With one of my event handlers (double click cell contents in a gridview) I bring up another form that gives a summery of the contents of the row that was clicked...
When doing this, I set the original form to disabled, so that the user cannot interact with it until the summery form is closed.
Problem is that I would like to keep my labels on the original form white, but being that they are disabled as well.. they turn grey, as they are supposed to.
I have tried to set their color with the event(enabled has changed) But my half-witted solution didn't get me the results that I was looking for..
Sounds like what you're actually after is a modal form. This forces the user to only interact with the new form you've opened (within your application) but they can still read what is behind. The following link is a good start:

In access-VBA I want to change the background color of a CommandButton called "schmultiform"
So I tried to change it in the properties-window with no effect. The background stays in light grey whatever value i put into BackColor.
Then I used the following code in Form_open
Me.schmultiform.BackStyle = 1
Me.schmultiform.BackColor = RGB(255, 0, 0)
but it had no effect.
I created a new access-file, made a dummy form and put a button there. The background of this button I can change as I want. When I copy&paste the dummy-form from the test-db into my original db, the button behaves like the other one before: Its background-color switches to lightgrey and its not changable anymore.
So I supposed the problem is in the database. Maybe there is some kind of default-style or something else but I couldnt find anything.
Any suggestions?
Update:
I found out that there are differences in the properties of the dummy button in the test database and the original button:
A property "Use Theme" is available in my test-database but it is missing in the properties window of the original button in my original database.
Changing "Options menu >> Current Database >> Use Windows-themed controls on forms." to true will change the style of my buttons but its still not possible to change the backgroundcolor of buttons.
The creation of the original database was several years (maybe >15?) ago.
Have you upgraded this database to the newest version? In order versions of Access you couldn't change BackColor for a command button.
I am writing a Windows Forms application in VB.NET. I have three forms: the main form, which shows a list of accounts, the account form which allows the user to view/edit the information for a specific account, and the policy form which allows the user to view/edit the information on a specific policy for that account. I want the forms to appear as if they are all the same window. Example: when the application starts, the user clicks an account name in the list box on the main form and clicks "edit". What I want to happen is that the window stays in the exact same place and stays the same exact size, only the content of the main form appears to be replaced with the content of the account form. Same thing if the user then chooses to edit a policy from the account form. When the user finishes and clicks "save", the main form comes back up. Through this entire use case, it would appear to the user as if they were viewing the same window the entire time, with the content of that window changing.
How can I do this? I have tried something like:
Dim newForm as New AcctForm
newForm.Location = Me.Location
newForm.Show()
Me.Close()
The problem is that if the user moves the original window, the new window appears where the parent form originally appeared, not where it ended up.
I see this is already in the comments, but what I have done in this case in the past is build each "form" in the application as a custom control. Then I have one actual form, and navigation works by changing which custom control is currently loaded on the parent form. To move from one screen/view to another, you remove the current custom control from the form's controls collection and add the new custom control.
I believe this is superior to manually setting the startup position and size, because you can use the form's .SuspendLayout()/.ResumeLayout() methods to hide the interim state, where there is no control loaded, from the user. This is harder to do when you want one form to be completely replaced by another.
This also makes it easy to set certain form properties in one place and have them be consistent for the application. You can even have an area on the form with controls that will now show in every view.
When using this pattern, I typically have each of my custom controls inherit from a common base. You may not have anything specific you will do with that base at the outset, but it almost always comes in handy later.
Finally, switching to use this scheme is easier than you think. Just go to the code for the each of your current forms, and you will find that each class currently inherits from System.Windows.Forms.Form. Most of the time, all you really need to do is change them to inherit from System.Windows.Forms.Panel and you're most of the way there.
As others have said, it may be better to redesign your application using custom controls or panels etc.
However, to answer your question regarding the seemingly random location of your forms, the first thing to check is that each form has it's StartPosition property set to Manual.
If your main form is resizable, then I would also add code to adjust newForm to the same size too.
I hope that helps with your immediate issues; so that you can move on to redesigning the application!
good morning there is another way . set property for second form to (top most) and use also
from2.show();
that make you switch between forms and keep form2 top other
Thanks
try using ShowDialog()
Dim newForm as New AcctForm
newForm.Location = Me.Location
newForm.ShowDialog()
Me.Close() <-- removed this
Needing some help attaching an Excel/VBA button on an Excel sheet. I need it to stay in the same position on the screen regardless of how I scroll or zoom. Preferably, I need this on the bottom left or right of the screen.
I have tried adding a button. Then, I right clicked on the button. Clicked on Format Controls -> Properties -> selected Don't Move or Size With Cells. Am I missing something that's making this not work?
Thanks!
