I'm working on a project that involves localizing a large number of Windows Forms. We're dealing with layout using the TableLayoutPanel control, which works nicely. One area we're striking problems with is when we set the Form.Localizable property to True, we then end up having to manage one .resx file per form per language.
That would be fine if the .resx files only contained the Localized text, but it also contains a vast amount of layout data for the form. Is there a way to separate the localizable text elements from the control layout information, that continues to work in the visual studio IDE? I've noticed that I can modify my the form's designer file to look at another resource file, but when I use the form designer, these changes are deleted:
If I have a large number of classes, each similar to the other in certain aspects (they all share a common base class, but each does things differently), and I need to create Windows forms for each to allow easy changing of their values through a GUI? Create one matching form for each object in VS' forms designer, Or Use code to create the forms dynamically at runtime.
#2 makes the most sense to me, because a lot of these objects will share very common features of the form, notably "Ok" and "Cancel" buttons. But one object might need to draw a textbox on the form while another might need to draw a combobox. Not to mention, if I want to put icons on the "Ok" and "Cancel" buttons, I'd have to do this for each copy of the form in designer, and that sounds like it could get out of hand quickly.But is drawing forms through code sane? VS' forms designer is pretty sophisticated and designed to make life easier. Am I wise to consider ignoring its functionality and diving into the trench warfare of forms design through code? Or are there examples of automating form creation based on an existing object's properties?
Assuming that I have a Windows Forms textbox and want to reduce the maximum amount of characters that can be allowed in via user entry, how would I do that?
My VB application is behaving strangley. I have form with fairly large number of controls. I am using case against radio buttons. after curtain number of buttons, it stops responding to more radio buttons.
Then I tried to split controls in to 2 form but now my form.showdialog() too now working properly. It takes new from names but show the old form when running.
I am doing a bar cash register and I want to use a if statement to see if fosters button and number 1 on the number pad are both pressed then multiply constant by quantity number
I am getting Errors: Operator '<' is not defined for types 'System.Windows.Forms.Button' and 'Integer'.
Operator '>' is not defined for types 'System.Windows.Forms.Button' and 'Integer'. Value of type 'Integer' cannot be converted to 'System.Windows.Forms.Button'.
And my program does not work!
Below is my code..............
Private Sub ProgressBar1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles ProgressBar1.Click ProgressBar1.Value = TextBox1.Text End Sub
I am using VB Express 2008 and want to return the titlebar text of a window This is what I have:
Private Declare Function SendMessage Lib "user32" Alias "SendMessageA" (ByVal hwnd As Long, ByVal wMsg As Long, ByVal wParam As Long, ByVal lParam As String) As Long Private Const WM_GETTEXT = &HD Private Const WM_GETTEXTLENGTH = &HE
[code]....
This should simply return the window name I.e. "Calculator"But debugging it i get an "OverflowException" on:
strtmp = Space(length - 1)
If I look in the length variable it has "8975925931411505153" in it Why is it so big, and why is it not just "10" for the number of characters in calculator?
I've a situation where I am trying to extract a large number of URLs from a site, but the site which provides the URLs has an obstacle. Rather than the link directly to the site, they provide a link to an internal page, which automatically redirects me to the URL I need.
i.e. <a href="www.StartingSite.com/outgoing/1234" ...> Example.com</a>
which passes me to an internal page, then automatically routes me to Example.com
I've suspected if I can do this, it would be through cookies.
Perhaps a little more work, I could create a page which calls each page, then I could acquire the URLs from my history, but my browser would crash for the # of URLs I'm extracting.
any means I could gather the end URL of this link?
I am using zipforge.net to archive files in a small backup program I am creating. Everything works fine however if I try to archive a large number of files the process of zipping them gets slower the further along in the job it gets.
Example: I have a directory that contains a little over 100,000 files in it. Each file is only about 200k of text. When I use the zipforge zip class it starts zip'ing very quickly but as it gets about 40% of the way through the directory it starts to slow down... at about 60% its working at a snails pace.
Memory usage for my solution also goes up proportionate to the archive file size as it grows. Currently it takes around 26hours to backup this directory which only contains 4 gigs worth of information.
If I use a program like winzip I can zip the folder in less than an hour. I am thinking there has to be a way to write to the end of the zip file without having to open it every time or without keeping it open. My backup software scans the specified folder and writes each file path and name into a text file. Then it reads the text file line by line and passes the path + file info to the zipforge addfile().
I know this is probably a stupid question. I am converting a huge string to a integer, it is not working.....saying the number is too large to handle. It is only a 10k character string.I figured this would be fine because 2^16 power is 18446744073709551616.
