One of my programs uses transparency so that the form is the shape of the background image (.png). My problem is that everything works and looks fine on the computer I'm developing on (Win7) but when I run the program on my other computer (XP), instead of the transparency I get the background color (which is the same as the transparency color). Does anyone have any experience this problem?

I've making a program that must crop 20 squares out of a larger image that is in a picturebox. Now I've created a Draggable rectangle control and set it's Background to transparent. This is working (kindof).
Now I have set my control to doublebuffered = true and it Removes tha annoying flicker.My problem is that doublebuffering creates a new problem. My control's parent is a picturebox with a large picture inside.When I move my control over the picture to select the area to be cropped it updates slowly I.E The control Is in a new area but it still displays the old area and then updates which is annoying.If you want to see for yourself create a new project with a picturebox with a Image inside with my Control as a child of the picturebox.

I have thought of possible solutions but they might well be much slower.#1 Copy the part of the picturebox that is under the control and paste it on my control.#2 Somehow eliminate the backcolor property thus eliminating the need to paint something over the control and only paint needed parts .
I have a form, which has the background color set to the transparency key color. On the form there is a picturebox with transparent backcolor and a picture that is semi transparent.Unfortunately the transparency doesn�t work. The form shows with a background, but not the background color I chose, but the gray control color. Nothing is transparent.The EXACT same thing works with another form.
View 4 RepliesI decided to have a play around with the Windows API Code Pack and so far it has had some very interesting things. Something which I like in particular is AeroGlass. I have created a project to mess around with it to see how it works etc. and I am having some difficulties with the tranparency. If I put a textbox on the form for example, it displays fine. The text however is barely readable unless the form is over a dark background. The solution seemed obvious. Change the transparency key. However, there wasn't one set. Adding one stops the glass effect from working.

I need to build a program that combines many different .doc files based on which check boxes the user selects. At first I was going to use the word.document.open(file) way, but I would rather not have to open 40 different files every time the program runs. I then turned to streamreader, which works great for basic text (after I convert the file to .txt) but I can't figure out a way to maintain hyperlinks. I am now thinking that after the streamreader reads all of the data and combines it into one string, it will paste it into a word doc and somehow search for hyperlinks and make them active.
View 1 RepliesMy program references a specific object that is contained in a list. The references point directly to the object itself, instead of its position (index) in the list, since that might change over time as other objects are added/removed. However, occasionally this object is edited, and (behind the scenes) this sometimes involves replacing it with a newly-created object (so the code looks like ListA.item(i)=new testobject...). In which case, if my understanding is correct, all the program references to this object are no longer correct, since they point to the replaced object instead of the new one. So I'm wondering how to maintain the integrity of the references, since the list index is not permanent, nor is the object reference technically permanent. Should I create some ID number for the object, and maintain and use it for references (so the new object would get the old one's ID)?
View 8 RepliesI am working on a new domain model for an application that will have order processing for items built in (well, too keep it simple for this question anyway). I have a class "VendorItem" that represents items that can be ordered. Originally the "Order" class was going to have a list of VendorItems associated with it, but I have come across problems with it so far.
Let's say that the system has been creating orders for some time just fine. One day a user comes along and decides that a vendoritem has changed price or some other detail like packaging size. I wouldn't want the previous orders to be affected by such change. At first wash I was going to make a "OrderLine" class that is basically a copy of the "VendorItem" class, but that just feels (smells?) wrong in the OO sense. Is there a better way to refactor this so I don't have copies of classes and information in the domain model?
I have three radio buttons defined within a frame (optRptType_0, optRptType_1 and optRptType_2). I set the checked value to true on optRptType_2 to use as my default. I have the following checkchanged event defined for these radio buttons

When the form opens the optRptType_0 is checked. I am trying to determine why the optRptType_2 is not checked as that is the default I set up. I tried adding the line "Me.optRptType_2.Checked = True" to the Form Load event but it had no affect and the optRptType_0 is still the entity checked when the form opens.

I have the [B] [I] [U] buttons and they work to a point but here is the problem I'm having.In MS Word,I can Hilight text and select Bold and it bolds the text, I can then select Italic and while leaving it bold, it Italicizes it.I can then click the bold button again and it will remove the bold but leave the selected text Italicized.

