i made a class library with by adding two .jpeg images and changing build action property to embeded resources and i saved i want to use this two images from this .dll into my application .
View 9 Repliesrecently i have been working on a desktop project, and i made couple of changes to the project, one of them was changing the build action for the App.config to "Embedded Resource" by mistake! after that i built the application and no compile errors were shown, so i tried to run it but the following run time error showed up:
{"An error occurred creating the form. See Exception.InnerException for details. The error is: The URL cannot be empty. Parameter name: url"}
but it did not specify more information about the exact cause or the exact error place. so it will leave you in a miss!
for awhile, i did not know what was the cause of this due to the numerous changes i did, so i started to review my latest changes one by one till i discovered that changing the build action for the App.config file was the reason for this error.
When having hundreds of .rtf files in an app, is it best (and Quickest) to set the "Build Action" as "Content", "Resources" or another property setting?

View 10 RepliesI'm having a problem with displaying JPEG images in a RichTextBox. When I insert a JPEG image into a RTB it automatically gets converted to a wmetafile8 and displays correctly - however, if i insert a JPEG image into file via another method (currently using the web) it get saved as a jpegblip (as you would expect) but the RTB will not display it. Opening the rtf document in Word displays the image correctly.I have tried this with png and gif files also but none of the images will display unless they are wmetafiles. Is this a limitation with the RichTextBox or is there another reason?

Now this works fine in C# , however in vb,net the line where I add the event handler generates the following error on the message.callback property : Property access must assign to the property or use its value I am tearing out my hair on this I have never used the Action of T delegate before so could i be missing something simeple ? I can provide the c# code as well.

View 1 RepliesAlright, say I've made an animation in photoshop and exported it as a JPEG. I want to know if it's possible to change which frame of the animation the image will show. An example is if I made an image with 10 layers, and I want the 5th layer to show in a picturebox, how can I achieve this?

I've copied the files albanyc.ttf and MTCORSVA.TTF into 'Resources' and set the 'Build Action' for both to 'Resource'. A label is set to one or other of these fonts dependent upon what is being displayed. This works fine on this PC but when I copy the program to my laptop it seems to me that neither font is used and the same 'other font' is used in stead of either of the ones I want to use. I tried setting the build action to 'Embedded Resource' but that made no difference and I got an error message when I tried 'Compile' (I kinda expected that, but thought it worth a try). Both CP and laptop have the same OS, Win.7 64bit, the only difference is that the PC has Pro. and the laptop Home P.

I simply want to have a list of all graphics saved in specified folder displayed as miniatures - this suppose to be a sort of an image browser - it does not have to be done using ListView, so I'm open to any suggestions.
I need to loop through a very large collection of images and resize them all to 400x600 pixels. Is this possible?
View 5 RepliesI have a ListView that I am using to display specific data. In most of the columns, I have images that represent supported types. When I add these images and build the project, they go away.It worked for a few weeks until they suddenly disappeared.

From my DLL project I have succeded in making AutoCAD launch by pressing F5 from VB.net IDE (Visual Studio 2008) en route to try to make debugging of the DLL easier ...
... however one last obstacle is currently in the way and the obstacle is that for some reason when I hit F5 and AutoCAD is launched my breakpoints are not recognized at all... and program runs from start to finish instead of allowing me to debug ...
It issues a strange message which says "The following module was built either with optimizations enabled or without debug information... to debug this module, change its project build configuration to Debug mode..." and it is all weird because as far as I know I am not in release mode .. but in debug mode (anyhow I am relatively new to Visual Studio .NET so I am thinking that my impression could be that I am in debug mode when in actuality I maybe in release mode)...
Here is why I think I am debug mode ...
1. From Solution explorer ... when I click on the Solution Name and view its properties ... the Active config property says Debug|Any CPU
2. When I look at the properties of the project and look at the compile tab it says that the Configuration is Active (Debug) and under Platform it says Active (Any CPU).
3. Under the Advanced Compile Options of Compile Tab from project properties ... Enable optimizations is UNchecked ...
Anyhow with all the settings mentioned above it seems that I have everything okay but then the message above proves otherwise ... and so at this point I know that I am still missing something ... like a setting somewhere... wondering what else do you think am I still missing?
As additional info...there are seven projects in the solution and it is the main one (the one that I set as startup project) whose properties I refer to in all the paragraphs above.
I'm programming in VB using Visual Studio 2005 Professional. I have a code munger perl script that generates some of the *.vb files that I want to compile. The script and the associated files are in my project directory, and when I run the script from the OS command prompt, it writes the files in the same directory, which is what I want. Rather than do this, I want to invoke the perl script as a pre-build event. I've gotten it to work ... almost. The only issue now is that the files are now deposited in TargetDir (/bin/Release e.g.) instead of ProjectDir. I could just change TargetDir to be ProjectDir, but that seems like I'm asking for trouble. Is there a way to separately specify the target directory for pre-build commands? Or change it to ProjectDir, then change it back after I'm done with the pre-build?

