I 'm having no trouble coding, I'm back to my initial printing problems. The program printed Avery labels in a variety of sizes. I created the label templates on 8.5 x 11 forms and then printed the forms. This cannot be done in VB 2008 for a variety of reasons:
1) The form size cannot be larger than the screen size I got around this by creating a new form class that matched my dimensions.
2) printform only does screen shots. This was a major barrier. First of all I can't get printform to print my custom form because it's not a member of system.window.forms.form, it's a class in system.window.forms.usercontrol. However, even if it was in the correct class, it wouldn't work correctly because printform in VB.net, does a screen capture of the form and then reduces the image on the printout.
So that is my dilema. I do not know how to use the reporting tool, but I can see that it must be binded to a database. Although my application does use a database, I want to be able to massage the data before printing it. And the application does more than just print labels. There are also custom reports that need to be printed.
Basically on my form I have a listbox containing data. Under the listbox I want to place a button named "btn_PrintData" or something to that effect. The user will click this, the print dialog box would come up and bingo they could print the contents of the listbox.
I just wanna print my whole richtextbox using print document. I need to count words till the end of the page and so print them. And it must be bounded in a rectangle.(e.marginebound) from top,left,right and bottom. Also i don't know ho to use print preview. writing a proper print Document. It's the end of my Wordpad project and i just cant write a good printing!
I'm building an application that outputs a list of usernames to an HTML document. I'm using this to generate a string:
For y As Int16 = 0 To intBuddyList - 1 strBuddyListHTML = strBuddyListHTML & strBuddyList(y) & "<br />" Next
The resulting string is then put into an HTML document. The problem is, when I load the document, the brackets are displayed literally. When I view the source, I see this:
I have a block of code that has a test for a variable I use. The Code doesn't respond correctly when the variable Cph which is declared as a double is at 4.2.
HTML If Cph < 4.1 Then ElseIf Cph >= 4.1 And Cph < 4.2 Then
[[code]I have this issue where most of the rows in the table do not fill in the data to textbox2 and any edits made in the text box when this happens do not commit to the underlying datasource.When scrolling down and back up the datarepeater different records seem to be shown each time the data on the left is correct in the standard DGV ... it's just the data repeater that doesn't work.
I am having problems disposing of a image thats stored in a 'DataGridViewImageColumn' . When i try and delete the image the 1st one works then the 2nd time its used i get a 'System.IO.IOException: The process cannot access the file 'x' because it is being used by another process'. How do i solve this problem? i am disposing of the image before i try and delete it but yet its still not working:
PS - I have searched the forums / google for a suitable answer and cant find one
I recently made some obvious changes to one of my programs (added a few buttons, etc), and when I start debugging, it goes back and uses an earlier version before I made the changes.
I am trying to find a record in a table making use of a SELECT statement. It only seems to find the first record. NO errors are returned. Here is the code and a screen shot.
My debugger doesnt work correctly anymore and I want to let it work correctly cause i've done some changes in my project but when I click on debug then it just shows my old layout.
In order to multithread correctly, so that my UI gets updated and the background code functions correctly, I've been doing this:I have one sub that does the UI updating and checks for invocation: [code] However, I need to update the UI within the Class now. When I do that, my app is no longer responsive. I need to do all UI updating within the form class and all background code within my custom class.I just can't figure out how to determine at what part my class is at, to update the UI.The UI has a few labels and a picture box that needs updating. As it runs a new process, (about 8 in all) I need to update the picture box and labels with the appropriate information so that the user knows where the app is at.
I have been working on a quite complex multiform solution.All of a sudden the start up form (in fact any form I designate to start up) loads, displays and operates fine.
But when I try and show a form using showdialog the form displays behind the original form and I can�t set focus to the ide to close it down. I have to use task manager or alt f4 while the form has the focus.
Calling different forms from this one gives the same result but other forms work fine. I don�t want to redo this form as Ive done a lot of work onit.The only thing I can think of that whist I was changing the startup form in the project propertied page (file>project>properties) I unchecked the �Enable applications framework checkbox.
I have made a form that consists of textboxes nested in groupboxes nested in tabpages. I want to check if all textboxes are empty in every groupbox and even if the controls from a groupbox in a groupbox are empty.When they are empty i should not create an element string for my .xml document.Below is the code that I have at the moment. I call it with the form as the parameter.
Public Sub recurringControls(ByRef ctl As Control) For Each c As Control In ctl.Controls If c.Controls.Count > 0 Then If c.Tag IsNot Nothing Then
The PrintPreview dialog loads and correctly displays the correct number of pages.When the Print button on the dialog's toolbar is clicked, only one blank page is printed to the printer.Seperately, when calling the PrintDocument1.Print() method, all pages are printed correctly to the printer.[code]
I have been able to do the exercise's in the first 2 chapters and half the exercise's in the third chapter of the text book (programming in visual basic 2008, Julia Case Bradley & Anita C. Millspaugh). but this one is making my head want to explode. please point me in the right direction with this.
Heres the problem. The company has instituted a bonus program to give its employees an incentive to sell more. For every dollar the store makes in a four-week period, the employees receive 2 percent of sales. The amount of bonus each employee receives is based upon the percentage of hours he or she worked during the bonus period (a total of 160 hours). The Calculate button will determine the bonus earned by this employee, and the Clear button will clear only the name, hours-worked, and bonus amount fields. A Print button allows the user to print the form. Do not allow missing or bad input data to cancel the program; instead display a message to the user.
Here's my code so far. its giving me the wrong results. i have tried many different ways,(hence the commented code) but I just dont know where im going wrong.
Anyway, I was just wondering if anyone knows how to do these from a simple text box. i.e. 'TextBox1'.
I'm just learning VB and it's only a simple text editor but I can't find any good sites or posts that help me in understanding how to do it. These are not really covered in any of the 'beginner' books I have acquired either.
My instructor told us how to print documents and how to use databases. What the instructor did not mention is how to print or print a preview of records within a DatabaseDataSet. The book "Programming in Visual Basic 2010" does not explain how to print or do a print preview of Database Source records from within a form. The only thing I was told was to test the print document first before you try to do a print preview. Within a form I used a DataGridView to add, delete, and update the database. So now all I need to do is figure out how to print the updated records from the DataGridView and how to print a preview of the records within the DataGridView. So I hope my question is clear enough to give me assistance on how I can perform these two actions. Thanks this would be a great help, and since the class is online we can get assistance from any sources that we have.
I'm very very very new to VB.Net and am doing a class project. I want the user to simply clicka print button and get a printout of an existing Word document. Is this possible and if so, can someone suggest the code?
