VS 2008 - Activating / Disabling Controls Based On Date
Mar 19, 2009
I have this form with a bunch of input controls. I have code working that will disable them all like I want, but need to work with the if/then statement portion. Basically, it's a "History" form for patients. There's a date field for each entry, and if that date doesn't match the date you're accessing the form I want it to disable all controls so you can't edit the form. So it would have to check the current date with the date that is on the form. Then I also want to have an override button that will ask you if you want to enable all controls anyway, which I can probably figure out. There is some older VB6 code (I think) but I know nothing about VB6 or how it translates.
I think this is the portion that does what I want in VB6:
Private Sub DATE_DblClick(Cancel As Integer)
Call Setdate
Exit Sub
Dim sysDate As Date, Response
sysDate = VBA.Date
[Code] .....
How to have the program check the current date with the date in this form. From there it's probably just a simple if/then statement to fire off either sub. This date control on the form is a DateTimePicker. Maybe I just have to compare that to the system date but I still don't know what to call for that.

I have most of this working, but there are some issues yet. Basically, it's a "History" form for patients There's a date field for each entry, and if that date doesn't match the date you're accessing the form I want it to disable all controls so you can't edit the form.So it would have to check the current date with the date that is on the form.The issues I'm having are this. It seems to work because when I click today's date nothing gets locked like it used to, but when I do click another date everything in that form gets locked, including the override button and the scrollbar. I don't want the scrollbar locked, and I want to have an override button so the user can edit the form if they truly wish. It also locks the DateTimePicker so I can't pick another date, I don't want that locked either.I tried enabling the DTP in the sub below but it must get ignored

i have this function to enable disable the controls on a form....
Private Sub EnableDisableAll(ByVal xType As Boolean)
Dim ctl As Control
For Each ctl In Me.Controls
If TypeOf ctl Is TextBox Then
ctl.Enabled = xType

im trying to disable a button until anything has been entered into two text boxes simultaneously.
So far i have tried:
If String.IsNullOrEmpty(TextBox1.Text & TextBox2.Text) Then
Button1.Enabled = False
Else
Button1.Enabled = True
End If
However it doesnt work simultaneously, the button will become enabled if i enter anything into either textbox, i cant have any of them left blank.

I was looking for quick assistance with disabling the write button based on wrong user input. Program works great just feel like it needs a little more.

I don't like validating through the TextChanged event either as I believe that to be the cause of some issues. Doesn't the Textchanged event validate on each time a letter is typed?

I have a datagridview with several columns, but what I�m trying to do is sum km2 column based on date. I�m using the following
Private Sub Form3_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Me.CadastroSeqTableAdapter.Fill(Me.Db01DataSet.CadastroSeq)
[Code]....
The query is grouping by DATE (data), this OK, but the km2_FF values not, is not showing anything. To be more clearer, this datagridview has different values of km2_FF for the same date, I want to display the total of km2_FF for each day.

I'm working on a winform which contains several controls like textboxes, radio buttons, datagridviews... All of these controls have been added to a main group box called gbDataEntry. My problem is when the user is seeing the form, I set gbDataEntry.Enabled = False but I want to enable some controls like DataGridviews so the user can scroll them. After disabling gbDataGridview I set DataGridView1.Enabled = True but it seems that the datagridview does not respond to this line. Why?

A recent project of mine has been to make a designer. I've finished everything, but when I click the controls to show the properties window, the control interacts with the cursor. So my question is: How do I freeze the controls from interacting with clicking or key presses without disabling the control itself?

Would it be possible to search a table, confining to a specific date range based on a date-time column, and get a count of the 10 most used words in a particular var-char column excluding a list of words?All in SQL?Currently I am pulling out the records that match and sorting through the contents outside of SQL, I would think where I can do it directly on the server it would be more efficient.(SQL 2008)

I had this question before "Resize image on the fly make the image lose quality online but locally works nice".And what i got now is that it's not a problem of local or online, i ran this resize on the server itself "dedicated server", and i got the same bad quality image, so the problem is in the IIS configurations.What in iis can make this bad quality image happen?

I am looking to create several custom controls (PictureBox Derivatives) on during runtime. I've read that the best way is to create template controls that will be created, and duplicate them in the Controls array.
Well, that's all fine and dandy, but what's the best way to store the template? I considered a seperate form with all the templates laid out on it for easy access for my editing, and keeping them out of the user's sight. I also considdered doing a Struct for each template, and smply mirroring values onto the control being created from the Struct to the created control.
I'm looking for ease of development first and foremost, as I'm most likely going to have a vast number of these templates, and keeping the system as simple as possible will eliminate a lot of hair-pulling. After development ease, I'd go for optimisation.

I have a form with some textboxes on it. The textboxes show values from a table. I have a binding navigator that lets you step through the records in the table and the textboxes update. What I want, is to have a control, say a listbox, that allows you to select a value which will filter the data behind the controls so that you only have one record.
So, for example, say you have a table of contacts. There are textboxes on your form that show name, phone, address etc. You could then have a listbox that showed a list of all the contacts and you could select one, which would in turn the textboxes. The filtering field could be contactID for example.

Given a week number, I need to get the date of the Monday of that week.For example, I have several strings that are stored in a file, such as
"WK 28 2010"
"WK 30 2010"
They could be any any valid week number.
The Monday on Week 28 of the year is 12 July 2010
The Monday on Week 30 of the year is 26 July 2010
Its these dates that I need.
I guess I could create a lookup table, but would prefer a more smarter approach so my software will be future compatible?

is there a way to validate controls on a form, where the validation rules themselves are stored in a database table?My problem is my application is used to submit forms to mulitple government agenices both local and state level. Every entity seems to have there own rules about what needs to be in what location. i would like to not have to code all of the various rules for all the different fields. My thought was to store them in a database table and then perform validation based on rule table lookups...however I would like to use the .NET validation controls.
