I am trying to see find out if a user has been inactive for a certain amount of time by mouse and keyboard events. I want to be able to find this from windows not my form. I am lost as to where to start. I came across this "GetLastInputInfo Function" but am not sure if that is right and/or how to use it.
View 18 RepliesI'm trying to make a program that takes user input and sets it to a time value.[code]..
I'm getting an invalid cast error. Does anyone have any hints on how to format the user input as a time value?
I would like to capture a start and end time in format hh:mm.Instantly I thought a datetimepicker would be the most suitable component (see code below)[code]Now I'm unable to find a datetimepicker solution to allow settings of intervals like in the numericupdown control and unable to even set a mindate/maxdate in time format. Does anyone have a solution for these requests? I then thought about using a numericupdown control to capture hh:mm time but I could not find a way of doing this in ONE control rather than two whichwould involve code to ensure only valid hours/min values could be selected i.e. 0 - 23 and 00-59 and other date to string conversion/validation.For such a commonly recorded element I'm surprised to find little in the way of solutions other than third party controls.Does anyone have ideas for a way forward for a control to capture time as hh:mm with interval controls for hours and minutes?

View 24 RepliesI'm currently in VB class at my highschool and we just got chapter 6.1 to read on this online textbook that we follow. Anyway, we are doing loops now and the problem reads "Write a program to request positive numbers one at a time from the user in an input dialog box. The user should be instructed to enter -1 after all the positive numbers have been supplied. At that time, the program should display the sum of the numbers." So far I know this much
[Code]...
Now I know this isn't right But I can't find out how I'd pull out the numbers the user entered to get the sum of them and not include -1 because as it stands, when I hit ENTER with -1 the label just shows -1.
Bit stuck on this one, have seen alot about how to do it just cant seem to get it right. I want to have 2 text boxes with times in them.. at the moment i have them on click events then it just runs a Now for the time and fills the boxes from the system time. But then i want the 3rd box to find the elapsed time from the 2 times in the previous boxes but i just cant seem to figure it out

View 1 RepliesI have been trying to check if a user has input a specific time format into a textbox.For example
1- User enters time in hhmm format
2- Checks the input
3- If wrong, MessageBox.Show("Need hh:mm time format")
I have only used IF statement with IsNumeric to check for number input but was unsuccessful with various attempts I can think of for checking a time format as I need Option Strict On and have the following error: Option Strict On disallows implicit conversions from 'String' to 'Date'.Is there a way to like check if the hh:mm has the ":" separator too?
I am using Visual Basic 2008 and I have two text boxes so people can input information and I am trying to get it so it will run a code with user credentials. However the code is giving me an error saying that "Option Strict On disallows late binding."Here is my code so far:

I have an assignment that is supposed to accept user input of random numbers. The only part I'm struggling with is I'm supposed to make copies of the array after the user is done inputting the numbers. These copies has to be sized exactly to how many numbers the user input. Am I supposed to use a counting variable and if so how?
View 5 RepliesHow would you let the user of a program enter an unlimted amount of numbers ranging from 0-100, and then have the program tell the user the highest and lowest values from the data they entered?The user would enter the data in when they clicked a button, and the program would sort the data out when another button was clicked.
View 8 RepliesI am writing an app that uses a combo box to list file types for a user to select from. Because a complete list of all options is both impossible and wildly unwieldy, I am only providing about 10 common extensions. I want the user to be able to type in their own file extension if the one they need is not listed. the first item in the combo box is empty by default, but during testing when i type something in their to use as my selection, i get the exception "Object reference not set to an instance of an object." pointed at extensionComboBox.SelectedItem.ToString
View 7 Repliesive been steaming on this one for quite some time. Ive got a program that relies on remote control of the computer, and i need to be able to take a webcam image without the user having to press buttons etc. So far, ive gotten to the point where i can find my webcam, and with the help of a button, start a preview, then take the picture and save it as a jpeg.Problem is, when you press the button to start the preview, another dialog box shows up (not related to my code) prompting me to select a video source..Im confused kus it seems as though the list i find on form_load does nothing at all if when i press the button it prompts me with the same list.Well you can infer from this that i cannot use the btnstart_click(sender, e) on form_load because it opens a dialog that wont close until i press ok, and i already tried to sendkeys enter, it didnt work.anyone have any idea how i can either alter my code, or make new code to take a web cam image, and save it with no user input?

