View 3 Replieswondering if someone can help me some small issues I am having with building my first project.
1.I have comboboxes that allow users to enter their own choices in and then their choices are displayed into the gridview.
the problem I am having is this is allowing me to duplicate choices. for example:when I run debug to try my boxes, I can type in Johnathan into the combobox as many times as I want to and it adds is to the combobox list..so now I got 10 johnathans in my combo box.and then to make things worse, when I hit the button I made to send choices to display..it causes duplicated choices to show up in the display.What I figure is that it is easier for me to just prevent duplicates in combobox.
2.Lets say on one of 10 comboboxes I got...lets say someone skips the box and doesnt make a choice...my grid will then display the last choice made.. (man o man)for example:John chose in his boxes and is displayed on gridview: Combobox1 (john) Combo2 (5:00 PM) combo3 (waiting)now lets say I come up to the computer and in Combobox1(Dcurvez) Combo2( i skipped and didnt enter a choice) and Combobox3(In Progess)
The display will put Dcurvez....5:00 PM.....In Progress because I didnt make a choice in the time combobox..it put in the last choice (Johns) as 5:00 PM Can someone in very simple terms tell me how to fix this problem?? I am using visual studio 2008 and vb/vb.net as language this is not a webpage, btw. it is for in shop computer just.

View 20 RepliesI am trying my hand at making a simple poker hand analyzer in VB 2010 for a distance education intro to VB course at my school.My goal is to represent the cards in a table array. Rows are suits Clubs/Diamonds/Hearts/Spades and columns are values (A, 1, 2... K). However I have no clue how to design a Sub procedure that will recognize the hand the user inputs and add any possible results to a listbox (fourkind/threekind/pair/flush/straight/ace high straight). I don't understand how exactly I'm supposed to do this. My criteria isn't very strict. I can have a hand with more than one description, like a fullhouse + threekind + pair can all be used to describe one hand.
What I think I need to do is split the entered string to get 5 strings (each is a card). Then somehow find these in the table? I have no idea how to do this and I'm stumped... The instructions loosely call to look for a boolean value where cards(i,j) is set to 1 of the player is dealt card j in suit i. But I do not know how to achieve this.
As you can see my understanding on VB is extremely... basic (no pun intended). It's my first time ever learning a computer language, and I really regret taking this course via distance ed because the instructor and the TA absolutely refuse to communicate with the students. I am trying my best to practically self-teach with the thick text book.
I'm attempting to do a school project dealing with a simple web crawler. I have a form with a web browser control embedded that loads a web page will all the available courses. I have a text box and a button design for a user to search for a specific course by using the four letter department abbreviation. The page that I have loaded has all the department abbreviations as hyperlinks.is it possible to search the page using the four letter abbreviation specified by the user and if the search finds a corresponding hyperlink open it. Then I would use a loop to repeat the process of opening each class offered by that department and obtaining information such as course name, section number and so forth.
View 2 RepliesI would like to click next to go to another image in a picturebox but I only have one picture box setup to have the new letter displayed in it. I have 26 images to display and need to know how to setup a loop to go through each image? It seems simple but I cannot figure out how to get to the third image, it only goes to the second image and stops. I also need to know how to setup the back button to display the prior image in a picture box.

View 3 RepliesI'm sorry if this is in the wrong forum or has already been asked, but I'm having a problem creating what should be a relatively simple code for an Excel Project. Essentially, the code is supposed to check if a certain column has Y in it and then copy that entire row onto another sheet and then move on to check the rest of the original sheet. This version of the code seems to do everything but actually populate the cells with the information. Every other attempt I've made has ended with "Application-Based or Object Based Errors". I've worked on this code for a few days now and I just can't seem to get it right. What am I doing wrong?
Here's the code:
Sub PopulateNewSheet()
i = 2
Do While Worksheets("Main List").Cells(i, 2).Value <> 0

