I have a program with three Textboxes that have numbers typed in as text. I have them dimensioned. When I try to use them it gives me an error "Cannot convert a String to a Double". I have tried to use a=CDBL(textbox1.text) but that did not fix it. Is there a solution to this problem?
Sub Test()
Dim a,b,c
a=Textbox1.Text

I am trying to bind a textbox to a binding source (using the IDE DataBindings Editor) and it works fine except for one thing: if I delete the text I get the subject error. What I want to happen is the datarecord field be updated to a dbnull value -- how do I get that to happen?
View 4 RepliesSo what happens is. I have this JAVA Code which i am making out of a vb form to help me develop quicker in that. So, when i click "Button1" a formula enhances and gives an output "TEXT" Which i want to choose what lines it shows on my "MultiLine Textbox".
Basically, How do i make it so when i click a BUTTON a text is written in a MULTILINE-TEXTBOX which i get to choose which bits of the text goes on which line.
the example is:
("this goes on line 1")
("this goes on line 2") ect.

I'm using VB 2008 and reading data from an access 2003 database.I have a query setup in access - read in as a 'view' in vb ... that is showing results of first pass yield. total good parts... total bad parts... and percentage of yield.in my access query - i have the percentage displaying properly using the column format in access... however - on my form - the data source comes in as a textbox...by default.I can't seem to google the right question - but right now on my form, even though the dataset recognizes it as a double precision number - the option in the datasource tab - shows it as a text box or data grid right ...
so on my form i have the text box or details option... but my text box shows the percentage as a long decimal ... .98936524 or whatever... what's the correct string i need to format the textbox.text to display a percentage?I tried format(val(textbox.text), 0.00) that didn't do anything... and I did this under the form load section after the data sets were filled.
I am trying to format a string of arbitrary length into a fixed width field for display.
Let's use a width of 20 as an example, and call the string to be formatted s. I'm adding the formatted string to a StringBuilder named b.
Dim b As New System.Text.StringBuilder()
Dim s as New String
If the string I want to display is shorter than 20 characters, I can do this:
b.Append(s.PadRight(20))
or
b.AppendFormat("{0,-20}", s)
So far, so good. But, if the string is longer than 20 characters, I want the string to be truncated to 20 characters as it is appended. The code above appends the entire string.
I tried this:
b.Append(s.Substring(0,20).PadRight(20))
But, this fires an exception if the string was shorter than 20 characters.
So, I ended up with:
b.Append(s.PadRight(20).Substring(0,20))
This seems to do the job. The PadRight prevents the exception by making sure thet string has 20 characters before the Substring is performed.
I was wondering if there is an alternate method that would look more elegant and avoid padding the string just so prevent the substring from causing an exception. Have I missed a feature of String.Format that can accomplish this in one step?
Edited to add solution:
I ended up with the following code:
Module Extensions
<Extension()> _
Function AppendFixed(ByVal b As StringBuilder, ByVal s As String, ByVal width As Integer) As StringBuilder
[Code]....
This uses an extension method to clean up the syntax, as suggested by Joel and Merlyn, and uses the StringBulider Append overloads to avoid creating new strings that will have to be garbage collected, as suggested by supercat.
I have one data grid which contains a column which contains long string values. When I edit it, the text box which appears is very small. I want to increase the length of text box.
View 2 RepliesI am using ms-access 2002. I have to export the data of a ms-access table in Fixed Width format. To accomplish this I am using DoCmd.TransferText method.
DoCmd.TransferText acExportFixed, "schema.ini", "table_ABC", "C: estingTestData.txt"
But I am getting error message: "Run time error-3625 The text file specification 'schema.ini' does not exist.You cannot import, export, or link using the specification."
Here schema.ini is at same location as of text file. i.e. "C: esting"
I tried with
DoCmd.TransferText acExportFixed, "C: estingschema.ini", "table_ABC", C: estingTestData.txt"
but no success.
For delimited format it is working fine
DoCmd.TransferText acExportDelim, "", "VDMMEMBS", "C: estingTestData.txt"
I have gone through the link [URL]
Error message is same as of me but example shown is related to import of txt file.
I am having trouble getting the Student Name entered in the Student Name Form to change the Text titles of the GroupBox's on the Main Form and Schedule Form. I understand the logic of what needs to be done to some extent, but I am having trouble coming up with the correct coding.

what method would i need to override with a custom XmlElement to format the body in a certain order?Currently, when the class is instantiated, i have it auto-fill the Default Value from the DefaultValueAttribute and create the initial child elements through the constructor.What i want to do is make sure that the Elements child nodes are in a certain order. This is not a webservices Xml Transformation but a simple file output for a User Interface.
I tried overriding InnerXml but that was a bust. If i dont create the initial child elements from the constructor then they never show up.

Actual output would not be in a XSLT format but this should get the format i am looking for. Currently, what ever is edited last is at the bottom, and i want to have the various object properties to be outputed in a certain order in the ChildNodes of the parent. I want to have the iteration overload to a minimum. I would rather handle the childnode creation be handled on the output of the class into XML format.
I have a textbox whose max length is 30 but the width of the textbox is 250 (bigger than the max length). I want to center Align the textbox so that the text starts at text length 15 of the text. I tried using the Text Align property of the textbox, but it starts the text at the center of the textbox. Is there a way to accomplish this? I want to make it a default setting for the textbox.
View 7 RepliesMy app outputs to printer and after much effort (and assistance from this forum) I got the print output formated to an acceptable output, except when certain user choices make for a multi-page document. The document prints one page and then cuts off. We formatted the output using a defined rectangle (the code for which I do not fully understand) to format the page. Can experienced users give me some help on getting a multi page output?
View 1 RepliesIs there any easy way to adjust a width of TextBox in this way:
- minimum width is 80,
- maximum width is depending on font size and number of characters?
The textbox is read only.
m trying to calculate the width of a textbox given x number of characters. So how, given a random instance of a textbox and a random number of characters, can I calculate this? little extra spacing is allowed - for example if you were basing the widthupon the greatest width of a character given the current font. Actually, this is preferable
