Hi,
I use Inet control to download a file (HTTP)
in the StateChanged event to get data using : GetChunk
the problem is that i want to display a progress bar so I need to know the total
length of the file .. I use something like this:
<br />
If State = 8 Then<br />
n=val(Inet.GetHeader("Content-length"))<br />
end if<br />
it works but some times i get an error .. should I call GetHeader when the state is 12 not 8?
what is the difference ? I read MSDN but wasn't clear in this point..

This is my Problem:
I have two projects open.
Project #1 is the server App. It loads a list of Dll from a Configuration file.
I load a DLL into my application on startup and can call procedures from it.
I want to be able to have the Server App unload the Dll.
Project #2
I will modify the DLL ,Save it , and then have the Server App reload the Dll and use it.
I can't seem to unload a DLL without closing the Server app.
I have everything else working fine.
Anyone have any ideas?

This is a problem that comes up a lot. The short answer is: you can't. The long answer is that this is managed code - the CLR manages everything for you and there's very little you can do about it. As far as "Project #2" goes, you should look at System.CodeDOM and the System.Reflection.Emit namespaces. Using those you could "easily" read-in a template "DLL", modified it, then emit an assembly either in memory (loaded into the current AppDomain) or in memory AND on disk (thus saving it for future use). Several libraries - even the .NET Framework use this technique for non-persisted assemblies, but persisting it is as simple as using a different Enum value in the very same method!
Good luck!

Thanks for your assistant.
I will research the namespaces you suggested.
This is my overall project.
I want to create a server app that runs all the time.
I want the server to load plugins and run them on set intervals and on specified events.
I wanted to create the plugins in VS.net and copy the dll to the plugin location.
I also have researched the CodeDom namespace and can actually create the plugins from the Server app and compile/load/Run them but for this to function correctly, I should give the end user the ability to modify the source code of the plugin and recompile/load/run without restarting the server app.
If the System.Reflection.Emit will create dynamic assemblies in memory then this may work better than saving them to a dll and loading them for each use.
This is my attempt at creating an app with scripting embedded in it.
Thanks again for your help

Actually, if scripting capabilities are what you're looking for, this issue is already solved. You can use the assembly emit stuff to parse, compile, and load script. There are even ways to interop with Windows Script, allowing any scripted language (JScript, VBScript, PerlScript, etc.) to work, so long as you supply the script engine with the objects, methods, properties, and events it can walk and use. See MSDN for more information.

I tried to modify my code to generate the assembly in memory
instead of creating the dll on disk. and I get an error.
An unhandled exception of type
'System.IO.FileNotFoundException' occurred in mscorlib.dll
Additional information: Could not find file "C:\DOCUME~1\GDUDLE~1.MBI\LOCALS~1\Temp\cdqmv_u2.dll".
Unhandled Exception: System.IO.FileNotFoundException: Could not find file "C:\DOCUME~1\GDUDLE~1.MBI\LOCALS~1\Temp\cdqmv_u2.dll".
File name: "C:\DOCUME~1\GDUDLE~1.MBI\LOCALS~1\Temp\cdqmv_u2.dll"
does this mean it is still creating and loading from the disk? The filename it is displaying changes each time I run it so I assume it is a temp file.

I need Help! I'm trying to convert this script to VB.Net but its in java and I don't fully understand java to well.
var logQuery=new ActiveXObject("MSUtil.LogQuery"); <br />
var recordSet=logQuery.Execute("SELECT * FROM <1>"); <br />
<br />
for(; !recordSet.atEnd(); recordSet.moveNext()) <br />
{ <br />
var record=recordSet.getRecord(); <br />
for(var col=0; col<recordSet.getColumnCount(); col++) <br />
{ <br />
if(record.isNull(col)) <br />
WScript.Echo("NULL"); <br />
else <br />
WScript.Echo(record.getValue(col)); <br />
} <br />
}
ok I tryed this but:
'ExecuteBatch' is not a member of 'System.Array'.
Dim szQuery As String = szSelectClause & szAS & szLogFileDir & szLogFiles & szWhere & HackCond & szGrouped<br />
Dim test3 As MSUtil.COMIISW3CInputContextClass<br />
Dim test2 As MSUtil.COMCSVOutputContextClass<br />
Dim g_LogParser As MSUtil.LogQueryClass() <br />
Dim recordSet As MSUtil.ILogRecordset = g_LogParser.Execute(szQuery, test3, test2)<br />

