Re: Resetting the DMM by transmitting *RST command through MSComm control error

Luc Pattyn27-Mar-09 21:47

Hi,

some guessing is required here.

your DMM probably wants some hardware handshaking (=data flow control), i.e. it needs you to set some control lines high or low, before it wants to listen to you (that would not explain the error conditions you mentioned);
or it wants you to not send stuff when it is not ready, as indicated by some control lines it is setting high or low.
I don't remember how handshaking and control lines work in Win32 or VB6; I do know for .NET

FYI: HyperTerminal by default chooses Hardware Handshake, Win32 does not. So try setting your COM port to hardware handshake.

I CANT HEAR YOU PROPERLY WHEN YOU SHOUT can you maybe talk a bit quieter.

Have you checked the various system/application error logs?
Have you checked the network stats for the dodgy client, is there high error rates?

Its a start.

You have to read the documentation on what these methods do (LTrim, Remove, SubString, ...). This is very simple string manipulation, and yes, Remove would be the way to go here.

My.Setting.Save() method works and saves what I need it to save. However, when I view the .config file the values in <usersettings>
<appname.my.mysettings> are not the same as those returned by the My.Settings.PropertyName

When you call the Save() method, does it not also save the changes to the config file?

There should be a folder within C:\Documents and Settings\user\Local Settings\Application Data or C:\Documents and Settings\user\Application Data folder i can't remember exactly where its at but if you browse those two locations, you should see a folder with your program name and in that should be your config file.

Hope that helps.

why EnableVisualStyles statement is not giving XP look to application?

JUNEYT26-Mar-09 6:31

Hi,

I tought that defining EnableVisualStyles would give a XP style look to application. However in design time when I define a backcolor for a button, The glossy look of button disappears. In the mean while, I set the one button's backcolor to system.window color, the glossy look of the button disappeard and now I can't give glossy look to button.

The question is how I can make a button look glossy with a defined backcolor.

Thank You.

What a curious mind needs to discover knowledge is noting else than a pin-hole.

In order to do this, you have to override the OnPaint event handler for the button, and do all the painting yourself.
VisualStyles for buttons is whatever the colour is set to in Windows itself.
There are loads of examples in CodeProject and on the Web. Search for something like 'Glass Button Visual Basic' for ideas on how to do it.

To enable Xp style look for the application go to project properties -> application tab. you will find "Enable XP visual Style" check box. recompile the application and it will work.

External Images

Hi all... I'm working on a report (Reporting Services) with an external image. The problem is it's not showing up. I'm passing the image through as a base64 string to the report and converting it back to bytes using the
Convert.FromBase64String function. The code is as follows

Dim location As String = Configuration.ConfigurationSettings.AppSettings("location")                
Dim reader1 As New System.IO.StreamReader(location)                
Dim base64 As String                
Dim BinRead As New BinaryReader(reader1.BaseStream)                
Dim file1 As New FileInfo(location)                
base64 = Convert.ToBase64String(BinRead.ReadBytes(CType(file1.Length, Integer)))                
Dim param As New Microsoft.Reporting.WinForms.ReportParameter("Image", base64, False)                
Dim al As New List(Of Microsoft.Reporting.WinForms.ReportParameter)                
al.Add(param)                ReportViewer1.LocalReport.EnableExternalImages = True                ReportViewer1.LocalReport.SetParameters(al)                ReportViewer1.RefreshReport()
.
.
.

Please ignore the BinReader / Reader bit. I havn't fixed that up yet. If someone can please tell me why this thing is not showing an image. I would be very greatful.

First you should convert your stream to Bitmap object then you can put it on Picture Image.

Bitmap bitmap = new Bitmap (stream);

Read your Text file to Line wise. You should need of Two string Arrays.
First one you put your File's Unique Data.
Second You use it for Counter.

Then check one by one your data to array.

how to change provider in crystal report runtime

JernejR26-Mar-09 0:02

JernejR

26-Mar-09 0:02

Hay developers

In Visual studio 2005 in Crystal Report Editor you can find "Set datasource location...". There you can change everything (mapping, datasource, even dataprovider). So far so good, but if you want to change DATAPROVIDER runtime (in code) you have big problem. You can change datasource to other database on the same platform, but you cannot change ORACLE to SQL database ??

It seems that changing DATABASENAME doesn't do anything. This is understandable because ORACLE (i design report originaly for ORACLE) does't have database name, you just specified SERVERNAME, USERID and PASSWORD.

So I think the problem lies in fact that you cannot change PROVIDER runtime??

So basicaly I'm able to change provider from ORACLE to SQL in IDE with no problem but not on runtime

I try allmost everything and nothing works form me (see example below).

BTW I'm IT pro and I know what I'm doing, so don't answer to my question like "do you have SQL started" or "is your password writen correct"
no ofense Roll eyes | :rolleyes:

If you have hundrets of report you cannot do this thru IDE.

Please help

It's been a LONG time since I've had to do this, but if I remember right there are two things you have to watch, the difference in table names between sql/oracle and I believe you have to refresh the object after you change the provider via .refresh .verifydatabase. That should force it to load the right dlls for the currently assigned provider rather than the one saved with the report.

The true man wants two things: danger and play. For that reason he wants woman, as the most dangerous plaything.

I didn't read the whole code but check the following

The cases that your code doesn't work are the names different in case (upper / lower case)
String comparison in .net is case sensitive so that might be the problem.
(use string.tolower or string.toupper on both strings that you are comparing to make it case insensitive)
