I am writing an app that includes the use of a NumberUpDaown control. I just stumbled onto what seems to be a 12 bit maximum limitation (FFF,4095). I've set the Maximum properties for 16 bits, 65535, but still see a 12 bit limitation. I suspect this is a MS limitation but I've found a description of this control which states it should be good for 16 bits.

View 4 RepliesI have both Visual Studio 2008 Express Edition and full blown Visual Stuido 2005. I create a simple Windows form that connects to an Access Database on both IDE's. I use the built in controls that are automatically added to the form to SAVE, UPDATE, and DELETE, and TRAVERSE records when you drag and drop a column from the dataset to the form. HOWEVER, I find that on the express edition when I click "Save" the changes are not applied back to the database!?! When I do the project in full blown VS2005, the changes are applied.
View 5 RepliesI'm working with a form that doesn't want to let me go above 884 for height when I'm working in the editor. I thought I figured this one out before but my memory could definitely be better. I've played around with a bunch of properties without success.opping controls on the form and locating them below the bottom limit doesn't do it. The form will go down as far as necessary to show the new control when you run the application but not when I'm in the editor. I want to be able to work in the editor on a form greater than 884 height

View 4 Repliesis there any way to get a numberupdown text to show the value "+" so if the value is a positive number then it adds the plus sign in front of the digits.
example:
2.00 would become +2.00
3.25 would be +3.25
as when its negative its
-2.00
-3.25
It already adds the negative value when its negative of course.

I'm using Visual Basic 2008 Express and am having problems making an install.It has been suggested that the Express (free edition) only allows you to install only on computers that also have Visual Studio.Do I need the Full version to be able to distribute my application to a variety of computers?
View 2 RepliesI have a slightly unusual application that is optimally designed by doing the following. We have an application that references a number of graphic sets for unique artwork utilization. The application is in HD and the graphic sets are a bit large about 20 megs per set. We have found that the optimal design for this particular application is to create a unique .Resources file per set, compile this .Resources file into a .Dll file using Assembly Linker (AL.exe) and reference the .Dll via the application and load the graphics upon demand or selection actually of this unique set within the application.
Question is this as I have been unable to find any data on this aspect.
Is there a limitation on the number and size of .Dlls that a VB .Net application can reference?
Specifically, we will likely have 20-25 unique graphic sets reesulting in 20-25 unique .Dll files of about 20 megs per .Dll. On our deployment boxes for the applications, we have 2 GIGs of RAM so no issue there.

View 17 RepliesWe are using VB.NET 2008. This program must run on a 32 bit operating system.
The machine where the program is running at is a 24 core machine which has 16 Gig of RAM.
It has a Win Server 2003, Enterprise Edition SP2, x86 based PC.
When the VB.NET program VM Size reaches about 1.3 Gig, it says "Exception of type 'System.OutOfMemoryException' was thrown."
When I go to Task Manager and check the Processes, "Mem Usage" for this program is about 300 Meg and "VM Size" is 1,341,300.
These are the information from Accessories - System Tools - System
Information:
Total Physical Memory is 16.37 Gb.
Available physical memory is 14.46 Gb.
Total virtual memory is 17.74 Gb.
Available virtual memory is 15.73 Gb.
Can my VB.NET 32 bit program access more than 1.3 Gig of VM in Win 2003 SP2 Enterprise edition ? How can it do that ?
According to [URL] the memory limit on this kind of machine with x86 is 64 Gig.

View 3 RepliesThe following code works perfectly to allow moving a control on a form at run-time. However, when AutoScroll is set to True on Form1, and you drag Button1 past the right and/or bottom bounds of the form, it goes haywire. I really need someway to smoothing control the autoscroll so that as you scroll the control off the form, the scrollbars smoothly appear.

I'm writing some VB2008 code to control four 7-seg LEDs I bought from Velleman. They came with some example code in VB 5.0, and with instructions telling me to input 5 bytes at a time in the format Chr$() & Chr$() & etc. for the rest of the 5 bytes. When I try to do this using VB2008, it rejects the $ sign, so I've tried it using the Chr() format, which VB2008 allows. However, it doesn't work. Is Chr() the new version of Chr$() or are they different entities? In sending data to the LEDs, I'm using LiveComPort.WriteLine() as my command. (My serial port is called LiveComPort) I also tried it with LiveComPort.Write() asthe command. I know that my serial port and the LEDs are working, because they respond to the demo program provided by Velleman.
View 7 Replies1) How can I make the text in RTB control to change without clicking on it (RTB control) again? I notice that the event handler is mousedown so its only occurs whenever the users clicks on the controls. But I really have no idea how to do that. Anyone can guide me how to do that???
2) How to make the RTB's Back Color to transparent??? Cause it is not supported. Or is it I use the wrong control???

View 3 RepliesI am programmatically creating a Tabcontrol and adding Tabpages to it. To each Tabpage, I am adding 2 Pictureboxes (Testpicture1 and Testpicture2). The amount of Tabpages depend on the amount of frames in my .tif file. So, each picturebox holds an image (frame) from my .tif file sequentially from˜0 to totalpages. All good so far. I can click each tab and correct images are displayed in correct order. The problem is that when I drag a control (picturebox) and try to add it to Testpictue1 or Testpicture2 it does not work correctly. At first I thought the it didn't work at all, but when I checked each Tabpage I have found that all pictureboxes got added (draped) to my last Tabpage, in this case Tabpage4. So this is puzzling. Even though each Tabpage holds 2 Pictureboxes and they display the correct images yet the picturebox is added to the Testpictue1 or Testpicture2 of the last created Tabpage? [code]

i wanna ask if its possible to add another control to a control... let say that i have a toolstrip and every time i will click an item it will add a picturebox in a workspace as a control, and after clicking and adding one control it will add another control as a layer of the first control??
View 4 RepliesHere's my situation: I have a control with motion graphics (for the sake of simplicity, a 'video player' control) in my project. Think of a PictureBox with constantly-changing images. In front of this will sit a second control (such as a second PictureBox of the same dimensions). The topmost PictureBox will be drawn to in its Paint event.
I need to draw very few elements, and the bottom control is updated much more frequently than I need for this drawing. So these elements are drawn to the topmost control. Think of a news broadcast, where they have live video in the background, with a news channel logo, news ticker, and sometimes gradient visible in front.
I'm trying to create that 'foreground' control, and the closest I believe I have gotten so far is the following:
Imports System.Drawing
Imports System.Drawing.Imaging
Imports System.Drawing.Drawing2D
[CODE]...
The 'Opacity' property in the code above is a sort of "scaling factor." The image drawn to the top control may, in different parts of the image, have any alpha value from full transparent to a full 255. This 'Opacity' property is applied to the entire image being drawn, scaling the alpha values of each pixel.

when I add a Control to the List(Of Control) what gets added to the List? Is it the Control or reference to the Control.I have a collection of controls (picture boxes representing notes,comments, icons, etc.), which can be drag and drop into other picture boxes holding read only images. Those controls are never permamently added to those images, they can be move or dispose as needed. I need to save those controls to a file and retrieve it later, however when retrieved, they must be place onto the same location in the image. Saving just the image is not the option, I also need to save all the control attributes.
