I'm a novice, messing around with input boxes in VB 2010 Express. I know most programmers recommend not using input boxes except for the simplest things, but what I'm doing IS the simplest thing. Besides, I'm really just experimenting for the sake of learning.
I want a few input boxes to appear, one at a time. Let's say there are six input boxes in this project. The user can input anything he wants in each input box. After the user has entered text into the six input boxes, the program should write the text to a file. This is the part I'm having trouble with. [Code]
I haven't figured out if title.input is correct or not, or if I need something instead of commas in between each item. And the headers (i.e. the "First Name" stuff) needs to be added in there also, but I need to get the syntax of the code right first before getting to that.
For example, I clicked the Add Text box button, so it added 3 text boxes in the form (I used Dynamic text box so it can add multiple text box). When I input data to one of those 3 text boxes and then Save button has been clicked. It should checked whether the dynamic text boxes are empty or not. If there are empty text boxes, then saving data to db should not be continued and display a message telling the user that empty field(s) are invalid.
In the code below, it saves the data even if there are empty text boxes and I think because it is in the for loop, it checks the text boxes one by one and repeatedly displays the message box that I coded.
Here's the complete code:
Imports System.Data Imports System.Data.SqlClient Public Class Form3
Ok, as you can see I am totaly new with Visual Basic. I have learned all those loops, if&else statements, byval, byref and etc. But now, I want to create this kind of application. I have 3 textboxes. One will contain URL, second username, and last password. There is a listbox also and a button. I want when user add a values inside textboxes , that values go to listbox as one variable and then save those settings for user so when he start up application again there are saved variables inside listbox. I just dont know how to do that.
I had an Excel spreadsheet which I put in MS Access (database). I then took that database and used that as a source in VB to create a GUI for. In VB I have an input text box to search and pull of different fields. I created some queries for searches in from the text box. I have have a dataset view of the data which has the binding navigator (add, insert, save).
The problem I have is that when I hit the '+' for add to add information and then click the 'save' button in the binding Navigator, the information I put in does not save. I check this by exit out of the program run (debug to open the app) and then open it back up to search and/or check for the new information I put in. My overall goal is to create to publish the final code and use an a standalone program.
Also, as another option,(I would like to learn) Is there a way to map VB directly to an Excel file to have the user input information and save to the excel file.
Currently the reports are saved as a html file called report1.html, id like to make the user enter a name for the HTML file upon clicking submit.
A little stuck on how to make the filename for the HTML file save to a input entered by the user.
I currently have:
Try 'Open new HTML file to be written WriteHtml = New StreamWriter(Application.StartupPath & "ListHardware.html") If Not (WriteHtml Is Nothing) Then ' Is the File Open
Currently I am saving data from my applications by saving a text file via a stream reader as a string. I have come to a problem. In my current application, I have an array of the following structure:
how to permanently save to text files then re-open all of the information again using SFD and OFD. Now my teacher has come back at me and said that i need to be able to save the information from multiple text boxes and have the text in certain labels to also be saved into the one text file (the labels need to be done because it is a database and these labels are like the fields and the right text box needs to match the right label)
I am having trouble saving data from a VB Windows form to an Access database. I can retrieve the data ok but when I try to save back using the test code snippet below, I always get a Syntax error at the Update line no matter how I code the update. I have used the default Item 1, Item 2 column headers in the Acess database table.
Public Class Form1 Dim con As New OleDb.OleDbConnection Dim dbProvider As String
I am working on a project where I need to create dynamicly created text boxes (which works fine) and then save the values from those text boxes to a txt file.Essentially how the form works is their are a few static text boxes the user fills out and then presses a button to create a row of 7 other text boxes and they click the button for however many rows they need.Again this part work just fine, but its when I get to trying to save the values in those boxes that I run into trouble.I'm fairly new to vb.net and currently I only know how to save the static boxes using the WriteLine function, which unfortunetely doesn't work for the dynamic ones. [code]
I'm creating an application that works like a recipe box. it has a picture box that is in the design of an index card, and it has 3 text boxes. I am having extreme difficulty saving the text boxes with the picture. i am using a database so that the info can be filtered, by recipe name, course description (appetizer, side dish...etc).
i was just wondering if there was a way that i could compare data stored in a text file such as usernames and passwords with data input into text boxes in visual studio vb2008?

