VS 2010 Set The Maximum Number Of Digits Before The Decimal?

Sep 2, 2010

Im wanting to use a textbox for the entry of Decimal figures (currency). Is there any way I can have it so if a user does not put a decimal figure (ie 15 instead of 15.00) it will put it on.

I tried a masked textbox, but that means i have to set the maximum number of digits before the decimal too which is no good.

VS 2005 Getting The Correct Number Of Attributes To Match The Correct Number Of Text Boxes?

Apr 18, 2009

I 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)

Decimal To Binary Using Colour Boxes?

Feb 2, 2010

I'm doing a uni assignment regarding changing decimals to binary. However this assingment seems to be different to most of its kind from what I can see.Our assignment asks us to have a text box in which we'll enter the decimal, then we'll use a menuscript to and highlight the button 'dec-to-bin' which will then change the colour of 8 image boxes (located in a row above the text box) from black to red based on whether the binary is '1' (Red) or '0' (Black) for that bit.I've struggling to find a starting point as I need to ensure I link the text boxes to the outcome of the decimal and binary but not sure how.

Filter A Dataset Using A Number Different Inputs, Selected By A Number Of Check Boxes?

Mar 3, 2010

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 need help getting the sum of a bunch of text boxes into another text box without using a button. Ive tried using TxtTotal = Val(txt1) + Val(txt2)... in the Total1_TextChanged but nothing happens. Someone once said I should use databinding but I cant see how that would work when Im using user input as the data to be Totaled. Also I dont know a whole lot about vb as I am just learning, and databinding

ps the values Im adding are in currency format. So I guess i would need to convert them back to add them, but im not sure.

String Manipulation - Separate Three Fields Of The Phone Number And Display In Three Separate Text Boxes?

I created a telephone number form where the user enters the telephone number in a text box as (nnn) nnn-nnnn.

I need to separate out these three fields of the phone number and display in three separate text boxes labeled appropriately.

VS 2010 Images In Rich Text Boxes?

May 31, 2012

In a program I'm planning to generate reports which I'll display using the rich text boxBesides rich text, i want to put images into the rtb. I've looked up how to put images into rtbs and the only way that i can find seems to be by pasting them from the clipboardThis method works well with setting bitmaps to the clipboard but i run into a problem when i try to set a metafile to the clipboard (the report contains plots and metafiles are perfect for that kind of thing). So if there could be another way of inserting a metafile into a rtb or maybe a way to write a rtf file with a metafile in it, that would be great.

.net - Use DataGridView To Populate Text Boxes On The Form .NET 2010?

I want to display (DataGridView's) selected row contents (each cell value on appropriate text box) on text boxes on the form. This should be fairly simple task for experienced i am sure.So far i haven't been able to find a single working solution to accomplish that as most of the articles are written for VB / VB 2005/ VB 2008 and not VB 2010.

Here is what i have already tried. (I tried putting an image but i can't due to my privileges over flow) TextBox1.Text =DoctorsDataGridView.CurrentRow.Cells(0).Value.ToString It strangely works for first 4 selected rows and populate text boxes but fails for the rest of the DataGridView.

VS 2010 : Compare The Data Between Two Text Boxes And A Variable?

Feb 27, 2012

I need to compare the data between two text boxes and a variable. If the value of the boxes don't match up and the variable is -1, I need to fail it.When I do this:

VB.NET
If Not Me.txtPcidSystem.Text = Me.txtPcidDatabase.Text Then

I have no troubles, but adding the variable check produces a false positive.

VB.NET
If Not Me.txtPcidSystem.Text = Me.txtPcidDatabase.Text And TestData.BypassCheck_PCID = -1 Then

The way the code is laid out, I have to do this in one line. I can't check the first condition on one line and the second on another.I've tried separating the data out with parantheses, but it's producing the same results.
