Detect An Image In An Email Message?
May 28, 2012I already have the setting in Outlook to prevent automatic downloading of images but I still receive e-mail junk mail containing stationary. There is even a setting that prevents all images but that is the problem: It does it to ALL images.I would like to trap and move all messages with any kind of image in it and send it to a junk-mail folder. Someone told me that I might do it with a plug-in or an add-on and that it might be able to do this in VB.

I cannot seem to make it appear.Even if I leave it VISIBLE at design time - the objects in it will not appear.Is there some kind of nesting problem that I'm not aware of!

Jumping Between Forms - Making A Form Visible And Not Visible
Jul 17, 2009I'm having an odd problem when making a form visible and not visible and it not continuing to function. Here is what I have happening. I have a main form (frmMain) that is an MDIParent. On this form I have a menu to open a second form (frmCalculate) and populate a listview from Items in the database.
As I click or select items in the listview on frmCalculate the tag is read and data is pulled based on the id stored in that tag and fills in various fields on the form. This works great. However, I also have a context menu attached to the listview that allows me to perform a "what if" scenerio on the items I am calculating. When I select this menu, I hide the frmCalculate and open the frmWhatIf form where I can mess around with values on the item I had hilighted in the listview on frmCalculate. Nothing is pulled from or written back to the database here, all the information is filled in from fields on frmCalculate. It just allows me to look at rising costs and how they will affect my margins.... anyway.
If I then close frmWhatIf, it brings my frmCalculate back by setting its visible propery to true (never closed frmCalculate, just hid it). At this point if I click an item in the listview I get an exception for a null reference. IF however I never hide frmCalculate, I can open and close frmWhatIF without ever having an issue. Why do I lose the functionality to select items just by hiding and unhiding the form? As a test I added two menus to the toolbar on frmMain one called hide and one called show. I then opened frmCalculate with original menu item to populate the listview and selected a few items to test that it was working and then using the hide menu I made the form invisible and the show button to bring it back. This yielded the same exception so without even opening frmWhatIf the problem still occurs.
Make Several PictureBox Images Randomly Visible = False And Then Back To Visible = True Giving The Appearance Of Flashing Or Blinking Images?
Jun 28, 2010I have placed several PictureBox Images of different colored dots(which represent lights) on an image of a Christmas Tree. I can make the lights randomly flash using a randomGenerator and a Select case statement. However, the code is very long. There are 67 lights on this tree and the code is 71 pages long. There has to be an easier way to do this. So far I have tried the following with two images of lights just to see if it would work and it does not work:

View 1 RepliesResults Should Be Displayed In A Message Box But Message Box Does Not
Nov 16, 2009I am using Visual Studio 2005 for coding. I am doing an exercise where I have to create a data lookup program. The program is to illustrate the concepts of using a database to look up information based on user input. The program allows a user to input two search criteria for a product search. The program then displays each individual search result, or record that meets the search criteria in a message box. I am not getting the message box and I don't know why. No errors are present during compiling so I have no indication as to where the problem is.

C# - Get ListView Visible Items?
Jun 25, 2012I have a ListView which might contains a lot of items, so it is virtualized and recycling items. It does not use sort. I need to refresh some value display, but when there are too many items, it is too slow to update everything, so I would like to refresh only the visible items.How could I get a list of all currently displayed items ? I tried to look into the ListView or in the ScrollViewer, but I still have no idea... the solution must NOT go throught all items to test if they can be seen, because this would be too slow.I'm not sure code or xaml would be usefull, it is just a Virtualized/Recycling ListView with its ItemSource bound to an Array.
View 2 RepliesCOM Visible DLLs: Are They Only Legends
Dec 5, 2005straightforward method of creating a DLL with properties and methods exposed to other programs? I followed the instructions that I found on the MSDN websites as well as suggestions from forum participants. The DLL should be available both for COM and .NET programs. So far, nothing has worked.There are numerous variations listed on the MSDN site. No doubt there are reasons for the differing instructions. However, I have not had sufficient success with any of them. Sometimes, just building the project makes the class visible to COM compatible programs. Other times, only after running regasm. Still other times, I have to run regasm, sn and gacutil before the DLLs class gets exposed. Then forums posters tell me: "you shouldn't have to do all that.

COM-Visible And Multiple Folders?
Jul 20, 2010I have built a com object in vb with the "Make Assembly COM Visible" that I use from the strange dialect, "Clarioneese." I maintain 2 versions of our main software, so I have 2 folders, one for each version.My COM object works from one of the folders, but not the other. I copied the exposed dll into both. I used regasm on the copy in the nonworking folder, but still, my Clarioneese programs can only work it if run from one folder, and not the other.Working Folder: C:cs46exe (I didn't name this, don't blame it on me)Non working folder: C:cssqlsdkv6 (I inherited this awful folder structure)If I move an exe built by Clarion into the cs46exe folder, the dll works, but not in the v6 folder.I thought I understood how this works, but I guess not. You can't be successful at this unless you're at least 1/2 a bubble off level.

View 9 RepliesGet The Values Of Combobox2 Always Visible?
Sep 4, 2009I am Working in vb.net .The only i found is C# .. "The fuction you want can be called "cascade comboboxes", i.e. there're two comboboxes and the items of the second combobox depends on the selected item of the first combobox. The basic way to implement cascade comboboxes in a DataGridView is to handle the EditingControlShowing and CellValueChanged event of the DataGridView. in the EditingControlShowing event handler, if the column in question is the second DataGridView combobox column, change the data source of the editing control (DataGridViewComboBoxEditingControl) to another data source and filter the new data source.... In the CellValueChanged event handler, if the cell value under the first DataGridView combobox column is changed, clear the cell value under the second DataGridView combobox column in the same row.."
The Problem is this: 2 ComboBoxColumn already with their dataset (via propretries of datagridview design) and the DGV2 is a detailed datagidView Reffered to a Master which is another DGV on the top of my Form. So in DGV2 the first ComboBox 1(column 2) displays data .According to this Data the other ComboBox2 (column 3 ) filtered. The problem is that when you select more than one time the same value of the Combobox1 and then you try to select another value the displaying data of the ComboBox2 dissapears.
keep the values of combobox2 always visible..
