Re: Multiple Bitmaps - Visual Basic Discussion Boards

Is there a property that can be set for a ListView that will allow it to show (or block) certain file types?

I have directories that contain several image file and a few text files. In my list view, I want to display only the TEXT files.

I can cycle through the files and display only the *.txt files but this is time consuming since most of the files are not text files so I’m just trying to find a more efficient way.

Thanks.
Brad

No, you have to filter the list yourself, just as your doing. The ListView doesn't offer any kind of built-in filtering.

If your binding the ListView to a datasource, you can apply filtering to the dataview that your binding to, but that's about it.

Thanks Dave.

After playing around with my code I found that I was looping some things that I didn’t need to. It still hesitates but it’s acceptable.

There is a object defined as:

CREATE TYPE Book_t AS OBJECT(
name varchar(10),
author varchar(10));

CREATE TYPE BookSet AS TABLE OF Book_t

and a function defined as:

CREATE FUNCTION GetBooks() RETURN BookSet

How do I call this from a VB.NET application?

MS says "Snaps-Ins can be designed to function in Web browsers as well as the MMC." I've written an MMC snap-in with VB6, but how can I put the snap-in in a Web browser?

I've developed a program that reads animations (in GIF format) it reads each frame and I can display each frame on a Form in seperate PictureBoxes, what I would like to do is save the entire picture as a bitmap or a jpeg, which I can't do is there anyway to do this can someone help me.

What do you mean by "entire picture"? Are you trying to save the full animation of the .GIF as a .BMP or .JPG? You can't because neither format supports frames. They don't support animation...

"...a pungent, ghastly, stinky piece of cheese!" -- The Roaming Gnome

what i mean is that when I click on a button called Add Frames, it adds each animation frame onto seperate picture boxes, which displays each animation frame as a bitmap on seperate picture box. This is what I want to save. I will list my code here. If you go through my code you will see that each each animation frame of a gif is separteley displayed on seprate picture boxes this is what i want to save, all individual bitmaps which are on their own picture boxes as a complete bitmap or jpeg. here is my code:

This is my animation class that grabs each frame of the animation:

So you want to save each idividual frame as it's own .BMP or .JPG file?

Then just iterate through the PictureBox's, just like you added to the Form (or parent PictureBox in your case), cast a Bitmap object to the Image property of the PictureBox, then supply the filename to save it. You already have most of the code written, the rest is easy.

For x = 0 to UBound(PictureBox(), 0)
    Dim imgBitmap As Bitmap = PictureBox(x).Image
    imgBitmap.Save(strFilename, ImageFormat.Bmp)
    'increment your filename somehow, somthing like
    'MyAnimation0001.bmp, MyAnimation0002.bmp, ...
    imgBitmap.Dispose()
Next

I can already save each individual frame as a seperate bitmap.What I want to do is save all the animation frames as a single bitmap file.So when I open up that single bitmap file in Microsoft Paint or Paintshop Pro it displays all the frames of the animation in a single bitmap file.

For that, you would have to make a bitmap and loop through the frames. Then, draw the current frame on to your bitmap at the ending position of the previous frame.

Yes thats what i want to do, but i don't know how to do it. Can someone help me with that please.

1st question
how could i move the form by the mouse ofcourse not from the title bar
or how could i make a label and by mouse down i can move the form and when up the mouse it leave the form at the new place

2nd
now i make a game and i want to make to things
first a shortcut key when i press it start a new game
like if press f2 start a new game how?
second in new game have i to clear changes i made one bye one or there is a code to load the form as it loaded in the first time

3rd
i knew how to make a control array of a control like a control array of commands when u clicked one the tabindex is ur guide and i make a notehr one how can i bound the two control arrays

You would have to experiment with overriding the MouseDown and MouseUp events of the Form. During MouseDown, you would probably have to use the PointToScreen function to calculate the coordinates to use and change the Top and Left parameters of the Form to those coordinates. No, I don't have any sample code.

