I have a combobox on a form. Clicking on a particular label should hide this combobox. The problem is that if the combobox has focus, clicking on the button which hides this combobox gives error.How can I resolve this runtime error?
Move the focus. If necessary, create a very small control to receive the focus.
Me.SomeControlThatIsNotTheCombobox.SetFocus
Re Comments
Note that this label is not associated with a control.
Private Sub Label1_Click()
Me.Text1.SetFocus
Me.Label1.Visible = False
End Sub
I know this is an old post, but I recently just ran into a similar issue (and this post was in the first 4 or 5 results). If the control you're trying to disable is the first on the subform, try setting its Tab Index to 1, not 0. As soon as the subform gets the focus, the first control on it does, too. I was trying to set this during a Form_Open event, and this solved it.
Rather than setting focus to any particular control, which may cause maintenance issues in the future if the controls on the form change, if you simulate a key press of Tab then focus will move to the next object in the tab order.
SendKeys "{TAB}"
DoEvents
Me.Command4.Visible = False
Note the doevents is necessary to allow the processing of the Tab.

For the time being, this is a Material-UI question.
I have a situation where the tab key ceases to move the text cursor between TextFields. At the moment, I have no idea where in my code this is happening, and I am hoping someone can point me in the right direction so I can start looking.
Here’s the setup:
A mouse click causes a Dialog to be displayed. The Dialog has
several TextFields as well as 2 FlatButtons, “cancel & “submit”
At this state, tabbing between fields works as expected.
If I hit the “cancel” button, an event is fired which updates state (including the display of the Dialog) and the Dialog is closed. I can repeat the process from the top with no issues.
If I hit the “submit” button, an event is fired which does some async stuff (using rxjs epics).
On success, the epic fires an event which updates the state (including the display of the Dialog)
If I now try to repeat the process from the top, the tab key does not respond.
I am in the process of migrating to v1, and checked some of the v0.* components – they have the same problem – I don’t recall that being an issue before… Possible conflict between the two versions of the library?
Figured it out. Yes, there is a conflict between the v0.20 and v1.0 of the Dialog component. At least when you have one opening on top of another. Having changed all Dialogs to v1.0, the problem disappeared.
By the way, its not that the tab key wasn't responding - it was responding in the lower Dialog component and not in the top (latest to be created) one. This problem disappeared once the same version was used for both.
MS Access Development Question:
I have 3 options and I need each one associated with a different set of objects. Therefore, if you click option 1, a set of objects will appear in a box I'm referring to as "Report Parameters". If I click option 2, the objects in the "Report Parameters" box will disappear and a new set of objects will appear.
I didn't want to write code to switch each object from visible = true to visible = false. I thought that would take too long, especially if the number of option buttons or the objects related to it grow.
So I'm trying several things...
I tried putting all objects, that relate to a particular option, in a Subform. Therefore, I would have three subforms and that would sit in the same position on my main form. When you click on an option, the subform for that option is made visible any anything else is hidden. But I have a background picture that needs to be visible on the main form and you can't make the subform background transparent.
I used Tab Controls; however, I didn't want to use the tabs to control the switch between objects. I can hide the tabs but you can still switch between them if you click the space where the tab should be. It can be made transparent though so that helps a lot.
I need something in-between a Subform and Tab Control but I've hit a dead end. Does anyone have any other suggestions or recommendations? Or am I stuck coding for each object?
I'm an experienced VBA developer. My last option was to run a query against the form and pull all object names and save it to a table. Since the syntax of the name for each object connects it to a button, I can always run a loop that makes all objects visible/invisible if the object's name corresponds with a specific option... but... I guess I'm trying to find a shortcut. Let me know what you think! Thanks.
I was able to resolve my issue. I just needed to do some thinking... so writing up this question was a bit premature. I'll write down what I did in the event that someone has the same issue I have.
First, I used the Tab Control object to resolve my issue. I made the control transparent and named each page to reflect the Option Button I was selecting.
I then mapped each option to a button in the VBA code of the button. Therefore, when the button is selected it does several things.
First, it makes the default value of any of the other options equal to false. I also set the visibility of their corresponding pages to false.
Second, I select the page I need visible and set the visibility to true. I also make it my active page.
Lastly, as a safety measure, if the option button is already selected, and you select it again, by setting the value of that option to true. This is to prevent it from changing to false. One option should always be selected.
Hope that all made sense!
I have a main form...imagine that...that for most of my users will be the only form they use. Naturally, it contains tabs with sub forms.
