Visual Basic 6.0 Image Handling


Hello friends,
I want to ask you a question about handling
the images with Visual Basic 6.0:
- There are functions in VB - Getchunk and AppendChunk
with which you can read and write binary image data to
records in a database (BLOB field) - this works fine.
- I have a form on which the user can choose a picture
with a dialog box. After the selection I need to store
the image in the BLOB field in the database, so I have
to convert the image data into binary variant which
could be written using the AppendChunk method. I don't
know how to do this!?
- The image has to be stored in a BLOB field, because
I use Crystal Report to show this picture, and, as far
as I know, there is no other way to show a picture that
changes in a CR.
Could you please help me... I lost too much time reading
forums on Internet and didn't find a solution for VB6,
only for VB.net.
THX in advance,
Best regards,
Zoki

Visual Basic 6 Error Handling
Hi Expert,

I have a quick question regarding catching an error. Particularly PRINTER error. What I am trying to do is, to print out the Visual Basic Form. I do have an error handler. If the computer hooked up to a totally different printer, then error will get caught. HOWEVER, if I am hookep up to the correct printer, and for some reason the printer accidently disconnected, the error can not be caught. Please give me some suggestion. Here is the code:

Thanks.


Code:
Private sub print_form()
On Error GoTo err
Screen.MousePointer = vbHourglass
Frame1.Visible = False
frmNewBiz.PrintForm
Frame1.Visible = True
cmdPrint.Visible = False
cmdReprint.Visible = True

Exit Sub

err:
MsgBox "Please try again! " & vbCrLf & "Error #:" & err.Number & vbCrLf &
err.Description, vbCritical, "WARNING!"
txtPolicy.SetFocus

End Sub

EMbedded Visual Basic - Comm Handling
Hi friends,
I have an HP ipaq Pocket PC with windows mobile as operating system.
What I am trying to do is to make it communicate with an RS232 serial device(card reader) without the involvement of the host pc.
i.e, direct PDA to Device.
I have installed and configured all the eMbedded VB resources in my system and i am able to create and run normal applications from the PDA.
But I have only a cable which can be connected from the PDA to PC (this end is USB).
How can I proceed from this point? Is there any hardware connector is required?
Please help.

thanks in advance.

Handling Power Point Through A Visual Basic Application
Hai Everyone,
   I have a query and please hel me with this.I have to launch a vb application which can control the following conditions:
1. The application should have a button - "Launch PowerPoint" - clicking it
launches PP.
2. The application has a browse button to select only PP files. On clicking
it, it brings up a file selection dialog in which only the PP files are
enabled for selection. On selecting a file, it opens into PP.
3. The application has a "Play" button. On clicking this, the PP brings up
the slide show.
4. The application has a "Next" button. On clicking this, the PP proceeds to
the next slide in the presentation.
5. The application has a "Back" button. On clicking it, the PP goes back to
the previous slide.
6. The application has a edit field which takes only numbers. A check box
labeled "Custom Timing" enables or disables it. When enabled, the contents
of the check box is taken as the time separation between the slide changes -
if "Next" is not clicked by then. For e.g. if we enter 10 into the edit box
while the PP is playing the slide show, then if we do not press "Next" for
10 seconds, PP displays the next slide automatically. This you do by
changing the slide flow information of the presentation slides.

I badly need help in this regard please help me out.

Thanks and Regards

I have developed a GUI with corel drawn and now I want to bring it to Visual Basic to give the code behind the graphics, I have already export this image to visual basic and used the Image tool to do it, also I have tried with the Picture box, but now since they look like buttons that you can make click I want to map the image in a way that when you make click inside the border you can open other screen, this is a special image that has different shape from a comand button. I know it is related to image mapping but so far could not find so much about it and specially simple examples. It will be really helpfull to me if you can give me some hints or information related to it, thanks.

