Working on converting an application from VB6 to .net.
After conversion I got the following error:
A custom wrapper for this COM component has been installed on your machine after you added this reference. This wrapper may provide additional cpabilities not offered by the auto-generated wrapper currently in use
it asked if I wanted to update it so I did, now I get several errors
'MSComctlib.Button' add one to you project.
I am not sure exactly what this is telling me to do...
Help!
[edit] never mind. Figured out what happened... boy this is fun....

Yeah, VB6 and VB.NET are so vastly different as to pretty much require you to scrap your VB^ project and rewrite it from scratch. At least that's what I recommend doing.
The conversion wizard was not meant to convert VB6 to VB.NET and leave the resulting code in place and treated as the prodiction app. It was meant to convert your project to the point where you can start to rewrite the app piece-by-piece, releasing incemental version, without having to rewrite the entire app all at once.

that is what I am finding. For the most part it is not too bad. The biggies I have to change are my use of control arrays (what a pain), the popup menu's (after the control arrays) and a bunch of work with a printer which you can't do in .net. like you could in 6
I would say that is probably 90% clean convert other than that, probably because I tried to follow good practices when I wrote it originally (10+ years ago)... at least I would like to think so...

Hello Champs,
I hope you're laughing at my question and have plenty of solutions right on your fingertips  What might be important to know is that I'm using the German Version of Vista.
In my application, the line
Dim drv as DriveInfo
For Each di As DirectoryInfo In drv.RootDirectory.GetDirectories("*", SearchOption.TopDirectoryOnly)
...(code)
Nextreturns an array of subdirectories (just as it's supposed to ), which obviously contains
a) all the hidden directories
b) several directories with their English AND their German names (i.a. "Programme" AND "Program Files")
In the end I have 18 directories counted instead of 12 which I can see in the explorer. Filtering them by names in the GetDirectories filter option doesn't make a lot of sense, right?
But how can I restrict my array to the directories which are visible in the Explorer 
Thanks for helping ![Rose | [Rose]](https://codeproject.freetls.fastly.net/script/Forums/Images/rose.gif) ,

Hi,
I don't think there is any support for mimicking Explorer; anyway, the number of files/folder shown by Explorer depends on several settings.
FWIW: starting .NET 4.0 there are new directory methods that enumerate files/folders one by one rather than building an array first.

Thanks, Luc. Unfortunately the app is supposed to run under W2K, so I'm afraid I have to limit my expectations regarding .NET4.0 
But I found a workaround (posted here for others):
Dim drv as DriveInfo
For Each di As DirectoryInfo In drv.RootDirectory.GetDirectories("*", SearchOption.TopDirectoryOnly)
If Not di.Attributes And FileAttributes.Hidden Then
...(code)
End If
NextAs a result I have the right count and no recycle-bin (i.e. the other unwanted stuff). The only thing still bothering is that I have the Englisch folder names for "Users" (instead of "Benutzer") and "Program Files" (instead of "Programme"). If anyone has an idea how to solve that - maybe it has to do with the 'cultures' in VS, which I didn't explore yet - I'd appreciate. But since it's not really important (even most of the users know some English ) and only relevant for the root drive, I might just skip the issue as well

I want to plot a number of different cells from a sheet in to a bar chart. The cells may lie anywhere in the sheet (not necessarily in one row or column).
I have an array that stores the address of these cells.
This is what I am doing to plot the bar chart in VBA
Firstly, I make a string of the cell addresses (for eg DataSheet!$B$4, DataSheet!$B$3, DataSheet!$E$7, DataSheet!$G$11, DataSheet!$J$1)
Then pass this string to the chart for plotting
ActiveChart.SeriesCollection.Add Source:=Range(Str)
This works fine till the number of data points are less. But when the datapoints are large, the string grows bigger in size and the above plot function fails.
Is there nay other way I can accomplish this?
Thanks,
GJ

Hi,
I trust there are other ways, I am not familiar with them though.
Here is what you could do right away:
- drop the dollar signs
- drop the spaces
- rename the sheet to something that is much shorter.
DataSheet!$B$4, DataSheet!$B$3, DataSheet!$E$7, DataSheet!$G$11, DataSheet!$J$1
X!B4,X!B3,X!E7,X!G11,X!J1

Hi GJ,
I'm not quite sure if I exactly understood what you're doing, but it seems to me as if you're doubling up unnecessarily and just make the string longer and longer. Maybe you wanna try adding your cells as single elements in a loop, like
For i = 1 to x '(= Number of Series)
ActiveChart.SeriesCollection.Add Source:=Range("DataSheet!$B$4")
ActiveChart.SeriesCollection.Add Source:=Range("DataSheet!$B$3")
....
Next
If you really add each cell manually, this is a big challenge anyway.
Hope it helps,
Mick

