View 2 RepliesIn my VS2010 VB project I have a lot of external references to DLLs, to the point that organization has become a major headache and I'm wondering if I am going about it the wrong way. My assembly references include common redistributables (SQL Server Compact 3.5 SP1, ReportViewer 2010 SP1, DataVisualization, as well as some useful 3rd party dlls from CodeProject and CodePlex.
Currently, I am copying each DLL into a 1st level folder (/dll_lib) under my named project folder (under the solution folder), and adding the reference from that path. However, I see that Visual Studio copies the DLLs to various other locations (/bin/debug or /bin/release) in my project when I build the project or solution, and some of the 3rd party DLLs come with instructions to copy them manually to /bin.
What is the "best practice" for where to put the DLLs? Can I just put all of them under /bin and let the build event copy to /bin/debug or /bin/release as required? Should I try to force a single reference path for the dlls in the project output?
With several forms of mine, I occasionally run into the following issue: I edit the form using the designer (Visual Studio 2008, Windows Forms, .NET 2.0, VB.NET) to add components, only to find out later that some minor adjustments were made (e.g. the form's size is suddenly changed by a few pixels), and controls get deleted. This happens silently — event-handling methods automatically have their Handles suffix removed, too, so they never get called, and there's no compiler error. I only notice much later or not at all, because I'm working on a different area in the form.
As an example, I have a form with a SplitContainer containing an Infragistics UltraListView to the left, and an UltraTabControl to the right. I added a new tab, and controls within, and they worked fine. I later on found out that the list view's scrollbar was suddenly invisible, due to its size being off, and at least one control was removed from a different tab that I hadn't been working on.
Is this a known issue with the WinForms Designer, or with Infragistics? I use version control, of course, so I can compare the changes and merge the deleted code back in, but it's a tedious process that shouldn't be necessary. Are there ways to avoid this? Is there a good reason for this to occur?
One clue is that the control that was removed may have code (such as a Load event handler) that expects to be run in run time, not design time, and may be throwing an exception. Could this cause Visual Studio to remove the control?
If I build a Windows Forms project in Visual Studio 2008, and start it with a Sub Main instead of a form, and for the time being, don't show any forms, is it considered a Console application? Will console.writeline work?

I'm trying to build a setup program using the built-in Visual Studio Installer. I'm using VS 2010 and working on VB.NET.For the most basic kind of program, I have an EXE file which works on a XML file (the XML file is treated like a database). So on a Windows 7 platform with UAC enabled, the best deployment is to install the EXE file in the Program Files folder, and the XML file in the application data folder, for security purposes of Windows. (Windows, now, does not allow creating/writing files inside the Program Files folder unless your application is running with administrative privileges).
So I have added VS Installer to my current project and have opened its File System Editor. So to create the above layout, I've added Primary Output to the Application Folder. Then I've added its shortcut to the User Desktop.Now I need to place my XML file to the application data folder. VS Installer gives the option of User's Application Data Folder, which is the %appdata% folder in the environment table. I need to access the All Users' Application Data Folder.
1) How do I access the All Users' Application Data Folder over here?
2) I tried using the User's Application Data Folder. It doesn't work. It doesn't create any folder in the %appdata% (e.g. C:UsersFarazAppDataRoaming). I tried to play around with various properties, like AlwaysCreate which is supposed to create a folder obligatorily. It doesn't create anything.
Trying to get it to behave like C#, where there is a Program class with a static Main method.However, in the project properties, I cannot set Program.vb to be the startup object, only the forms (it is a forms application).
View 2 RepliesI hope I got all that in this question title. Let me explain. We are starting on small desktop app that will snowball into a big app with many forms. The database is SQL Server. It will have classic stored procs/functions performing classic CRUD functions. Given a table or stored proc in SQL Server what is the quickest way to create a form with all the hooks to maintain a table.
For e.g. lets assume I have table like this (most code below is pseudo code)
Table Employee
{
Name varchar(30)
DOB Datetime
Address varchar(100)
}
From this as source I want to create my Target which is form with 3 labels and 3 textboxes with add delete modify buttons (or OK button to add if not exists or modify if exists)

The code generation tool or technique that will be used should generate the correct db hooks (create SQL parameters, SqlCommand, execute sql.. basic try catch etc. Is there any open source tool to do this ? Some trick or templated approach via VS 2010 ? Worst case any third party tool ?

