Hello,
I am having difficulties with display text coming up blank when running the complied code on Windows XP test workstation. I have an existing application is displaying blank when a user is prompt the message.
The same executable works just fine development computer.
Example...
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
MessageBox.Show("Hello World !")
'msgbox.Form1("This is a Test using ..." & ControlChars.NewLine _
'& "MsgBox")
End Sub
Thank you

I just figured out the problem. The problem is with "Network Associates McShield" service. When I stop the service the Text is displayed properly from the MS VB.NET application. McAfee has a hot fix #9 to resolve this problem.
Thanks...

I´m trying to make an "administrative console style" application using
vb.net (an application with a visual layout as usual mmc console applications). I'm
using a main form with a SplitContainer. In the left SplitterPanel I have
a TreeView control, and my idea is to open "subforms" in the right side
SplitterPanel. This is easy to do with code like:
Dim frm As Form
frm = New subform
frm.TopLevel = False
Me.SplitterPanel1.Panel2.Controls.Add(frm)
frm.Show()
This works. The problem is when need to resize the main form. The
"subform" remains in the some original size. Can someone tell me how
to force the subform to resize ? Is there any better way to make
this "administrative console like" type of applications?
Thank you

You can play around with the form's Dock or Achor properties. Dock will 'stick' the form in Top/Bottom/Left/Right/Fill position in the panel. Achor let the panel resize the form according to which side you want to 'stick' it to.
Remember most if not all controls have these 2 properties too.

i have to send data packets (9 bytes each) to another terminal device. However due to the hardware design of the terminal device there has to be a pause of 26.3 milli secs between two data packets. in case the pause duration is not matched the device is unable to accept the data. please post a suitable code for delaying the com port output for this specified duration (26.3 m secs).

I don't know that you are going to achieve this with Windows and VB. The system timers exposed by the OS do not have the resolution you are looking for. In any case they are not guaranteed to pop exactly at the interval to which you have set them (very close yes - but not exact).
Is there any leeway in the packet timing to the terminal or is it a very old black box?
Seems to me that you may need a hardware interface between the computer and terminal to handle this problem.

hi steve thanx for replying. firstly answers to your querries - well the terminal device is a black box. the leeway that we can have in this pause if from 26.1 to 26.7 milli seconds.next i cannot go in for a hardware solution as the package i am making is a universal applicaion for some other blackboxes also which have different pauses between the data transmissions. i percieve three options, firstly i tried the "do while loop with a counter delay" that was working somwhere around this range but not exact 26.3,hence is not exactly suited. secondly, the inbuilt timer object is also not of much help as it is not accurate in this range. thirdly, i read about some kernel32 commands that may be used. can you just tell me if it can be of any use to me and how if yes? then can i embed some C++ counters or delays in vb. your help is greatly solicited also thanx anyway for replying the first time..

As stated in the article I quoted (my 2nd reply to your post) the Windows timers are not going to be as accurate as you need for this application.
No amount of application code in a high level language like VB, C, C++ etc... is going to do it for you. I think you'll need to create a device driver for your black box (essentially a new serial port driver) to handle the timing for you. This way the driver can operate at the kernel level and respond to interrupts rather than at the application level.

I found this article on The Code Project[^] which describes the Windows OS timing. Hope it helps.

I have a data grid which shows the clients that I have in a database, then when I press the button to add a new client, it is successful, however when I get redirected back to the datagrid the client that I just entered doesn't show up as the last client. In order to make it work i have to make a refresh button, but I want it done automatically.Any ideas ?
I appreciate your help
thanks

Are you using Winform or Web Form?
Anywayz I think you first add client add code
then update your dataset
then refresh your dataset
then select data again.
Hope you will understand what i mean to say..

make an entry into your registry. e.g., ur path of program to be executed is c:\xx.exe,
> just goto start|run & type regedit
> follow the following dir
HKEY_LOCAL_MACHINE\SOFTWARE\MICROSOFT\WINDOWS\CURRENTVERSION\RUN
> make a string value on the right side say xx
> double click on xx entry and enter the path(say c:\xx.exe) of your appl in value textbox
> restart ur system & check it

My VB app uses a form to input the report parameters and call a second form containing the crystal object with the formated report with subreports, this works fine until the report form is closed and the user enters a second set of parameters in the parameter form and calls the report form again, The code that logs the subreports into the database fails stating "Object reference not set to an instance of an object"
For index = 0 To objReport.ReportDefinition.Sections.Count - 1
For intCounter = 0 To _
objReport.ReportDefinition.Sections(index).ReportObjects.Count - 1
With objReport.ReportDefinition.Sections(index)
If .ReportObjects(intCounter).Kind = _
CrystalDecisions.Shared.ReportObjectKind.SubreportObject Then
mySubReportObject = CType(.ReportObjects(intCounter), CrystalDecisions.CrystalReports.Engine.SubreportObject)
mySubRepDoc = mySubReportObject.OpenSubreport(mySubReportObject.SubreportName)
For intCounter1 = 0 To mySubRepDoc.Database.Tables.Count - 1
mySubRepDoc.Database.Tables(intCounter1).ApplyLogOnInfo(ConInfo) 'sp;
mySubRepDoc.Database.Tables(intCounter1).ApplyLogOnInfo(ConInfo)
Next
End If
End With
Next
Next
the code loops thru the sections to find subreports and logs them into the DB but only works on first execution.
Any suggestions?

Hi to all,
I have a question for anyone who can help me on the subject custom controls in design time.
What i want to achieve is following:
how can you create a method/function in the propertypage in the visual studio IDE just klike the ones you have with like for example the SQLDataAdapter (in the help/description field some links appear with behind that some wizard functionality). Anyone any ide how to do that? I don't seem to find any good example anywhere.
Another thing i wanna do (i know i ask a lot, but it aren't common things in my eyes so that why i post everything here  ) is to add custom section in the app.config during design time ( so not to the compiled app.exe.config !!!!!) What is the easiest way to do such a thing, i mena can i just use the executing aasembly name? or is there a catch.
For thos who can help me, many thanks in advance.

OCX files and ActiveX dlls need to be registered.
Use the regsrv32.exe command line, or use the package and deployment tool to build a release for your setup that automatically registers all the dependencies.
