userform

Task My intention is to write back UserForm Listbox data to a sheet range in the most efficient way using the data field method. Basic Method (esp. using data ranges) AFAIK the most efficient method in order to write data to a range is using arrays. If data originate from a range it's preferrable to use data field arrays, which by default are two dimensional ( one based arrays ) and allow to a) get data from sheet to array or b) write back the array to sheet with one code line: Dim v ' As Variant Dim rng As Range Set rng = ... ' a) range to array v = rng.Value ' b) array to range rng.Value = v

I'm trying to add options to a combo box in a userform. When I run the code, Excel doesn't give any errors, however when the userform shows up it doesn't display the entities I have added to the combobox previously. That is, when I click on the combobox, it doesn't show any options, only one blank row, as if no items were added to it. Here is the code I'm using: Private Sub UserForm_Initialize() ComboBox1.AddItem "xxx" ComboBox1.AddItem "yyy" ComboBox1.AddItem "zzz" End Sub I am using the following code to call the user form within a macro: UserForm.Show Dubeddo The code given in the question

When adding controls to a userform, what is the difference between the following. I am confused as to when it is appropriate to use any particular one of these. Dim aButton1 as MSFORMS.CommandButton Dim aButton2 as Control.CommandButton Dim aButton3 as CommandButton Add UserForm first . Then in VBA IDE press F2 , the object browser appears. In the upper left corner is combo box, select MSForms . In the classes list you can see the classes which belongs to MSForms object library. You can see CommandButton and Control in that list: To declare a variable of type CommandButton in your code: Dim

How can I call UserForm_Initialize() in a Module instead of the UserForm code object? From a module: UserFormName.UserForm_Initialize Just make sure that in your userform, you update the sub like so: Public Sub UserForm_Initialize() so it can be called from outside the form. Alternately, if the Userform hasn't been loaded: UserFormName.Show will end up calling UserForm_Initialize because it loads the form. IMHO the method UserForm_Initialize should remain private bacause it is event handler for Initialize event of the UserForm. This event handler is called when new instance of the UserForm is

Background: I have a VBA userform with ~1050 checkboxes, and ~100 labels, all populated from the active Sheet. The labels are taken directly from the sheet, based on the ActiveCell.Row (t and i are the rows of specific information in relation to the ActiveCell, where there are 20 different tables on the same sheet where the userform would be pulled from when double-clicked). The event to load the userform ("Stb") is a doubleclick event which doesn't appear to cause the issue. Issue: Seemingly random, Excel crashes stating I am using too much memory, that I should use the x64 version if I keep