View 3 RepliesI am programming in VB9 WPF and Blend 3. I was working on a program in Blend 3; I can work on all my forms and everything runs fine in Blend, but when I opened it in VS the WFP forms would not display (I have five of them in my program and they all have the same problem in Visual Studio.), but I can run the program in VS, see the forms in run mode, and work on the code behind with no problem. I can't determine what is causing the WPF forms error in VS. It appears I have a "ResourceDictionary_4 error, but I cannot locate that dictionary in either Visual Studio or Blend. I even tried searching my entire computer and can't find any trace of it. Are there any ideas as to how do I solve this problem? The error messages I am getting are:

I am trying to make a UI that has a few forms / panels, each for a different "Tab" in the program.
I am guessing that the way to do this is using panels and code like:
Panel1.Visible = False
Panel2.Visible = False
Panel3.Visible = False
Panel4.Visible = True
Would I be correct in assuming that this is the best way to go? (I don't want lots of popup forms in the program, looking for the most streamlined way to go).
Also, if this is the correct way to go how would I go about hiding each panel in the IDE so that I can work on each one seperately using the designer view?
Here is the best example application I can think to use: [URL] Each of the tabs (Proxies, Harvester etc) has an image as the tab (Which I can't find an option to do with TabControl and then displays the container / panel below it
A Dialog that is added to a Windows Forms project comes with two buttons (OK and Cancel) and Click event subroutines for each. The subroutines close the Dialog with different DialogResult enumerations. Here's the code in the one for Cancel: Me.DialogResult = System.Windows.Forms.DialogResult.Cancel Me.Close() But either statement (changing DialogResult to an enumeration other than Null or Close), by itself, will close the Dialog as well. (Try commenting out one and then the other to prove it to yourself.) Here's the question: Why both? Why not just one or the other?
View 1 RepliesToday I noticed that Visual Studio 2008 always treats a file as if it was a component or a form if this file contains a definition of one.This means that it always opens the designer by default. I think this behavior is very annoying, because a file containing a class that derives from form or control does not have to be an actual form or control and I want to edit the source by default.
View 2 RepliesI'm just wondering, what is the best way to load and unload forms with visual studio 2005. In VB6, I used to use the following at a button click, for example.

If I look at some classes in the framework, using reflector, I can see that forms and user controls are made private and nested into a parent class.For instance, I have a control which makes use of pop-up form that is specific to that control.At the moment, I make the pop-up form friend accessible.If I wanted to do it the framework way, I'd make it private and nest it into the control class.If I do this, however, I can no longer use the ide to design the form and I get errors when I try to compile.
View 1 RepliesI can launch a program from inside my program and embedded it in my program using a Visual Basic Control such as a Panel. That works well if you launch say NotePad or Calculator.However, If I want to launch a program that uses MULTIPLE forms... all that gets embedded is the Main Form... All the other forms are floating on the desktop nonconstrained... So If I minimize my program the other forms are still shown.So what I am attempting to do is to get ALL the Forms from the external program embedded into their own objects on my form.Have pieced together a program from a couple of program samples that I have seen across the internet... Here's the code so far:[code]The Main form for the program that I am attempting to embed is 384 x 347 in size.Panel1 is a Panel Control on my Main Form."MyProgram.exe" is a program that I have written myself.I have looked at Spy++ for Visual Studio 2003 and it is able to identify ALL the forms from my program.My question is how do I embed ALL the forms from my external program in the NEW Program?
View 8 RepliesIs there any predefined property by which I can set the DisplayFormat/DisplayStyle of a textbox? Suppose I want a textbox to hold the actual value 888888888888.88 and show it formatted as 888,888,888,888.88. In short it should hold 'Double' data type value and show it with thousand separators and decimal places upto two digits. If text is cleared from the textbox, it should have 0 as value and 0.00 as displayed value. Also the number of digits in the textbox may vary accordingly. So how can it be done?