I am wondering on the complexity and advisability of translating hard-coded string values in my VB apps. I have used the GNU gettext library for C apps, but going through creating a custom wrapper to interop for my VB libraries seems redundant. I know that there is the option (which I have used) of doing satellite assemblies for localizing the form, but for the strings that I have coded this does not seem to work. how to use the power of .NET to extra the strings from my code, put them in a string table and have separate string tables be called based on culture selected?
I have to export the data from the database to .txt file, I have the code below that does export it to .txt file but I'm having problems with this code because the data that I'm exporting is about 5 000000 records, it is quite slow and sometimes the pc can't handle it and stops the exporting.
Dim saveFile As New SaveFileDialog If saveFile.ShowDialog = Windows.Forms.DialogResult.OK Then command = New SqlCommand
In my application, every time a button is pressed a complex interface is built, it requires few seconds to be built.All works well till someone press the button too quickly and the application lag behind.Is there a way to read how manu times a button has been pressed so I can jump to build the last interface number equivalet to the sum of the last few click avaoind to try to build the interfaces in the middle.
If you are working on a large record in database. How you manage to use the INSERT,,UPDATE? I mean when selecting a record base on two tables or more and those tables consist of 20 columns it hazard to put all those columns in one query.
[code]...
How to lessen the code without typing all those queries over and over again ?
I wrote last week about a problem with an MDI program that had a large number of forms (each with a large number of controls on it) that was "sluggish" in loading and in switching between the child forms.I've attached an example program in VS2008 (though the actual app is VB2010)Rather than show the hardware control application with all of the text fields, and picture boxes acting as indicators, I made a simple program to show the point. This is exaggerated as this just loads 2000 or so text boxes on a form. In the real app I have ~ 200 assorted controls per form of picture boxes, scroll bars, text boxes, labels etc. Also, there is a large full screen .jpeg as the back ground of each form. All are generated at run time and are placed on the form in the New call of each form. (as in the sample attached)main issue seems to be the methodology I use to switch between child forms. I make the current form .visible = false, and the next.visible = true. I have used this as it "keeps the place" on each page if the user has scrolled or is looking at one section of the form. When the next form .visible = true happens I see the controls added in a "machine gun" fashion instead of all at once.
We have a customer, who prints a large number of a batch job to a reporting service. When printing large batches of jobs, occasionally he would get a WebException from reporting services saying "The underlying connection was closed".What is the work around for this? Somebody added this portion in the code [code]It doesn't seem to fix the issue though. The customer still notices the Web Exception when she prints a large job to reporting service.
When large number of records in Database, it throws error "Operation has been canceled by the user" in vb.net. I want to retrieve records from DB2 and display the records in DataGridView in VB.net. If number of records is less it works fine. But if the database tabe has large number of records it throws error "Operation has been canceled by the user". [code]
I am developing a software with multi language support.. I've done localizing the controls. But there is problem localizing tool tip text for selected language.
I had tested this code: [URL] It works, but a Word application is opened and each new paragraph added using VB code is seen one by one(with a small delay). If I want to open and write something using VB, what is the fastest way ? I do not want to view the changes made on word document live. I want to save the document. So will oWord.Visible = False makes it fast?
I have a large financial application which I am migrating to VB.NETIt has two main components: charting and financial statements.I want to know if it is possible (and how) to create a main exe, and then two separate projects for the two components (as dll's?).
I am currently helping to write a Visual Basics program that was originally writing with access.The Original Access program has been used and modified over the past 5 years, During that time the database has gotten pretty big.The problem I am having is If I add the entire database to my data sources it creates data tables for every Table and Stored procedure even when they are not currently used in the program resulting in a 20+ minute build time just to debug.I am currently only adding Tables and Stored Procedures as i need them, so its not that much of a problem now, but as I continue to work and add tables the build time is going to go back up, and Id hate to have to wait 20+ minutes to test a small tweak I made.
I have a multi-lined string message that needs to be added to the Resources.resx file of the project. Currently I'm achieving this some thing like this MessageBox(My.Resources.MyMsg1 & vbNewLine & My.Resources.MyMsg2 ). This works.However I'd like to have the entire message in one resource string rather than adding two resources strings to the Resources.resx file.I've tried using' but no luck..message displays as "My message.Rest of the message".I've also tried manually adding a new line in the Resources.resx file. ( by doing "My message.<Shift+Enter>Rest of the message" But message is adding an additional space before the message in the second line.
I 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.