This depends entirely on your game's engine design and can only be answered by you, the person who designed it. The key would be handled just like any other keydown/keyup event in your game. How you reset your game engine depends HEAVILY on the design of the engine.

"...a pungent, ghastly, stinky piece of cheese!" -- The Roaming Gnome

I have a custom collection set that contain specific items and/or a set of items of that same class. (Much like a Windows folder, any collection can contain one or more "shortcut" items, as well as other "folder" items - which in turn can contain the same kind of items).

I have the class collections and representations mapped out, but I am having a heck of a time implementing XML Serialization/Deserialization around the set.

There is a very helpful article on XML ser/deser of a custom collection class, but it is not recursive.

Can someone point me to an appropriate document?

Thanks;

I created a Class library in a multi-project solution. This library is being referenced by many other libraries in different projects in the same solution. When I compile this library I would manually remove references to this library and then reference it again. Is there another way to do this?

Hi,

Another way of doing this is use the Reflection Class,which dynamically
Loads the Assembly at run time. and also Unloads the Assembly.

So, you use the Assembly when ever you want at Runtime.

Regards,
Sukesh.

Sukesh.g

The problem is probably because you are using automatic versioning in your Class library project. Open the Assembly.vb file and change the Assembly Version attribute from "1.*.*" (auto-increment versioning) to "1.0.0.0" or whatever you want for a version number. Then, all your other projects that reference this assembly will reference the same version of the assembly.

In other words, your projects are referencing your Class assembly. When that reference is created, is it created with the version number of the last time you compiled the Class into an assembly. The '*'s in the Assembly version attribute of your Class project denote numbers where the compiler will automatically increment the version number. When your other projects that reference this assembly are run, they load the Class assembly with the same version that was used when the reference was created. If your app references your Class with the Class's version at 1.0.2039, then the app will always expect version 1.0.2039 to be there.

Now, if you set a reference to the Class assembly, you'll run into the problem that your having now. If you create the reference to the Class project, the versioning problem will go away, but you'll still have to change the Assembly version of your Class project to a static number. Otherwise, when you compile your Class assembly, you'll have to recompile all the projects that reference it to.

Thanks. I finally got it.

Hello,

I'm very new to VB so maybe the solution I'm looking for is easy to find but I just can't find it... Confused | :confused:

I have an access database with companies datas; this database is read by a VB application ( prev, next, search...usual stuff ).
The fields are:
Company
Address
City
Phone
Fax
Email
Comments

What I would like to add is:

a combo box which will autoupdate itself based on the database records, so when a user is selecting an item from the combo, the corresponding record become visible on the interface fields.

It is possible to have something like this? I did the thing in Access but it looks like there are many differences between VB code and Access code...

Thanks in advance.

Axel

Access code is VB code, just more limited. Visual Basic for Applications (VBA) is a subset of the full language. When coding Access apps quite a lot goes on 'behind the scenes' that you can't easily see. When manipulating a db with VB directly, you have to provide that functionality yourself. If I understand your question correctly, you are trying to populate a form with data that depends on a user selection from a combo box. You need to provide a function that intercepts the user selection event and executes a SELECT query on the database, then update the form controls with the resulting recordset.

Thanks a lot, Roger. Smile | :)

I got the idea.

Can anyone point me to a class for creating an Application Task Bar in vb.net? I have a CS class, but it is incomplete and I am not having much luck repurposing it.

Either source code, or even a control that I can purchase that would allow me to dock a bar to the screen, hide it, etc.

Thanks;
M. Rich

Have a look at this:

John O'Byrne's
taskbarnotifier, a skinnable MSN Messenger-like popup in C# and now in VB.NET too
http://www.codeproject.com/cs/miscctrl/taskbarnotifier.asp

Not exactly what I am looking for, but a cool control.

I'm looking for a class that implements the Application Task Bar functionality of Docking and Hiding, etc that you get with typical XP-style toolbars on the Windows XP desktop.
