I want to create a form that, when starting, will display in a ListBox the content of a txt file. I know the file is read because I can display the content in a MsgBox. Here's a snippet of what I tried so far:
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Dim filein As String = "MyProjects.txt"
Dim objReader As New System.IO.StreamReader(filein)
ListBox1.Text = objReader.ReadToEnd
objReader.Close()
End Sub
When I debug my app, ListBox1 is empty.
I have loaded the file, split the delimited text into to separate arrays. One array is for the' object name', the other for its corresponding text.The text is no issue. My issue is that the 'object name' would look something like "form1.label1, form1.label2..." This loads fine, but I can not figure out how to get the 'object name' to be used as an object.I dimensioned the array for 'object name' as an object, but this won't work:
objectname(i).text = "..."
Looking at the values of the 'object name' array, after each listing it says {string}I need this to work this way because the file is loaded with the idea that it could be in any order, longer or shorter then another, etcetera.
I'm trying to make a simple game, but i have a question.i have a minimum damage and maximum damage lbl boxes on 1 form and i have a button if clicked it opens a 2nd form with buttons that deal "damage" when clicked
1. Attack (a regular attack that would deal the damage from form 1)
2. another attack ( this deals damage from form1 + 8)
3. another attack ( deals 30% damage for 4 attacks [so 4 attacks that deals 30% damage each])
4. another attack ( this one is great. it deals damage of 2 times of minimum damage to maximum damage and a third label box lblAP (attack power) which each 2 points of attack power you have it adds 1 more damage.)
i can do that math i just have no clue how to bring the info from form 1 to form 2.
I am trying to do is fill out a form with certain info, put the info into an array, and write it to a listbox using loops, arrays, and maybe a function if I need one. This is for VB2010 and here is what I have so far... I think there are ways to make it shorter but I cannot figure it out.... maybe just brain dead from all the coffee I have been drinking!
I'm writing a program in VB.Net and loading the info into a SQL database. Debugging it works fine on my machine that I am programming it on, it connects to the database and runs through all the info perfectly. However trying to get it to run on another machine it will not connect to the database. I realize the reason for this is the connection string, it's looking specifically at the file directory for the database. How do I change this so that it will function on any machine. The program is only intended to run on one machine at a time and not over the internet.
It has the ability to recursively grab all .wmv and .mp3 files in any chosen folder, and add them to a playlist.When opening the playlist, my program adds all the songs to an array, then starts adding the songs to a listview, categorizing them by song, artist, album, and genre, using a dll to access the ID3v1 tags on the .mp3 file.It can successfully create playlists of thousands of songs at a somewhat okay speed, the problem is loading that into the categorized listview.It used around 75% of my friend's CPU while loading his 5k+ song playlist into the listview, and it never finished after loading it in for a couple minutes (it auto updates as it loads, because it is done in a new thread.) It never finished because his OS has a bug where, if the CPU usage is over 100% for more then a few mins, it BSOD's, but that's beside the point.
His CPU, by the way, is a quad core 2.33 GHZ processor.The listview loads thousands of songs by using a lot of CPU [low amount of RAM, less then 40MB 99% of the time], and it does it slowly. [code]I've already redone the sub once or twice to speed it up, and at the moment it's 2-3.,
I have 2 forms. When a user clicks something on form1, form2 pops up. After user is done with form2 and closes it (where the dataset is updated), I want form1 to "reload" the dataset to reflect changes made in form2.
In the frmPanelSchedule form's load event I am loading 84 labels, 84 comboboxes, 420 textboxes, and 84 buttons.
The form takes a long time to load.Is there a way to speed up the loading of the form?
Private Sub frmpanel1Schedule_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load ' create pole labels lblPole(1) = New Label With lblPole(1)

I'm making a database app. I've finish the search, add new, and add function. What I'm trying to do is to expand the functionality of the add new item function.
During Loading a form, I bind a datasource property of the DGV to the bindingsource, and then set the fillweight property of the DGV columns. But, after form being shown, earlier set properties are being reseted to default = 100.
The procedure is like: 1. TestForm.Show() 2. TestForm_Load(...) Hnadles MyBase.Load DGV.DataSource = bindingsource DGV.columns(0).fillweight = 80 DGV.columns(1).fillweight = 120 3. Me.close() (Closing the form which called TestForm.Show()
And now I have visible a TestForm with well binded datasouce seeing all the columns, but their fillweith property was beeing reseted...