TIFF Image And Visual Basic
Hi,
I'm trying to save a TIFF image in a Database SQL Server with a Visual Basic aplication , but I have many problems.
The first is that I don't know the equivalence between an Image field in SQL Server with the Visual Basic datatype. I think that I must do a convertion type when I open the TIFF file .... perhaps binary convertion ?
And the second is that I must send this TIFF Image to an ASP page but I have to convert this Image to JPG or GIFF format, and I don't know how can I do it.
Thank You.

Visual Basic With MS Access Image
Hi,

what is the best component to use when you want to display an image in Visual basic if made used of an MS Access database to store the image? I have made use of the OLE component with the following code in order to upload the picture to the OLE component - but it does not want to show the image:

ON Error GoTo ET

strfilepath <> GetFile(Me)
If strfilepath <> "" Then
OLE1.SourceItem = LoadPicture(strfilepath)
End if
Exit Sub
ET:
Exit sub
End Sub

The idea is that when the user click on a button to add new record, he must complete all the fields - then when he get to final field where he must upload his picture, he must click on a button, search for his picture, upload and then click on update in order to write everything to a MS Access database.

Visual Basic Items Removed From Visual Basic.NET
A while ago (maybe up to a year) I had found a web page (probably a Microsoft MVP's home age) that had a list of about 100 things that were removed from Visual Basic in the transition to Visual Basic.NET. As it is, I would like to look at that again, but I can't seem to find it on my computer. Does anyone remember this page and/or have a copy of the link or the file that was on it. It has particular things like Debug.Print is no longer valid and MsgBox function is not supported. I've look on Microsoft's website and found a great deal of information about implementation difference, but I can't seem to locate this particular piece. If anyone could help I would appreciate it very much.

Thanks in Advnance

Image Handling While Minimized?
hi guys,
i have written a VB app that loads an image and reads it to recognize some easy mono colored characters but VB cannot read it when minimized or there are some other programs over it. I see the reading function GetPixel or some similar one needs DC for the image box and x,y for the point, then why it needs to see it directly from outside-like style. if it sees like that then why should i send the DC? i should sendt the x,y and that function should read the x,y of the current 'screen' and return its color value. It does it that way because it cannot read when there is other fomrs over it but it also needs DC. isnt that strange? i need to make that read while minimized also. does anyone has any idea to do it and please tell me why it needs DC while it directly reads from screen x,y? (i mean it can use the screen dc if there is one, there should be i believe).

Image Exporting And Handling
While working with MSChart I've seen it has a method called "EditCopy" and then you can save it with SavePicture as a BMP. Is there some class module or plain module out there that would let me save the graph in other formats like JPEG, GIF, and/or PNG?

Also, is there any way of loading PNG files in a picturebox? without using some other non-standard OCX.

Image Handling ActiveX Controls
Hi

I have used an image handling control from Olympus S/w, called ImageKnife.
The functions provided by this one are good. But some do not work for Colored images.
So we have made the utility only for color depth. ie. Black and white.

I just want to know what other Image handling controls are in market and which can handle functions like
Overlapping one image on other, either complete overlap or transparent
or
selecting area on pict. or blacking out selection

Almost like Windows PaintBrush/PhotoShop. (The only purpose of making similar utility was that we provided symbols related to Telecom Network which can be inserted. )


etc etc

Please inform me if you have used any such control.

Thanks

Rich Text Box Image Handling
Hi everyone,

The program I am writing has a rich text window showing particular types of
data message, and my plan is to insert a small BMP image before each message
depending on its type.

So far the images are showing up fine, but when you click the image it
allows you to resize the BMP to arbitrary dimensions.

Is there a way to gain access to the properties of these images at run time
to disable this behaviour? Or is there any way to redirect/ignore the click
event on these images?

I've successfully tried both the 'clipboard - paste' and 'OLEObjects.Add'
method to print on the RT Box but both behave the same way when you click an
image. Locking the text box has no effect either.

Any clues would be greatly appreciated.