So i'm creating a simple application as an example that is to link to a Access 2007 database.
On my main form i have four listboxes that are correctly attached to the table, I have one for First Name, Last Name, Phone, and School. I added 3 records to the database in Access to see if I could display the records in the listboxes on the form. I found that it was very easy by setting the properties and I have no problem there. I also have a command button that loads a new form for the purpose of adding a record to the database.
Here is my main form (frmMain.vb)...
CODE:
And Here is the code for the form...
CODE:
What i'm looking for is when the user presses the Add button on the frmAddNew form then it needs to close and the new record is listed in the textboxes and saved to the database. Id also like to know all kinds of things i might be able to do with textboxes and databases because i'm trying to learn for a larger project where i'll need to keep track of hundreds of records.
I understand that this is a simple procedure, but i've been spending all night scouring tutorials and getting lost in the msdn library online, so maybe some human input will be better.

View 1 RepliesI have a combox with a bunch of choices already populated.
View 3 RepliesI have two combo boxes, and four buttons. When the user clicks "Add" on the first combo box, it adds a new item to the combo box with "New" and then lets the user rename that item to something else. That "new" item has to have an array of "answers" that go along with that item in the list. What I'm having trouble figuring out is assigning "answers" to the second combobox for each item in the first combobox and changing the second combobox when selecting an item in the first combobox.
EXAMPLE:
Item 1 - Combobox1
- Item 1 - Combobox2
- Item 2 - Combobox2

View 3 RepliesWe are looking to port our existing classic ASP application to .NET, but we're unsure of what language to use for the new app. I personally would 'prefer' C#, as I'm more familiar and comfortable with that languages way of doing things, but, the original code is VBScript, so it would possibly be easier to port to VB.NET ... One possible situation I fear would be that, because the code is so similar between the two variants of VB, that we might end up getting stuck on something that is not similar between the two, even though it looks like it would work. A shift to a wholly different language might avoid that kind of situation. Does anyone have any practical examples of this kind of situation? Insights to illuminate the issue with? Do the potential benefits of a complete paradigm shift outweigh the gains from a high degree of 'copy-and-paste-ability' ?
View 9 Repliesi'm trying to display a random messagebox that displays a message associated with a character. the character image displays and the user clicks a button to guess the character if it is correct, one of three messages should randomly appear that is associated with that character (there are 4 characters, so there are 12 possible messages total. 3 for each character) but as it stands now, the picture box on the form displays the character name so the user doesn't have to guess which button to push. i need to remove the name from beneath the picture so only the buttons have the name and the user is forced to guess and i don't have the messages randomly popping up. only a messabebox that says correct i added a message box in the code but i can't figure out how to randomly get the messages associated with the characters to appear?

I am currently programming in Visual Studio 2010 within VB.NET and am using DevExpress v10.2, specifically WinForms. In the DevExpress GridControl at runtime you can click on the right side of the column header and choose which values in the column you want to show. For example if your table contained:
Name1 Checked
Name2 Unchecked
Name3 Unchecked
Name4 Checked
Then if you click on the right side of the checkbox's header you can choose checked (or unchecked) and it would display only the data that is checked (or unchecked). In this case with checked you would have:
Name1 Checked
Name4 Checked
I was wondering if there was some way to override the names so instead of letting me choose checked or unchecked I could override it with 'owned' and 'rented' or 'active' and 'inactive' based on what the checkbox represents in that specific column.

I have a project that has several combo boxes on one form. The selection in a box can affect the possible choices in subsequent boxes. Right now I am using SelectedValueChange to fire the code that loads the choices in the later boxes. There are a number of possible events that I could use:SelectedIndexChangedLeaveLostFocusTextChangedI was wondering if someone could give me a rough idea what the differences are between these. Is there a 'best' evnet to use?Also, I find that most events work when the choice is made with a mouse click but if you click in the box and type in a value an event does not fire. How can I program for the case where the user enters a value by typing it in instead of choosing from the drop down list?
