starts the application and creates a new "document", specific for each application, with a passed name so the user can start to use the application.
I know how to start an application, but i need to see if it is possible to ask the open application to create and name a new "document". I need to know if there is a general code that can be used for any application to do the following
1) Open an application ( any, like words, excel, photoshop, visual studio2008 etc)
2) Force the application to create a new file specific for that application
3) Give a name to that file
4) The user starts to put data in it
I need to create a function which have either 1 parameter with a string as data type or 2 parameters with double as data type.Something like the substring method.
View 2 RepliesWhen I test run my programme (F5) it automatically saves files in a folder that is within the test project.I'd like to create a folder that is created when the programme is first installed (My Documents or in within the programme folder). How do I do this? I also want to give it a specific name instead of a name being given to it automatically. I know how to create a folder and save files in it during the test runs when I press F5 (If directory.exists etc etc etc) but that is during the runtime - how do I make a folder already available that is created during installtion.

View 5 RepliesI've just finished the coding for latest programme I'm making for a buses company, now the coding is fine. But the actual design of the forms is quiet tacky and amateur looking.The object here is to try and make my application look as professional as possible, I've noticed that on Vista, whenever you let's say transfer a file or load up something, they always have that really cool graphic right at the top of something moving, or something really cool happening.
I heard that there's a pack somewhere that you can download of vista designs for loading, file transfer etc, but I don't actually know where to find it.Does anybody here know?, or how they work?, or that just animated GIF files, or are they actually coded into the forms?
I have been doing a webbrowser for a few days and i had come to some problems i can't solve... First: how can i programme the right click of the mouse, like when the user clicks a link the option open in new tab works and it doesn't open IE. Second: I had a favourite system that when the user saves the page the items in a combobox are saved in a txt file. But the problem is that the file saves just this "System.Windows.Forms.ComboBox+ObjectCollection " and not the link of the saved page...

I am using VB Express 2008, on Windows XP Pro. I have written a programme which tests another programme which compares prices and terms from several vendors. This Bid Tabulation programme, compares prices and terms of up to 10 Bidders and 500 line items in mixed currencies.The testing programme, initially, would not work and I discovered that I needed to introduce a delay in order for it to run the Bid Tabulation programme. So my initial code, using the delay, was:
[code]...
And the button was clicked, and the Bid Tabulation programme started and ran successfully, as long as the number of vendors was 5 and the number of line items was 5. when I tried to increase the number of vendors to 10, the programme failed.I then discovered that at the point of failure, when the particular ParentHWND=0, if I introduced:
[code]...
Does anyone know what I am doing wrong, or whether there is another way to assure that ParentHWND will not equal zero without using a time delay?
I am using MS Windows XP, and Visual Basic Express 2008 and I am trying to write a programme that will enter a lot of information into another programme that I have written for testing purposes. The programme that I am writing to has up to 500 line items, by 10 possible suppliers; as you can imagine testing this every time is too labour intensive.[code].....
This code correctly takes me through the various forms until it reaches the Input General Information Form, which opens with the top TextBox in focus. However the entry, "Escravos Gas to Liquids", is placed in the last TextBox.How do I make it enter in the first TextBox, which is in focus? From that point on how do I cycle through the remaining 10 TexBoxes to make each entry?

View 4 RepliesI am doing a Management Science project at Uni. I have to programme a carbon emission calculator using proxy values and some input variables.
Basically, 4 inputs: seize of ship in container capacity (categorized in 9 classes), distance, Fuel type used (2 types), speed (if known).
How can I match the input variables with the proxy data values? Lets say someone inputs 2300 as container ship seize, the programme needs to know which proxy value to use from all the different seize categories (as it could have been 5300 or 7450). A certain ship seize class has a number of proxies (atributes). For example power installed, design speed, av. container capacity. (Classes are ranges, i.e. from 1000 to 2000 containers = class 1, 2001-3000 = class 2 etc.)
The same principle applies with the other input variables except for distance. Speed only should be considered if it is known, otherwise the programme has to use proxy data as well.
In short, it is a calculator which, depending on some input variables, estimates carbon emissions based on proxy data. The problem I have: How do I let the programme know, if a certain ship category/speed is selected (inputted), which proxies the programme has to use. The rest is just a matter of adding/subtracting/multiplying/dividing the proxies and the input data to calculate the emissions.

View 5 RepliesI am looking to create a VB 2008 Express programme which converts a data stream from a picoscope muscle sensor into a power output board which controls a mechanism.In simple terms when the Muscle sensor reaches a value of 0.8 V or higher I want the programme to send a text file to the power output control programme, and likewise when the sensor is below 0.2 V I want the power to be zero.
So 0.8 V > = send text file (0O=100%)
0.2 V < = send text file (0O=0%)
so when muscles being senced move the device turns on and off.I think I am successfully getting the data stream from the Picoscope which is plugged in the usb. I am using codes and examples that the programming guide for the device provided.here is a quick snap shot of the code (ps2000 is the driver used for the device)
ps2000_open_unit()
ps2000_set_channel(ps2000_handle, 0, 0, 0, 1)
ps2000_run_streaming(ps2000_handle, 250, 1000, 0)[code].....
how to get the data to be displayed or how to tell the programme to do something with the data.The device also came with an example of how it can record data to an excel sheet if anyone needs the code to gain a better understanding.
This is not a problem, as my code works correctly, but a question of aesthetics. I have written a programme which compares the prices and terms of up to 10 Bidders and 500 line items in mixed currencies. For this small section of the programme, I paraphrased a jmcilhinney CodeBank example; his looked neat, mine looks ugly.