I have an MDI Form that contains an MDI Child form. On this child form is a flexgrid. When the user double clicks on a row in the flexgrid this loads another MDI Child form. I have set the following properties on the second child form:
The problem is that if the first MDI child form is in a maximized state and the user double clicks on the flex grid, the second child form loads in a maximized state too! How can I stop this?

I want to use a form in vb.net 2010, so when I click on a button ,it must show me the info of a specific row in Exel and display info of that row in a text box.
Is there a way to turn off all visual updates to a .NET form while I am manipulating it? When my program first loads, for example, I set the tab control to the tab that was last open. The user can see the program switching tabs.
I have looked into SuspendLayout and ResumeLayout, but either I don't understand what they are doing, or I am not using them correctly, because they don't seem to have any effect. Someone told me that there used to be a way to turn off paint events in VB 6. Does this still exist in .NET?
I want to create a form that a user will enter information into. Once the user hits "Submit", the program will search through my db. I want the result to populate into a completely new form. I only need the info from one column in order to generate the entire record, but how do I carry the info retrieved from the search what the user selects into the new form in order to populate the new form.
I am having trouble passing my summary info from my main form to the summary form. Only thing I have been able to have it do is show me the OK button to exit the program which is essentially no progress
I have a database, and I am creating many forms that pull info from the db and write info to the db. I have a form that asks for a set of information. One of the box is a combobox that has a list of values. I have a button at the bottom of the form that will allow the user to enter a new value to the values that populate the combobox if the user does not see the value they need. This will obviously populate a new form to create the new value.
I want the information on the first form to not be lost when the user hits the button to enter a new value for the combobox, yet I also want the combobox to display the new value.
Is there a way to save the information from the form and repopulate the form with the info the user entered? If I reload the form undoubtedly the form will repopulate the combobox and my new value will be there, since I have it reading and pulling info from the db on loading the form.
I am working on multiple forms that once the pricing is added to a list box and everything is totaled in label's will allow the user to submit the form and it will take them to a "receipt page" I have tried multiple times to get it to display and it won't. This is what I have.
Function CalcSalesTax() As Decimal 'Calculate the sales tax Return decSubtotal * decTax_Rate End Function
How do I transfer info from one form in Access to another form in Access of similar fields, ie last name, first name, address, etc. without making the second form a subform? I have a command button on the initial form to send me to the second form, I just need to copy the info into that second form. This is what I have so for in the event procedure:
Private Sub Follow_up_Form_Click() On Error GoTo Err_Follow_up_Form_Click Dim stDocName As String
I am upgrading from VB6, using MSXML.XMLHTTP object. I believe I have gotten the .Net Webclient to send the form fields, and a response comes back from the site, but everything in frames. The VB6 code automatically had all of that data, how can I get that in .Net I know this is a Newbie question if you can point me to documentation,
I have just added a login form to my main form which just has a username textbox and a password textbox. What i basically want a user to be able to do is enter their username and password into these fields and then for the form to store the values there.
So if they enter their username and password, and then click OK on the login form, if they were to open up the login form their details would still be there?I want to be able to call on these values else where? How do i store the info in the username and password fields? And if they then closed the form and opened it up again would it still remember what username and password had been entered?
I've searched and searched for an answer to my question, but as of yet, have yet to find a solution to what I'm looking for. My background - 6 months out of College (Computer Studies)
Right now I'm working on a program that is going to be used to handle database information (Access 2007). On the main form the user can select 3 pieces of required info from drop down list boxes. Those are required. Then after that they are able to enter a first name and a second name. They then add that name to a list box below. They can add as many names as they want to a list box. Then from there they have the option to either just save the info, or if required (which will more then likely be the main option) print each person in the list their own certificate. I have designed a separate form laid out the way required for the certificate.
The trouble that I'm having at this time is that I am unable to make the printing process show all of the certs that are going to print in a print preview. I have been able to get it to only show one. The form is set to load where hidden = true.
I have a WebBrowser in a Windows Form, and I want to automatically fill out a login and password field, then send the data to the server to log me in. How can I do this in VB?