I am trying to save text written in an Richtextfield into a .txt file. The problem is that the vbCrLf's are not stored. The *.txt file is written in one line.
I was a professional software designer using VB6. Now that I've converted to VB2005 years later, use, with pages of unrelated information. With VB6 I could use Left$, Mid$, etc to parse keyboard input into a string. For example in the KeyPress event of a name box I could use
Case "A" To "Z" CFName$ = Left$(CFNameBox.Text, CFNameBox.SelStart) + Key$ + Mid$(CFNameBox.Text, CFNameBox.SelStart + CFNameBox.SelLength + 1)
When converting a program from VB6 to VB2005 the software changed the line to
When writing another program I used the VB.Left(), etc, but it gives me an error. So, the question is, what is the correct way to capture keyboard input from text boxes and construct strings?
I'm trying to validate input boxes for numeric value and range value. If I validate for either numeric value OR range value there is no error (for example, comment out one of the validation statements), but if both statements are present and I enter "a" I get an error "Conversion from string "a" to type 'Double' is not valid." Can anyone tell me what I'm doing wrong?
i am use vb 2003 windows app with access 2003 database i want this code to check for numeric input only in the last text box CompanyProdPriceTxBx.Text
this is my
Private Sub SaveCompanyProdbtn_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles SaveCompanyProdbtn.Click Dim rep As Integer If CompanyProdNameTxBx.Text = "" Then rep = MsgBox("Please Input Product Name", MsgBoxStyle.Critical)
I have an Access DB that lists customer details in a datagrid and in textboxes, when I use the edit button I can edit in the textboxes and when I click save the record is saved and shows in the datagrid. But when I exit the program I get "Syntax error in update command" Im not sure why because there are no errors in the error pane at the bottom
This is the code for save button Private Sub btnSave_Click(ByVal sender As Object, ByVal [Code] .....
I am having trouble saving a class to a file via Serialization. I am getting this error: Type 'System.Drawing.Graphics' in Assembly 'System.Drawing, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' is not marked as serializable.
I have changed the: Public Class cJigsaw to: <Serializable()> Public Class cJigsaw The next line in my class is: Public img As Bitmap
I tried adding the <Serializable()> attribute to this code, yet it has this error: Attribute 'SerializableAttribute' cannot be applied to 'img' because the attribute is not valid on this declaration type.
I could find on using the SaveFileAs Dialog control would get the part where the code should be to actually write the file to disk, and there would be this comment:
'insert code to write file here
or something similar. So anyway, I thought this might be of use to someone else in a similar situation. This is what I came up with to finally "save" a file with the SaveFileAs Dialog. In this situation, I wanted to save the current document of the WebBrowser1 control via the SaveFileAs Dialog when the user clicked the btnsave button...
Private Sub btnsave_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnsave.Click Dim saveFileDialog1 As New SaveFileDialog()
I basically have a program where people type in their username and password, and then once button1 is pressed the program takes you to a website and logs in for you. The whole point of this is to fast the process.
I've got a big database driven project...15 forms 50+ input boxes and im wondering how to do it effieciently. I've got code to connect to the mysql databse but i dont want to put it inside each form over and over for every form. How can i do it so that i only have to clal one method to connect to the db or leave the db connected constantly from the start of the app. here is the code that i got to put in every form -_-
I have a reset button created in my VB form, but don't know how to code it so that it will accomplish what I want. I want it to clear the form's text boxes so that new input can be entered. I could just code an end statement but this closes the form, and I want to keep it open to continue working with it.
I'm familiar with Visual C# and the try/catch for that but I cannot seem to figure out how to do the same thing in VB. Basically I can't figure out how to get the try/catch to work with text boxes and input from the user and whatnot.I've tried setting the textbox.text property = "" but that has no use, I've been trying to find something on Google about it but I cannot seem to find a single thing about textbox try/catch statements. Is it possible to do it with text boxes?
