I have a windows form in VB.NET. In that I create two Comboboxes dynamically during runtime. Lets name them CB_A and CB_B. Now when these are created, CB_A is populated by calling the handler which is created while creating the control.I want to populate CB_B which will depend on the value selected in CB_A. e.g. The first value in CB_A will populate one set of values in CB_B while the second will populate another set and so on...The approach which I tried was get the name of the CB_A and then deduce the name of CB_B, but it does not recognise as it says it cannot change from string to objec(combobox).
I am creating an add-in for Microsoft Word, I want to create a drop down menu that will be populated from another file, is there a way to dynamically populate the menu?
I am trying to figure out how to dynamically populate a listview with data from a file, except I only want specific lines and columns from that file. I have code right now that works to populate the listview from the file, but it writes the whole file and I only want specific lines and columns. Here is the code I currently have to populate the listview when the form loads:
I am creating an electronic display board using Visual Studio 2005, this will be an application using VB and not web based.What I am trying to do is use labels dynamicly and populate them from a dataset, Now there is a lot of labels on this board and to be honest the perfect solution would be to use a Data Grid View, unfortuantly I have to fit the information into a Custom Graphic that was created, hence the reason for labels.So obliviously I dont want to have to name each label and specify its information, for example:
Code: Public Class Form1 Dim NPB As Button Dim x As Integer
[code]....
As you can see, when I open a program from my menu, a new button will be created with text similar to this, "C:Program ". The button it self will not do anything. How can I create the method at the same time the button it is for is created? Also how can I change the text do that it gives me, for example, CCleaner.exe instead of the whole target path?
I can usually find the answers to most of my questions via the Google Gods, but not this time.I have a form that has a TabPageControl and on that page a collection of labels and text boxes via a usercontrol.
On the form I have a button that allows the user to create a new tabpage, when the code adds a new page, it automatically adds the UserControl collection. I can't get my head around how to access the objects on the newly created tabpage.
What I need to be able todo is take the index of the tabpage that has focus and translate that against the UerContol name, but I havn't a clue how to do it!
I am adding a grid of buttons to a form at run-time, and all of then use the same Handler.My question is : Is there any way I canadd the TextBox at run-time ?I know how to but without it on the form, the IDE isn't very happy about the "MyClick" Sub - TextBox1 is not declared......
' some logic here to make nice rows and Columns of buttons ' with different .Text and .Name Me.Controls.Add(btn)
I need to pull from an access database to populate a combobox. Then from there I need to have a second combo box populated depending on the selection in the first box. My thought of an example would be a website that is setup for selecting car make, modle,year...can that be done in VB?
I have asked this question before but didn't get any help. I am going to try to rephrase it a bit.
I have 5 input boxes; let's call them chck1, chck2, chck3, chck4, and chck5.Each input box has an associated checkbox, let's call them chckbox1, chckbox2, chckbox3, chckbox4, chckbox5. These are in a section called '*Step 3****
THe spec is that if you enter a number into one of the input boxes and check the associated checkbox in Step 3, the number gets populated into the corresponding box in step 4.
For instance, if i check a checkbox called chckbox1 and enter a number into chck1 in step3, that number gets populated into chck_amt in step 4 as long as the checkbox next to the inputbox in step3 is checked.
If a number is entered in any of the boxes in step 3 but the associated checkbox is not checked, the number doesn't get populated into the corresponding box in step4.The issue that I have so far is that if I check a box FIRST before entering a number, the corresponding box in step4 gets populated.
If, however, I enter a number into a box in step3 BEFORE checking the associated checkbox, that number does NOT get populated into the corresponding box in step4.Does anyone know how to ensure that whether a number is entered first in step3 or a box is checked first, as long a box is checked, that number needs to get populated into the corresponding box in step4.
I have tested the code for the DataSet and DataAdaptor and both work fine, and as test was able to place the MaxRows variable into one of the text boxes on my form so I know thats all ok. But I am now trying to use the function below to copy the 1st cell of each row into a combo box to populate the options and comes up with a null exception error but cant get my head around it.
