Unable To Use ScaleHeight And ScaleWidth
Jul 25, 2011
I dug out some ancient VB4 code I still have. There use to be properties known as ScaleHeight and ScaleWidth. What happened to these properties? These properties were great for knowing the interior size of a component since ScaleHeight and ScaleWidth were not always the same as Height and Width of the component.
Since they seem to no longer exist, how do I find the maximum interior size of a component within another component within a form. I want to set the size of a component, mainly Tab Pages, to fill the interior of a form while staying inside the form. Then inside the Tab Pages, I would like to know the maximum width and height of a picture box without its dimensions actually going outside the interior size of the Tab Page.

I am trying to do the following...
VB
TextBox1.Left = 15
Me.Width = TextBox1.Right + 15
But the padding (of 15) is not the same on both sides. It seems like I need to be dealing with the VB6 equivalent of ScaleWidth.

I have a form that is first displayed as 425 x 66. When you press a button, the form expands to 425 x 398 and a message appears (a label prooperty) with the text: Processing Files. When the files are finished prosessing, a listbox appears and summarizes which records were added to the database.
The label begins as Not Visible. After I change the size of the form, I change the label property to Visible.
This used to work, but now, for some reason, the text simply doesn't appear.
I tried changing the lblproperty to Visible at startup but when I do this I get a black bar where my lable should appear.

I am developing a project that is dealing with CCTV camera made in china. I am provided by some DLLs from the company. Now i want to consume that dll into my application. I have tried default Visual studio's ADD REFERENCE features. then I have tried tlbimp.exe but it doesn't work.[URL]..I have search a lot about dll, some says "Check the dll header" and CLI Header. I opened this fine in notepad and I found only like "This will not work in DOS mode...". what to do next. Is there any way I can consume this file in .net.
I have already tried to add it as reference in Visual Studio 6.0 VB. even it says this is not a valis library.
Still dumpbin.exe is listing the function inside that dll.
I am confused about this scenario. Please guide me what to do with thi.

I am trying to create a Windows Forms control in VB.Net to wrap around a control in an old DLL I created in VC++ 6. I am trying to make a call to an API entry in my control:
Code:
<DllImport("myctrl.dll")> _
Protected Shared Function InitMyControl() As Boolean
End Function
However, when I add a call to InitMyControl to my control's code and try to load the form on the test project, the following error shows up:
Quote:
Unable to load DLL 'myctrl.dll': The specified module could not be found. (Exception from HRESULT: 0x8007007E)
I have tried putting a copy of myctrl.dll into the Debug and Release folders of both the control library and the test project, but I continue to get the error. I even copied it to my WindowsSystem32 folder, but still no luck.

I'm accessing a router using Webbrowser, to get some information from it.After logging into the main page, you click on a link which runs a script to display the info you want. I can do this OK in Firefox or Internet Explorer.In my VB program, having navigated successfully to the router's main page, I try to do this by using InvokeMember ("click") on the appropriate link element in the document and get this error in the script that runs:
"Unable to set the value of the property 'location': value is null or undefined".I don't know how to see the source code of this script, so any ideas on what the error may mean?When I hover over the link in Firefox, the status bar shows it as: javascript:MainFunction('./cgi-bin/v2x00.cgi?fid=168')

I was dabbling in pure Word VBA here and it occured to me that mixing the 'Set'-lessness of .NET with VBA might be confusing to programmers doing .NET Automation. Beyond that, the ambiguity example for Set here (near the bottom of the page) didn't seem to apply to the reason I had to correct the OPs code to include it. Further amusement came from reading some comments by one of the architects of VB here.

I have written an application that uses a DataGridView to display 740 rows, there are currently around 25 columns in my list. Have noticed in Win 7 64 bit that when I scroll the final row repeats, say 20 times, before it refreshes, its as if the display of my laptop cant keep up. Now this is a brand new Dell XPS i7 lappy with Radeon 4670 graphics so that should be fine.Also, the rows in the DGV seem to flicker a little, like it is constantly trying to refresh.My DGV works fine on Win XP.

Is there a good example on using C# with vb.net 2008 or above. I am looking for the simplest example. A class library I would be able to write with C# and use from vb.net. Probably a .dll I would imagine.
Could someone recommend some search strings for this forum I can try? I am looking for the shortest simplest example.

I'm trying to add a reference to the LAME MP3 encoder in my VB.Net (3.5) App.The DLL I'm using (lame_enc.dll v3.98.2) was downloaded from here:[URL]When I try to add the DLL reference to my project, I get an error:"A reference to C:\Lame_Enc.dll could not be added. make sure this file is accessible and that it is a valid assembly or COM component" I would just assume this was a corrupt download/similar but...
The archive passed an integrity test in WinRAR I tried re-downloading it JIC Next thought - the DLL is b0rked but...I've tried the SDK tools "genasm"(3.5) and "TlbExp"(2.0) and both say it's not a valid DLL.Previously when I've added non-.Net DLLs, VS has created an INTEROP Class for me. I'd ideally like to achieve similar with this DLL.

I have created reports using Crystal Reports in my asp.net application(vb). It was fine. But when I run it in another system, the report loading fails. So I modified my code like this.
sub Loadreport()
try
Dim sreport as new ReportDocument
sreport.Load(Server.MapPath("ClientList.rpt"))
[code]....
When the control comes to the line:-
sreport.Load(Server.MapPath("ClientList.rpt"))
it jumps to the catch block showing "Invalid Report path". But initially, the code was not showing any error. I haven't changed the path.