View 1 RepliesThe environment will not create a resource file for a newly created Windows Forms Application. When I add a button Visual Studio displays a dialog "File Exist". That'sall, plus an OK button. There is no file name or the file name is in unreadable characters.The dialog comes from Visual Studio because the title is "Microsoft Visual Studio".There is no resource file so it must be that the resource file cannot be created.I uninstalled and reinstalled Visual Studio 2008. It did not change anything.I believe the problem was caused by opening the same project rapidly twice on an i7 laptop. I have done this unintentionally before and I can testify that unpredictable
View 2 RepliesAt present I have wrote an application (in-house CRM, vb .net 2010) which allows me to send emails under the selected customer & I categorised these emails.As these are categorised I can return data to display email history in my program by using search criteria:
Dim oMail As Outlook.MAPIFolder = oNS.GetDefaultFolder(Outlook.OlDefaultFolders.olFolderSentMail)
Dim sSearch As String
sSearch = "[Categories] = '" + "[" + tAccount.Text.Trim + "]" + "(" + tShipTo.Text.Trim + ")'"
Dim oItems As Outlook.Items = oMail.Items.Restrict(sSearch)
However the limitation to the above is it only looks at sent items & no other folder.My ideal solution would be to display all email correspondence for a certain contact.

How can i display what version of windows i am running? for example.i have a button if i click it the label on my form will display the version of windows.
Long story short I made a form in VB.Net project which involves lots of icons and images. My problem is when I build my project, and then go back to that form, suddenly errors showed up.
The errors says : "The type 'MyProject.MyResources.Resources' has no property named 'myicon'". Just to be clear, it worked fine before I did the build, and it happened to every single images I have on Resource.
When I chose "Ignore and Continue" all of the images I used are gone. I tried to googled it, some says to delete my .exe file on Application/Bin/Debug folder, which is working. But this issue has been some kind of an annoying one, since it happens again every single time I build.
Is it easier to print a VB.net windows form in Visual Studio 2010?
I have been struggling with this - the PrintForm utility in the Powerpack only prints the displayed portion of the current form.
I spent a lot of time creating a process which loops through each control on my form, converts to a bitmap, and drops it on the print document, only to finally discover that the RichTextBox control (which I used extensively) does not include a functional DrawToBitmap method.
I have already researched various ways of managing this, but if VS2010 will do it without jumping through the hoops then I'll spring for it like the sucker I am.
I can do this in Access and VB6, I believe, so I don't think this is an unreasonable expectation.
i have installed visual studio 2010 32 bit on my new computer which have windows 7 64 bit. Everything seems ok. But now I try to learn how to draw some spheres with movement. I have tried to install openGL2 but it does not work or said that it does not fit with 64 bit, or it works only with VC.
Could any one, please, give me a short introduction to install and use open GL in vb.net 2010 installed on windows 7 64 bits ?
What I have is on my form there are several text boxes. These text boxes are for user input and attached to each text box is a Private Sub txtBox1_KeyPress function. In that function I have some validation code to check that the user is inputing only what I want them to. And if it doesnt it will pop up a message box telling them so, then it is supposed to clear the text box so the user can try again. But no matter what I try, the text box does not clear it still keeps the last character typed (the invalid one).
Here is the code for one of the text boxes.
Private Sub txtLanIp_KeyPress(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyPressEventArgs) Handles txtLanIp.KeyPress
Dim strEmpty As String = ""
If Char.IsDigit(e.KeyChar) = True Or Char.IsPunctuation(e.KeyChar) = True Or Char.IsControl(e.KeyChar) = True Then
'do nothing
[code]....
The commented methods at the bottom are some of the other things ive tried to make this work. The txtLanIp.text.clear() is what ive tried from the beginning. I have also tried setting the text to "", I even created an empty string and set the .Text value to it but no matter what it wont remove that character. I have also tried various trim(), len(), Select() functions, most either give me an 'index out of range error', a 'length cannot be less than zero' error or a general ExceptionOutOfBounds error. I am just tearing my hair out as to why the simple way doesnt work, there is no logical reason why and it gives no error it just doesn't clear the box.
I have also tried moving the validation to a _LostFocus but e.KeyChar isnt a valid method or property for that declaration, which doesn't surprise me but I wanted to try everything.I dont see how it would matter in this case but I am running Windows XP Pro SP3, though I also see the same behavior in Windows 7 64 bit ultimate sp1 and windows 7 64 bit pro.