I'm working on a project for personal use to make my life as an IT administrator a little bit easier. (Yea right)So basically, i'm creating a windows application with a form. On this form, it has a button, and a listview.When they click this button, it will load all "Windows XP run commands" into the list view. I also, have a on-click event to capture a click on certain lines in which it will automatically open said run command, or shortcut.
Here is an example of what I am working with so far. (It populates correctly, and the clicking event works like a charm. However, i'm just looking for a better way to clean this code up, or maybe, a better way to go about everything).Once done, I will populate this to the codebank if there isn't another similar thing out there.
On to the code:This is what I have for the form_load event
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load With ListView1 .View = View.Details 'Changes the view to "detailed" view .LabelEdit = True 'Allow user to edit text
I have my mysql query selected fields (item_code, item_name, item quantity, item_selltype, item_selldetail) but some of these fields are variants.
Dim sqlConn As String = ("SELECT item_code, item_name, item_quantity, item_selltype, item_selldetail FROM qa_items") Dim objDataAdapter As New MySqlDataAdapter(sqlConn, objConn)
I have created a sub that I am using over and over again. However, I am not able to get the values from the database. Screen shots and code attached. I need a second pair of eyes, can't seem to figure out what is wrong.
Form Load vb 'Populate the drop down lists PopulateDropDownListFromDB(cboReferrerType, "ReferrerType", "ReferrerName")
I select first value from a combobox1 but combobox2 was not populated corresponding to value selected from first one. Again I select same value now combobox was populated
the information displays in the datarepeater correctly when loading the form, but i can not get new data to be displayed, (when saved to the database) no matter what i try. I think it is just beyond me.here is the code for which i import the initial data into the datarepeater:
Function test() Dim bsStaff As New BindingSource Dim dtStaff As New DataTable()
I have a Report I created with Visual Studio's VB.Net ( I guess this makes my report embedded), which I can select a date range like starting and ending date but the drop-down listbox for the Name is empty and I have to type a name into it to work. I need to be able to choose the name because I won't know who is on the list.
I have a parent table called users which stores all the user info with a prime key field called ID. Now in the child table which has a seperate foreign key associated with the ID field in the parent table.
What I would like to do is be able to populate the foreign key once once the user uploads data into the child table with the user ID it has.
So far I have created the associated foreign key with ID field in the user table and also programmly through data-relation related the table but now sure on how to get the value from the relation.
The foreign key in the child table is called 'U_ID' as shown in the snipet velow.
I don't have access to VB.NET right now so I can't test this value:Dim lst As New List(Of String)(cookieValue.Split("$"c))i got this from another question , but was wondering if A. The list will populate correctly and B. What does the c represent?
Trying to populate a Dataagrid in Visual Basic Express (5), datagrid never populates Below is the code I am using, I get the recordset records and use RsCheck to validata there are 91 records, and can loop through data, but can not get the Recordset to bind with the datagrid.
I have created a connection string, and i am populating a dropdownlist with an ID from a sql database.I want to be able to click on a ID from the dropdownlist and run a query to populate a gridview with data. I have made the dropdownlist autopostback = Enabled. I am not getting an error.
Here is my code:
Protected Sub DropDownList1_SelectedIndexChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles ddlContracts.SelectedIndexChanged Dim ds As New DataSet
Since there doesn't seem to be any way to load old VB6 (ActiveReports) reports in .Net, I need to recreate dozens of reports in .Net. I'd like to do this in the least painful way possible.In VB6, the original authors simply did something like this for every report:
GetAllUsers() returns an SQL string which selects a bunch of fields; those fields are then used in the report.Now:How can I do something similar in .Net (either using the built-in Crystal Reports, or the built-in "Microsoft Reporting Technology")?I can't get "Database Expert" to recognize globalConnectionObject (an ADODB.Connection object); and if I fill a dataset and do
report.SetDataSource(dataSet)
It tells me "The report has no tables."How do I populate a Crystal Reports report!? (the connection string/data location is not known at compile time)
I am new to Visual Basic and I'm trying to make a simple combo box that automatically populates from dataset. The table is from BaseMaterial with the column Material.
