I've created a User-form in excel and I need help in the coding part of it.Currently I have coded the User form, as shown below:
Option Explicit
Private Sub cmdAdd_Click()
Dim ws As Worksheet
Dim r As Integer[code].....
The section which says 'Find first free row from A21' up to'Cells(r, 4).Value = Me.txtQty2.Value' (highlighted in bold) is where I need help. I currently have 3 combo-boxes called 'cboProduct, cboProduct2 andcboproduct3' and next to each one of them I have a textbox called 'txtQty1,txtQty2 and txtQty3'. I am trying to get the first combo-box to find the first free row starting from A21 and go to cell B21 and the first textbox to go to D21. For the second combo-box to find a free row from A21 and go to B22 if B21 is used and the same applies to the textbox , if D21 is used to go D22.This also applies for the third combo-box and text box. However my coding doesn't work.
I had been searching as to how I could create an array of controls dynamically, and after some searching found some helpful code as shown below [code]This way in the above code "structureComboBoxes" will have an array of comboBoxes (VB6.0 was way easy to get this crap done!! I guess its cleaner here)Now my next problem is How do i code for events of each of these combo boxes?
I think I have a simple program to create, but I just cannot find the syntax to complete it.Effectively, what I'm trying to do is search down a column where there are cells with numbers and cells that are blank. I want to search down the column and find where there are two or more cells that that have numbers, one after another. I want to add a row beneith the last number and then add up the total of that batch of numbers in that column were searching down. I know that I'll be using a loop to step down each cell in the column to check on the contents of the cell. Also I want the loop to go from the top of the colum to the last record since the list length will frequently change.
I use VB 2010, Office 2003 and Windows 7.All the office programs have worked fine on their own for several years, but when I try toconnect to Excel or Word via .net coding (That will work on other systems) the program fails because the
I'm learning how to use visual basic and come from a background in Java. In Java I use the swing class to build my interface and code all of it. Is there a way to do this with visual basic, or is the designer the only way to create an interface?

Im trying to code a button in my windows form that will function as "winkey+L". Ive tried send.keys but that doesn't see to accept the "winkey". [Code]
I'm looking forward to reading and adding more to the community here. I've created a text based rpg. Next semester we are learning Visual Basic. I'm on winter break and I would like to get a head start on my learning. I've been working on creating some forms and message boxes. What is throwing me off, is that I have a good feel for doing coding so that I get functionality the will produce effects in a console. Coding the forms is a bit confusing for me. Is this something that others have run into? Is their some good primers for VB? I don't have my text books yet.
I have been doing a lot of reading on this topic and most folks seem to agree that having Excel is required to use the COM Interop libraries. However they are never specific as to where that should be installed. Does it need to be installed on the machine I am developing on or does it need to be on every machine that I deploy to?
Edit: I should mention that this is desktop development/deployment targeted for all Windows machines.
With vb.net I would like to select 4 cells in Excel and then pass those cell values along with 1 button tag to a formula in Excel.I press a button with a month, say "May" as text. I want to grab a cell in Excel labeled "May1t" the value of which is the number of hours until may. This is the code I'm using.
xlsWB.Worksheets(2).Range(Month1 & "1t").Value I am able to set a variable with this as the value but,
I want to pass this cell (which will be updating as the time counts down) and 3 other similarly specified cells along with the button tag to an Excel formula.I have something like this:
Private Sub F_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles F.Click xlsWB.Worksheets(4).Range("B2").Formula = "=MyFunction()" xlsWB.Worksheets(1).Range(Month1 & "1t").Select() End Sub
The formula takes the parameters in the order: MyFunction(Cell,Tag,Cell,Cell,Cell).