I have a program that allows a user to select a program to run at a certain time for a specific amount of time all choosen by the user. Everything works with the exception of if my program has launched the other program, my program become non-responsive. Meaning I am not able to look at that window again. Not that one really needs too, because when time is up my program closes the program it opened, then closes itself. I just want to be able to see my program when the other program is running. how to do this and perhaps drop me some links, that would be wonderful. This is what I have coded, but like I stated there are no code errors.

I'm a complete beginner to programming alone, let alone VB.net. What I need to do is encrypt a block of text inputted by a user using a keyword that will also be inputted by the user. This is all to be done using ciphertext, so naturally the user would be informed the keyword can not have any repeating characters. I figure the English alphabet will be predefined in capitals and lowercase, then the keyword will be read character by character, removing those characters from the alphabet array and then appending them to the end of it (to create the new encrypted alphabet). How to read the keyword character by character, and then removing the corresponding letter from the alphabet. The best I can think is to check each character of the keyword against each character of the array which I'm sure is much more work than I need to do.
View 1 RepliesI have a form with multiple panels which hide/show as the user progresses through and inputs data. After they enter data in the first panel, I want a label in the next panel to be equal to one of their inputs. For example, in the first panel they enter their name in Textbox1. They hit next and it hides panel1 and shows panel2. Then I want Label1 in the next panel to be Textbox1 (their name).

View 2 RepliesI have a program that pulls orders from the database and prints packing slips and labels for the warehouse. There are 2 reports that print out every time and the are potentially 7 others that could print for each order. all of the reports will use the same basic information and just present it in different ways (i.e. label, packing slip, international paperwork, etc). the program we are currently using was written in a rush and I know is not efficient. I am pulling the same information several times for each run. I am trying to redo the program the correct way now. What I am asking input for is what do you think the best way to approach this is. I am currently using the System.Collections.DictionaryBase to store all of the information I need. I am thinking of creating more of those to store the information for each of the reports, but that still doesn't seem like the most efficient way to do it either.

How to generate code from user input. In Visual Studio 2008, Visual Basic. My script always begins with:
Code:
function Init(Quest)
Then from here a user would input a quest name, type and zone in a interface using windows forms.
Ex:
Code:
RegisterQuest(Quest, "Kill Zombies", "Heritage", "Firestorm")
end
This part a user would enter in his interface what would an NPC say if accepted.
[Code] .....
What I need is a few text boxs that a user can input "Kill Zombies" or whatever they like and when they push a generate button it will create a file with a .quest extension. All of the code remains the same except for the quotes that would be the user input from the interface. Basically everything in quotes can be changed by the user in an interface. I have created my own functions for when a user accepts, deny and complete a quest. The user just needs to input what should happen then click a generate button to throw it all together as a .quest file to be saved in his or her quest folder for the server to call on later.
I also have many other functions like:
AddQuestRewardFaction --- (Quest, Faction ID, Amount)
AddQuestRewardCoin --- (Quest, Copper, Silver, Gold, Plat)
AddQuestStepObtainItem --- (Quest, Step ID, Description, Quantity, Percentage, TaskGroupText, Item ID(s))
Etc
I would also like to have these available on the UI but wont generate unless a user checks a box to add them or there is a box already for them but wont step into the code unless the user enters something into the box.
I have an ASP.NET application with a SQL Server back end. I am storing all my dates in UTC format and doing the appropriate conversions to the local time zone of the browser viewing it. One of the pages asks for a start date and end date (no times).
I am taking the start date and setting the time to 00:00:00 hours (midnight) and I'm taking the End time and adding a time of 23:59:59, so that the date range covers the whole day. Now what I'm trying to do is do a SQL query to do a search for records in this date range. The problem is, the data in SQL is in UTC time and the user is typing their dates and times in their local date and times. My quickest solution was to convert the date and time to UTC, then search the records. However, by doing this, I am to believe ASP.NET converts the given time and date to UTC based on the server time zone. How can I convert a date and time to UTC time based on the time zone of the user?

I cannot figure out how to incorporate the number of days into the input box then get it to loop and count the number of times the User inputs in the number of days. Then I have to incorporate it into the equation to get the total distance D = MPH * Hours. What I have right now wil not count up the number of days and locks up after I input one number and will not add anything to the listbox. Because I also have to make sure that they cant add nonnumaric values and the number of hours per day cannot exceed 20. I have put things in and taken them out but it has been 2 days and I am lost now
iam currently working on my uni project and i have encountered a problem with valadation section.My system displays a message telling the user to input any fields that they have missed out on, listing the name of the field. However as these IF functions are in order the user must input the data in the order of how it is in the code. for example if the "consweight" is inputed and the calculate button is pressed, it thinks that all valadation above it has occured, when those fields are still empty.