View 3 RepliesI have an Inherited Control with a Property that can be set in the designer. There's some code in the Set procedure to make sure it's set appropriately. However when I build or run the project that property is changed, I am assuming it's the sanity check code in the Set procedure that's causing it to be changed along with some VS beahviour.

I'm working on my second project; a layered image displayer.
It works like this:
- The user adds a new "image layer"
- The user can set the texture, image, size, rotation and color
- This all can be done using a selection square and some dialogs
It all works fine, but I found that there is one thing still unclear to me:
- Can you render layers without totally starting over (refresh) on every change?
As example, I have 200 image layers. I change one image layer somewhere in between them, and the program has to refresh all those images. (1 - 200)
This takes awfully long.
Now I found a small solution; I gave all layers a "finalimage" so it can render a single layer. Next I used, in the program, a back, active and fore layer. This way the program only has to render 3 images when changing the "active" layer. When you select another layer, all 3 layers will refresh. (with all those 200 layers).
Here is the code to get an idea:
Dim OLDINDEX As Integer = -1
Dim BackLayer As New Bitmap(800, 600)
Dim ActiveLayer As New Bitmap(800, 600)
Dim FrontLayer As New Bitmap(800, 600)
Public CurrentIndex As Integer = -1
Public PerformGlobalUpdate As Boolean = False
[Code] .....
It all works fine, but the only problem now is that it takes ages to select a different layer.
a datacontext defined in a module(domain services ado.net ria)a page having add/delete methods whenever any method is executed, it is found that all the previous actions (NEW RECORD ADDITION and DELETION OF RECORDS) are carried out before the new action is carried out normally
this behaviour is not prominent but "when using break points and inspecting the values of the variables and table object to be added to context, it is clear that all the previous actions take place again. even when the datacotext. savechanges is called, even after that still all actions carried out on the datacontext repeat themseleves, when any new action is to be carried out
I am using a custom built driver to communicate via Modbus TCP with a Windows CE Controller.
There is a property declared in the driver as a SHORT. I need this property declared as a LONG. I have tried everything I know of to change this programmatically but I am having no luck.
' Declared in the class
Dim dev As vHMIModbusMaster.CDevice 'this is the Modbus Comm Library
Dim WithEvents MBSerial As vHMIModbusMaster.CModbusSerial
Dim WithEvents MBEthernet As vHMIModbusMaster.CModbusEthernet
[Code]....
Address is sent to the event from a timer event. It is the .Memory_StartAddress that I need to be a long.
I come from a VB6 background and have only recently started using .net. The developer of the driver has been very slow to respond and I am having a hard time convincing him that the problem is with his code. The thing is that it works fine as long as I send an address less than 32767.
I have a form which has ONLY three buttons. Somehow they got named Button5, Button6, and Button7.

Is there something I can do to enable the renaming?

I have a form with a dropdownbox two listboxes and two buttons on it. I removed a "select" button as I just used the DropDownList1_SelectedIndexChanged, but the event would not fire until I used the suggestion from:Why DropDownList.SelectedIndexChanged event does not fire?
It involved changing the AutoPostBack='true' and EnableViewState="true" properties
So now the DropDownList works but with the two listboxes, the SelectedIndex stays as -1 and does not change even when selected.
[Code]...
I think it has something to do with post backs, page_load or the selectedindex changed event of the listbox, it worked perfectly before I made the modifications.
Let's say I've got a TableLayoutPanel with 50 cells in it. Inside each cell is a separate text label. If I want to change the color of each of those 50 labels at run-time to the same color, is there an efficient way to do it? (so that I don't have to write 50 lines of LabelX.ForeColor = X, etc).
Not that I would mind writing 50 lines of code for this, but I would like to figure out the most efficient way to do this sort of thing, for future reference.