Question is related to rather simple programs typically presenting some data in a few datagridviews, charts etc. And consisting typically of a main form and one or two settings forms.I'm trying to program in a layered structure, pulling every bit of code out of any form class, and having a seperate "program class" for any form that I make. Now.. So far you can't complain on that I guess, but how to do this in best coding practice? In the form class I make a member object of the program class, hence making the program class a child of the form. Now I'm able to create events in the child class, and have handler methods in the form, without writing delegate classes (it seems). Now, that is fine, as it enables me to update the form controls with such events happening in the program class. However, how do I send events the other direction, from the form (parent) to the program class (child)? I guess I don't have to use events, I could just use the member object to access public methods in the program class directly, with passing of parameters from the form controls.. however, is that good practice? Or should I use events also that direction, and how to make that work, do I need to introduce delegate classes
I am trying to code my pet age calculator form to allow user interface for the user to choose feline or canine, choosing the ok button will then invoke the frmCanine or frmFeline, can anyone work with me on this?
Public Class frmPetCalculator Private Sub rdoCanine_checkedChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles rdoCanine.CheckedChanged
I have a form that has 1 listbox and multiple textboxes. I need to write an array code to beable to select on an item in the listbox and then display different data into the multiple textboxes due to what is specifically chosen in the listbox. Im having a lot of trouble figuring this out.
My form contains lots and lots regular expression and other things in one button. whch when pressed takes some time to process.. so the form kind of gets stucked while the processing is bieng done.is there any coding for which it diables the entire form until the process is completed? like disabling the entire form and showing a text "please wait ... processing data" so user can not use other buttons or features at the same time or it might get crashed.
I am currently creating a tool that can manage local user accounts on Windows-PCs. I am using the functions described on
this MSDN page ; and after some struggling, I got most of them to work.
Unluckily, I haven't found a way to set the option "User must change password at next logon" while creating a new user account. I use the
NetUserAdd -Function to create the new user. I set the level to 1 and supply a
USER_INFO_1 -Structure . This structure accepts flags, and the flag UF_PASSWORD_EXPIRED seems to be exactly what I want - but when I set it, the user can log on without changing the password first...
I'm developing on Windows 7 Ultimate 64-Bit using Visual Studio 2010 Express.
Here's my code:
#Region "Constants" Public Const UF_PASSWORD_EXPIRED As Integer = &H800000 Public Const USER_PRIV_USER As Integer = 1
Say we have a DataGridView on the main form. I can chose to establish its properties by code or by selecting them in the Properties panel. Is there a difference between these two techniques, a loading time penalty in any of the cases especially?
I am a bit stuck with coding my save button and combobox.My entire form is ready, database is linked.All fields from DB are linked to their textboxes on the form.But i just ran into a big wall which i cant seem to break down.My save button, which is used to save the content from all the textboxes on the form to the access database refuses to work.The other this is, i want to use a combobox on my form to view the already saved entries in the access database.I think a combobox works for that, but i am not exactly sure how to pull that one off.
I'm creating a macro in excel using vb?What the macro is doing is checking if the row and column headers are same, and if it is then I want it to save the row header (the date in this case) AND the value (a number) into an array, and this is done in a for loop and goes on.... I dont know if I should use 2-D array or a 1-D array that stores 2 values....Not sure at all !Then after the outer most FOR LOOP is done, I want to print those values stored in the array.
Here is what I have so far, this works actually however i'm using 2 seperate arrays, one to store the row header (the date) and another array to store the value. But really I want to make it simpler, shorter and use only one array that stores both of these values as we go through the for loop and at the end of the for loop, all the values from beginning which are stored can be printed out.
Here is my code :
Sub Test () Dim sys_arr() As String ' declaring the array to store the values Dim sys_date_arr() As String 'declaring the array to store the dates
[code]....
This totally works but with 2 different arrays, all I want is just 1 single array (not sure if it is 2-dimensions or still stays as 1 dimension but with 2 different variables)... and then the array can store the date and variable correspondant to the date, and goes to the next row, and do same thing... So the output results should be like for eg :
2/12/2010 37 2/13/2010 41 2/14/2010 66 and so forth
Using VB.NET I created an excel sheet with list of items in dropdownlist.[code]But i can able to view the listbox upto "testing", rest of the items are not diplayed in the listbox why?Is there any limit for dropdown list items, If so how to increase the limit?