I have a navigation sub form on the left side of this form that changes based on the user's rights level. Currently, this sub form is all buttons...and 1 always is selected as the default tab stop for that form.
I don't want to highlight any of them at first...and I can remove the highlight by switching off Tab Stops for all buttons. However, I'm not sure that I want to remove that functionality all together...and it still highlights a button. I'd just like for there to not be a default button highlighted.
As you can see, Add Course is 'selected'. I can't seem to find the correct terminology to search for a way to do this. I tried using a smaller button set behind another button, but since it has the focus, it moves to the front. Using a text field with the same colors as the background shows the cursor in a random, blank area...not visually ideal.
I'm sure that there is someone here clever enough to have this figured out. Please enlighten me. I don't care if this can be handled in VBA code or through design view.
"Focus" is the word you're looking for - you don't want any visible control to have the focus when opening the form.
The easiest method is an invisible button: create a button with Transparent = True, and an empty OnClick (i.e. the button does nothing, even when accidentally clicked).
Move this button to the top in the Tab Order, so it has the focus when opening the form.
But if your users use TAB to walk through the buttons, there will be one position where the focus disappears (when circling around from the last to first control). I don't know if it will confuse them.
Create a button on the main form itself.
Named is cmdDummyButton with the following GotFocus event code.
Set the tab order property to 0 (ie first)
Make the button transparent.
This will cause no control on the form to have the focus when it starts up.
Private Sub cmdDummyButton_GotFocus()
Static IveHadFocusAlready As Boolean
If Not IveHadFocusAlready Then
Me.cmdDummyButton.Enabled = False
IveHadFocusAlready = True
End If
End Sub
Sweet.
I'm trying to build a Wizard framework in Windows Forms. I've managed to glean a lot of useful tips from this and other sites which have gotten me very close to success. However, I'm having a problem with displaying an ErrorProvider on any tab page other than the first page of the wizard.
My Wizard control is a UserControl. It contains a custom tab control that I've derived from TabControl so that I can hide tabs and ignore attempts to navigate between tabs using keypresses, along with the usual collection of Back/Next/Finish/Cancel buttons at the bottom of the control.
I've used reflection to allow me to raise the validation events on a particular TabPage that belongs to the Wizard Control when I hit the Next button. (I don't want to validate the whole TabControl, only the currently active page.) When I do this, I see in the debugger that my Validating routine for the controls on the current tab page is correctly called and I see that I've called the ErrorProvider that I've attached to the particular control (a TextBox in this case) with a valid error message. I set Cancel to true for the CancelEventArgs in the validating routine and that's picked up by the code that uses the reflection mechanism so that I see that I've failed and don't change tabs. And I set the focus successfully to the control that failed validation.
So all that appears to be working just fine.
Unfortunately, I don't see the ErrorProvider's cheery blinking icon unless I'm on the first tab page. For all of the other tab pages, there's no message visible at all.
I'm baffled. Any thoughts? I can provide code snippets, if helpful.
Thanks!
I assume that in your case the button that moves to the next step of the wizard is placed outside (below) the TabControl
I noticed that the icon is displayed correctly if I pressed the button without releasing the mouse button. It seems that the button outside the container gets focused event though a validation error has occurred (normally you would not be able to leave the active control).
I worked around this issue by registering an event handler for the buttons MouseUp event to "refocus" the TabControl:
private void cmdOK_MouseUp(object sender, MouseEventArgs e)
{
tabControl1.Focus();
}
Note: you also need to set your forms ActiveControl property the one of the controls that failed validation.
I've been digging all over Jasper documentation and can't find the answer.
Currently for our reports, we have a simple input control, Date. When this launches, I am given a date control and at the bottom, I get series of useless button choices...
Apply, OK, Reset, Cancel, Save
Can anyone help me get these removed? Just want OK and Cancel. I looked at DefaultParametersForm.jsp but am having a hard time finding anything useful there. I'm an amateur jsp programmer.
We removed the Cancel button from the input control popup, we found it in the file inputControls.jsp in the jsp/templates directory.
You should find the apply, ok, reset and save button here also.
I do not know off-hand how to remove the buttons, but these buttons are not all useless. Reset clears your fields back to their defaults (blank if no default).
When you are using the Control Layout 1, you may think the Apply and OK button do the same thing but they don't. Apply will run the report with the set parameters, but will not get rid of the dialog box. OK runs apply and removes the dialog as well. (Note that the dialog can be dragged out of the way.)
If you switch to one of the other Control Layouts (I like 4), then the OK button goes away b/c there is no longer a dialog. You will only get Apply, Reset, and Cancel.
