I am trying to filter a dataset using a number different inputs, selected by a number of check boxes. I have all the text base rowfilters working, but I can not make the date filter work unless I hard code the datetime into the code. The database is MS Access and I am using VB2008 to show the data. I would like to be able to use a DateTimePicker to set the filter date (without the time part) Also I would need to remove the time section of the datEnterDate. I cannot change the structure of the database fields. Also the datEnterDate is MM/dd/yyyy, because I'm in England I would like to use the format of dd/MM/yyyy if possible

i'm new at vb.net (though i have extensive vb6 experience and oracle experience), and i need a sample program/project which uses multiple queries (of the same oracle database namespace) to display counts in text boxes.user will use a pull down list to select action from there.
View 1 RepliesI have a timer that basically counts a number up in sequence in a label. On the On Text Change sub for the label I have functions run when the label is at a specific number. Everything works fine, the only problem I have is I have information pulled from an ODBC link to a pervasive database every second, which slows down the program. I have several flash components that run so slowly because of the data update. Now I have tried both using a dataset and coding the query but it is still ver slow and processor intensive, I think its because the Pervasive ODBC link is somewhat slow. Is there a way to have my data pull timer run in the background so that it doesnt effect the performance of the rest of the program?

Write a program that counts the number of spaces in a string provided by the user
-You need to use the InStr function and start it at different points within the string on each loop of the Do Until control structure.
output- needs to state how many spaces that are in the string that was inputed in the text box

View 4 RepliesI have a form which contains a large number of textboxes covering numerous panels/tab controls and I would like to have the user only have one text box visible at a given time and when the user clicks on the screen to another label with a corresponding text box I would like that to appear and the other currently open to disappear. Currently I have the following loop that goes through and changes the visibility of the appropriate controls unless it is the name of the control I am looking for:
'This is used to iterate through all the controls in the form and ensure the visibility of all other controls
' than the active control is set to false.

I have a Windows form which contains a DataGridView within a GroupBox which is within a TabPage which is within a TabControl.The scrollbars property is set to 'Both' so that the user can scroll down to see all available rows in the grid.
I want the Windows Form to initialize to allow the user to see 7 rows but to expanded vertically to the size of 32 rows which is the maximum possible in this application.
Is there a way to size the form dynamically so the Form's Height property can be changed as the DataGridView's rowcount increases?

View 5 RepliesI have created a basic query generator which allows a user to select the Select, WHERE and criteria attributes using a number of checkboxes.However i have got stuck. In the results form i have the following code
Private Sub DisplayRecord()
RichTextBox1.Text = ds.Tables("newResults").Rows(intCurrentRecord).Item(0)
RichTextBox2.Text = ds.Tables("newResults").Rows(intCurrentRecord).Item(1)
RichTextBox3.Text = ds.Tables("newResults").Rows(intCurrentRecord).Item(2)
[code]....
The program keeps on crashing if the user does not select the corresponding amount of display records from above for the amount of attributes they want for the SELECT part of the query in the intreface in form 1.
How would i go about making something where the number of SELECT attributes selected which are listed in a string create the correct number of textbox fields in the results form (form2)
I am trying to make a basic ATM system, iv got all the interface done and I have made the link to my SQL database etc. the part i'm stuck on is how I can run a check to see if a bank card number matches up to the users PIN number. To simulate the user putting a card into the machine I've used a combo box, and that lists all the cards, that haven't been flagged as confiscated (there's a column in my ATMCards table that I can set to true or false) then after the user has selected a relevant card there's another text box where they can enter in their PIN number.
Now what I want to do is, if they chose the card number 1234567890123456 in the combo box and they enter in the PIN 1234 into the text box, then, after clicking the check PIN Button if the pin is correct they need to be taken to another from where they can check their balance etc., and if its wrong they got three attempts after which point i want to flag that card as confiscated.
I got 2 LABELS and ONE BUTTON... when i press the button, it fills both labels with a random number from 1 - 6.ild like to do it like this... you press the button then a little prograss bar starts running for 3 or 4 seconds... and THEN after it reached the bars max i want it to show the numbers in the Labels...
the second thing is...i want to make 2 checkboxes next to the labels... if you mark the first checkbox, next to the first label... and the outcome is that the number of the first label is BIGGER then the other one.. you should get some kind of a msgbox.. i know how to make a msg box... but i dont know the code for vb to check if label1 is > or < than label2....
Most of my check boxes look like these (on the left of the picture) (ignore the checked check box in the upper left corner , I am not talking about tat one) :However , ONLY on tab 2 the check boxes look differently in both cases the check boxes are Disabled , but they don't look the same . Why is that ? I even tried copying the check boxes from tab 3 to tab 2 but to my surprise they once again looked differently ! This only happens on tab 2 . How is this possible ?

I've got a screen with 4 group box and several text box inside them.Each group box is controlled by a check box, so if the check box is true, the group box is enabled. Otherwise, the group box will be disabled.So far, I've been using a 'Refresh' button to evaluate the check boxes values.Now I'd like to give up using that button, so if when I change the check box state, so will do the group box. How could I do that?

View 2 RepliesUsing Studio/VB 2010 here and would like to find out how to approach the following. Examples would also be welcomed as I've not yet tried the progress bar control.
Scenario: A windows form will contain multiple check box controls that will be "auto-checked" as other parts of the user application/interface are completed. I would like to show a progress bar on the form that will give the viewer some idea of what has been completed. For example, 5 of 20 checked-off would show 25% in the progress bar.
Is there a way to check if a number in a TextBox is an even or uneven number?