View 14 RepliesI have an issue with maintaining scroll position.I am almost positive that I have everything set correctly. I have updated my web config...
<pages maintainScrollPositionOnPostBack="true"
and everything seems to work fine UNTIL....When ever my Gridview returns a lot of pages, like more than 50, sometimes upwards of 100 or more, I show 50 records per page. The farther into the Gridview, the more the scroll position is off.So what I am saying is that for the first 20 plus pages or so, if I scroll down the page to the point where the top rows have moved off the screen and I enter Edit Mode, the correct record remains in view on Postback.But if I am over say around 30 pages into the Gridview, the further in the worse it gets, when i enter Edit Mode I have to scroll back down to the location of the record that I selected to edit.
I have made an employee list and linked it to an Access database. The initial problem I was having is that in my program I had to link their ID's and names so if you click on an employee in the listbox, his or her's ID would automatically display in the textbox below. Since I did not know how to do so, I decided to make an array and store the ID and names separately while the listbox is being compiled. And so, the form became linked and adding became easy to code.But my problem came in deleting an employee. When deleting the name should be removed from the list, but this is where the order of the arrays messed me up. How do you maintain the order of the array? Here is the code I used. I dimmed 'count' as an integer and it is responsible for keeping that order.[code]You will see Staff_CodeTextBoxes etc. and info_Staff_CodeTextBoxes. etc.These text boxes (not visible to the user) are responsible for holding the data while the array takes the data from it, or adds it's own data to it.

Launch a dialogue window from the main form, and then another dialogue window from that dialogue window. If you close the second dialogue window and call dispose the main form vanishes under any other open windows. This doesn't happen by closing a dialogue window normally, but I am attempting (rightly or wrongly) to stop memory useage creeping up by disposing of it.
So, the question is - what method can be employed to maintain the position of the windows?
I have a picturebox on a form. The image in the picturebox is actually a report. I want it so if the user clicks on it it will zoom larger --- while the picturebox remains the same size. Of course, the entire image will no longer be seen. So I also want to be able to drap this image around with the cursor. The examples I've found for picturebox zooming cause the picturebox itself to get bigger and smaller. I need it to be like an Access report. Click on the report and it gets bigger. Click again and it goes back to the full image. Does anyone know of an example or tutorial in VB.Net for this type of zoom-with-fixed-size picturebox function?

View 2 Replieshow you can get image transparency to come through in Visual Basic? Because if you try to put an image with some transparent sections on it on a form, the transparency turns into the form background colour (Though you could change the background image to whatever you want displayed under the image, but that's not the point) and basically I can't find any way to do irregular transparencies.
Alright, that's not very simple. I'll try to give an example:
You have an animated GIF of...say...fireworks. And it has a transparent background. Now say you have a few labels with text in them. When you draw the picturebox over the labels, the text in the labels is covered by the background of the fireworks, even though it's transparent. You can't see the labels. You want to see the fireworks exploding over the text
I can't see any way of getting around this, other than doing it in another program and putting the text and fireworks into one PictureBox. but it would be so convenient if it could work in Visual Basic, because you can control the text the in the labels and keep the animated "fireworks" exploding at the same time without using multiple animated images.
Is it possible to have transparency on a form but not on a button on the form?I know transparency can be controlled for the form in properties (VB 2005), but how can we isolate the button from being affected?
View 2 RepliesRight now I currently have an array of pictureboxes, and over them I want another large picturebox that has a sort of transparent fog effect. I created a png with this and made sure to save the alpha transparency, however when the picturebox shows up, you are not able to see underneath it. Is there anyway to fix this without using the GDI instead of pictureboxes? Because of the way the program is set up, I think GDI would be too slow for my purposes.
View 1 RepliesThe 1st problem: I set the transparency key to a color and then set the forms background color to that color, and then set the background image to an image with rounded edges to give my form rounded edged. But the corners look VERY jagged.

Ive been on the same thing for the past seven hours now. Im trying to ether get the MDI child form title-bar-less in maximized mode, or now, get the transparency working to where the MDI child has transparency. ) This is for a home automation system im working on. major alpha stages. Hardware control works ;) but this stupid GUI is kicking my butt. So three options i have. In maximize mode on the MDI child remove the title bar, or remove the parents scroll bar so i can make the MDI child the size of the parents MDI window, or make the MDI child transparency work. Im posting a screen shot to show you what im talking about.

View 4 RepliesI have a 8 bit Gif, that is transparent, with controls sitting on top of it, all in a custom control. This part works fine. However, This control is a menu ring (appears around another control with a few options). The transparent part is over a Picbox, that is in a panel. The transparent part of the image seems to skip the picbox and go right through to the panel. I set the panel to a back color of RED. The custom control when its placed instead of showing the image in the pic box that it is on top of, it shows the RED panel I have made sure all my Z orders are right.

View 1 RepliesI search for a grand total of about four hours online for a method of how to get transparency working in labels in VB.NET 2008. After finding nothing but some example that I have no idea how to implement into my project, I have almost given up. Yes, I've heard about setting the parent properties, but in my case it is imperative that I have labels on top of a PictureBox. (Apparently it's not possible through normal means to have transparent labels over PictureBoxes.)I'm losing my patience with VB.NET, even considering switching back to VB6. How could Microsoft make such a stupid decision? Today I decided to use a stupendous workaround and instead of labels, use transparent PNGs of bitmap text. And guess what? It has the exact same problem as the labels when placed in front of controls! The transparent background has been set to the colour of the form's background!