I know this post is old, but here's to anyone it could be useful. The VisibleRange property of ActiveWindow can solve this problem. Use something like this:
Private Sub Worksheet_SelectionChange(ByVal Target As Range)
With ActiveSheet.OLEObjects("MY_BUTTON'S_NAME")
.Top = ActiveWindow.VisibleRange.Top + ActiveWindow.VisibleRange.Height - 5
.Left = ActiveWindow.VisibleRange.Left + ActiveWindow.VisibleRange.Width - .Width - 5
End With
End Sub
Here is the idea that I put across the comment earlier today :) Typically we can get a Floating User Form by setting the Modal property of the form to be 0 which is indeed a Modeless state.
Basic Points to consider:
Look & Feel of the form to make it look like a Button (Not show title bar/Not Resizable/
Hidden Close Button etc)
Setting the position of the Button
Which Event should trigger the form-button (WorkBook Open)
What would you do with Form Initialize Event
Whcih Events should keep it stick to the same position alive
Further Points to consider:
You might only want to keep this button vissible for the workbook you are working, and if you open another instance of a workbook, do you still want to keep the button
If you minimize the Excel Window instance, how do you plan to manage the state of the button and keep it visible
Post about keep displaying a form even the workbook is minimized.
One other great reference I happend to see, (little bit technical) but worth the shot - at least to get to know the certain properties/methods that you could make use: Extending VBA User Form Control.
The article include the following info, and please note the last line as well :)
They give you access to capabilities that are not available from VBA or from the objects (UserForms, Workbooks, etc.,) that make up a VBA Project. When you call an API, you are bypassing VBA and calling directly upon Windows. This means that you do not get the safety mechanisms such as type checking that VBA normally provides. If you pass an invalid value to an API or (a very common mistake) use a ByRef parameter instead of a ByVal parameter, you will most likely completely and immediately crash Excel and you will lose all your unsaved work. I recommend that until you are confident that your API calls are solid you save your work before calling an API function.
Add new Row on the beginning of your WorkSheet and set your button on it, then:
Freeze Top Row
Right click → properties → placement → change to 3.
Hi I have a VBA application with a combobox selection option.One of the combobox option is Other which when user select that option an invisibled label will pops up and prompt the user to fill the txtOther control.now my question is how I can get rid of the prompted label and make it to invisible after user fill the txtOther and move(focused)in other control?
here is a shot of my app:
Thanks for your time and help
It depends on how often or when you want the check to be done. I couldn't find a good reference to show you all of this, but you can view your VBE.
Within the code behind your userform you can use events for the text box.
If you want the check done every time you leave the text box:
Use the TextBox_Exit event.
If you want it to fire whenever the contents are changed, used TextBox_Change. There's lots of options, but based on your explanation I'd probably use Exit.
This answer shows some syntax examples for using the Textbox_Exit event.
Ok so this maybe a simple/silly question but I don't know so here goes:
In access let's say I want to have a frame control, so I click the option group button and add it to the desgin surface. However, I am not wanting to use this as a option group with radio button selection, instead I would like to add text boxes instead the frame, so that when I reference the frame, it references every control instead of it, hence the text boxes, cbo boxes, etc.....just as it would if they were radio option selections.
So can you do this?
I want whatever controls I add inside the frame to be easily referenced (i.e. make all controls visible just by using frameExample.visible = true) so that I can build my own tab control groupings.....
can this be done?
Thanks!
EDIT:
What I am trying to accomplish is having a form that includes a collection of controls (input controls - cbo boxes, text boxes, etc), that serve as the Main record information. These are saved to a table via an INSERT statement on button_click because this form is unbound.
Next I have 8 categories that are relative per each main record (and data that goes along with it). Each of these categories could have a sub form area and a button click that bring it's relative form into the sub form area. These sub forms would be unbound as well as I would just save data via SQL statement. So i know I could accomplish this by running the insert statement from the parent form, on the main collection control's data that would create the KeyID number, then run a SQL statement that would turn around and load that KeyID number right back onto the page in a hidden text box.
Then when I click one of the sub forms and load its relative collection of controls, I could then save that data along with KeyID for each of these sub-forms/tables.
SO......
I was wondering if instead you could define these controls as a collection so that you could hide and make visible all the ones you need on button clicks and avoid the need for additional forms (subs). I know that if a user enters data into a text box, and then somewhere along the way that box becomes hidden, the data still exists in it and still ends up in the SQL statement....
So I want all these controls to exist on the same form, but I thought what is I could encapsulate them into a frame like an option group, then I could call the frame and all the relative controls would be called up (made visible) as needed.
Sorry for the long explanation but I thought it would help.
I do not think you can do it with an Option Group, but what you are describing is pretty much a subform, yesno?
Some examples of hiding the tab control from an app that went live in March 1998:
Tab driven by transparent command buttons over labels styled to look like colored command buttons:
Same approach, more buttons:
In this case, fake colored command buttons don't drive the tab, but insted show/hide the tab and a subform. In this case, the tab is actually driven by the listbox:
A view of when the tab is hidden and the subform revealed. The listbox drives navigation within the subform, which has a visible tab on it:
So, there's a lot that can be done without showing the tab control.