Hello,
I'm using vb.net . I want to make a window

there isnt a zorder like in vb6 ,but SendtoBack works fine, i just placed a listview over the top of a richtextbox then on a command button did the following
ListView1.SendToBack()
and the listview got sent to the back ( behind the richtextbox )

Hi,
I have designed a usercontrol with a label-, a textbox- and a button-control. To accelarate the design-time I have tried to bring some of their properties on top of the property-editor, f.e. like this
dim fLV as boolean
<br />
<Category("Basic Properties Label")> _<br />
Public Property LabelVisible() As Boolean<br />
Get<br />
Return fLV<br />
End Get<br />
Set(ByVal Value As Boolean)<br />
fLV = Value<br />
Label1.Visible = fLV<br />
End Set<br />
End Property<br />
After that I have created a form with a tab-control and about 4 sheet. When I insert my new control on page1-3, then activate page 4 and run then program, all of my self-created controls are no longer visible. This effect is shown even at design-time after an execution of my program.
I'm looking for a solution , until now, I haven't found any. Maybe you have one?!

Hello,
I tried to fill combobox with the property :
ComboBox1.DataSource = SelectByName() 'return a datatable
ComboBox1.DisplayMember = "NOTES_TEXT"
ComboBox1.ValueMember = "ID_NOTES"
And it works well.. But when I try to do this on the same form :
ComboBox1.DataSource = SelectAllName() 'return a datatable
ComboBox1.DisplayMember = "NOTES_TEXT"
ComboBox1.ValueMember = "ID_NOTES"
ComboBox2.DataSource = SelectAllNotes() 'return a datatable
ComboBox2.DisplayMember = "NOTES_TEXT"
ComboBox2.ValueMember = "ID_NOTES"
The combobox are binding but I have two times the same value : the combobox1 have de value (data) of the combobox2 !! If I do that on a different form, it's work !!
Why.. it's two different DataSource..?! If it's because there is two times the same DisplayMember and ValueMember what I have to do ??
Thanks a lot for your answer..

Hi,
I'm a VC++ programmer, and I need now to develop some ActiveX controls in Visual Basic 6.0 for a client. Could you point some good book about this issue ? ( well and another good book to learn Visual Basic  ).
Thanks in advance

From where i can download the Source code of that book. (for Free) 
|
|
|
|
|
To download the source code for examples of this book go to
www.sybex.com[^]
and search for the title..You'll find a link in the page that directs you where to download code on the CD.
I'm not sure if the book itself is available online.

Hi,
i have 2 dynamic rectangleF and one string.
Now i want to use the substring to split the text in 2 parts.
If the first rectangle is full, then use the second one.
Is there any way to draw a string inside a polygon ?
If yes, i would use that..... but at the moment i can only fill text
in rectangleF with Drawing.String.
Or know someone how i can see the text.length for the first rectangleF (max. length),
so that i can use substring on it.
Hope someone can help

I want to load a data grid with data in an XML file. I know i can do this with the ReadXML method of a dataset and then set the DataSource of the grid = to the dataset. But how do I take all the data in the grid and get it back into a dataset so I can save it back to XML format? Also how can you set the column widths for each column and do things like center the column headings and things like that?
|

When you databind your datagrid with a dataset, you are in fact setting up a "relationship" between the 2 objects. The changes done in the grid will be reflected to the dataset, so all you need to do is retain the dataset in memory.

Hello,
All I am trying to do is run simple programs that I learn from a book
every time I "Start without Debugging" it gives me a messageBox with "there were build erors"
Now this seems to happen when I rename the ".vb" file and rename the "Module" (I am in the beggining of the book and were are just on simple modules). Also under the build error 'Task List' it says "Sub Main was not found in 'ConsoleApplication1.Module1
Help. I am a rookie and i need help fast

It seems like you need to set the startup object in the project properties. TO access the project properties, you can either:
1. Click Project on the Menu Bar and select Properties, or
2. Right-click on your project in the Solution Explorer and select properties
On your project property dialog, you will see a combo box labelled "Startup Object". Navigate your combo box and select a startup object, which is usually a Sub Main method.

hi.. i have a problem regarding change some status frquently.
i m aorking a application of Port updateing and ports are updateing very-very frequently...i m collecting this information thru a event of a DLL. ..and when-ever status of any port will change the event genrates and give me the port no with the current status...then i should have run a function to changethe status....
now the problem is how can i update this information...thru therading or any easy way is for that? i m using vb.net and vb6...
regards
anand

vb6 is not strong in multithreading
but you can use an ActiveX EXE to do multithreading (but better to use APIs if you want some synchronization)
in .NET multithreading is supported.