Thanks Mick for you reply. But wouldn't this create a lot of data series (one for each point)? I want all the points to be in one data series.
Thanks,
GJ

IC. You would then pass an array of strings to the values collection, e.g.
ActiveChart.SeriesCollection(index).Values = Array(Range("Sheet1!$A$29"), Range("Sheet1!$B$33"), Range("Sheet1!$C$35"), Range("Sheet1!$C$30"))But this you only need if your Ranges are spread over your sheet.
If you follow Daves advice and order them blockwise (in a hidden sheet), you can simply add the resulting (ordered) range like e.g.
ActiveChart.SeriesCollection.Add Source:=Range(Worksheets("Sheet1").Range("C5:T5"))

Write up some code to copy the values to a hidden sheet, in a nice ordered fashion, then supply that hidden range of values to the chart.

I use ie object to navigate in html page.
Now in the a page of site here is a table with a button...
When the user cklick on button the table is filled with a new data.
I think... the Button clcik send a notice to a Data Server where are stored the recordset(?!) and retrive a string with data to insert in table...
My question and dubt are:
Is possible to intercept the string of data before the code insert into table?
Is possible to intercept the source of data?
the page of site are all in ASP.
Tks.

It might be possible with something like greaseMonkey.

I don't understand what you mean by that.

What error?

VB6 and Vista is like smoked liver and ice cream. The combination could work but no-one would ever suggest trying it.

SendKeys is notoriously unreliable to use. I would not be using it in a production application.
Either way, IIRC, the problem only showed up on the Beta versions of Vista. Well, that's the last time I heard of the problem anyway.
You can find a piece of code to replace the SendKeys call here[^].

Hi, I'm using Linq To SQL.
I've run this code :
Dim TmpDto = CallByName(TmpSrv, hfSelectedNode.Value, CallType.Get)
that returns a System.Data.Linq.Table(Of [A DB Table])
I need to filter this table with 'Where', the extension method, and when I used callByName, it said "The public method Where was not found"
As you has undrestood, I don't know table name in compile time, so I need to call it runtime.
How can I do it?
Best wishes

You'll have to post the code for the function you're trying to call.
BTW: CallByName is VERY slow. Using it is considered bad practice in a production application because of it's performance issues.

I have created a MDI application with many forms and created a few custom controls that are needed for the data. They are extended off of UserControls, most are composite controls, but not all.
When a user is on Form1, and a "Standard" text box has focus, the users switches to Form2 to check something, then back to Form1, The "Standard" text box still has focus when they return.
When using my "Custom" text box,(a UserControl with a text box droped on to it in the Designer) when the Custom text box has focus, when the user switches to the other form, and then back, some other field (usually lowest tabindex) ends up with the focus.
How do I setup my UserControl so that focus ends up back in it when our form looses and regains focus.
I have a skeleton program with the same error with none of my custom code in it that I can upload or email to you if it helps.
Its most likely something stupid, but I cant find it.

The problem is that when the user switches away from the initial form, the first event to fire will be that the form has gotten focus, after which the form will automatically move focus to the control with the lowest tab number, or to the control that you explicitly tell it to. So if the last control to have focus should always get the focus back, you need to monitor which control (for example your textbox) has focus at any time (for example by its index or tab number).
Then you can just set focus to that control when focus is brought back to the form.
In other words, the problem hasn't anything to do with your usercontrol.
My advice is free, and you may get what you paid for.

I agree that that is what is happening with my usercontrols, But when the focus starts out in a standard text box, that is not what is occurring. In the standard text boxes (or any other windows "standard" controls). when returning to the first form, the focus returns to where it was when we left the form automatically.
For example, a form with three controls, two textboxes, TabIndex 1 and 3, and my UserControl tab index 2
Tab Index 1 -> Jump off and return -> Tab Index 1 (as expected)
Tab Index 2 -> Jump off and return -> Tab Index 1 (the questionable one)
Tab Index 3 -> Jump off and return -> Tab Index 3 (doing what I want my control to do)
Also I have tried code to monitor what the last selected control was, and to reset it using OnEnter and OnLeave functions, but Even though it was doing LastControl.Focus() on the correct LastControl the focus was still ending up back at TabIndex 0 as if something else in the application was forcing it to go there for some reason. But even with every other reference to "Focus" in my code commented out, it still kept going back to 0. (Also in my basic test case that I created with out any other code in it, just standard controls and the absolutely fewest lines of code to make the forms show up.
Does anyone have an example of tracking the last control used? I could easily be doing something wrong, but with the time I have spent on this, I don't think so.
