View 10 RepliesI am wondering how to have more than one SQL select statement inside my window formapplication that will control the data flow, as i am a newbie in visual basic.net 2005. This is because I am working on a Alarm Application Notifier which will alert the guard on duty as well as inform him the alarm location. The guard's computer screen will be showing the premises and the button will blink at that location where the alarm is. So if the alarm is at block A for example, the guard screen will show block A button blinking.I have already done the first part but i am STUCK at the rest as to how am i going to seperate the conditions for the 3rd to 4th building .The bottom is for the first building code. The data is from the sql database.

So I'm trying out a concept tool of mine where I need to be able to read and write data from a database real easy. I've set up the form as I like and spread around different text boxes and dropdownboxes to read the data from the database. And I've got it all to work and all, but there's a small bug I don't fully understand why's there. Some textboxes don't update the text from the database.
But it seems as it only occurs if the data in the database is nothing. So the value from the last row is still hanging in the textbox and thus, clicking "Update" actually updates the value from the field from the last row, into the new row. Messing everything up.

How can I kill the excel.exe process in SSIS during the data flow task when it fails? There could be multiple instances of Excel.exe running from other packages that are perfectly valid so I don't want to loop through all instances killing them.My problem is that during the data flow task the process will sometimes fail due to a sheet that is named incorrectly or missing columns. This keeps an instance of excel.exe running which is now an orphan task eating up resources so it needs to be killed.At the same time there are other SSIS packages running that are accessing their own excel.exe process and aren't having any issues. So how can I kill the orphan excel.exe process without impacting the other excel.exe process?
View 2 Repliesthat is a question I have been asking myself for a while.Giving a certain flow of events, can I when handling one of them, stop the next ones to be raised? For example, when collapsing a node which child was selected in a treeview (winform), the events are raised like that:[code]I could stop them by using a class member, but I was wondering whether there was a built-in function or just another way (a more elegant way) to achieve this, by acting directly on the events queue.
View 5 RepliesI have been trying to learn how to program a flow chart and am stumped. I want to know how to get the example code from the book that I got at the library to calculate the outcome. I have been at this for days in my spare time and can't figure it out. I tried to apply the examples to my code and got part of it figured out now I am confused on breaking the code down so that I can assign a room if the age is less than 21. Do I just code it the same but change the greater than less than cymbal? I have attached another photo of the code that I have put in Vb for my forum and came up with it between the example in my book and the examples posted on my post. I am getting errors and don't know why.

View 1 RepliesI have a program with three tabs. On tab one I use a folder browser dialogue and load file names into a listbox. These are usually ".tif" image files but could be other image formats. I save the folder location in a variable. On tab 2 I have a Flow Layout Panel. I need to 1) use that folder location on tab 1 as the source of files to be loaded into the flow layout panel and have it do so when I use the Folder Browser Dialogue; 2) I need to click on these tab2 images (in the Flow Layout Panel) to select them, and to trigger events. Mainly create a list of selected image thumbnails.
View 3 RepliesI have been trying to understand how to make thumbnails that I create from a directory, and place in a flow layout panel, selectable. That is, when someone klicks one of the thumbnails that thumbnail should be selected and, either automatically or by the click of a button, a new window (picture viewer) opens and shows the original picture. This is probably very easy to implement, but I am at a loss for the moment.I've tried to find an answer to this by searching the forums, but nothing good has been found so far.
[Code]...
The above code works perfectly and creates thumbnails from the directory c: emp and whatever subdirectory the user writes in the textbox (textbox2). No problem here, it is how to proceed to the next level that has got me stumped. As stated I want the user to be able to select one of the thumnails to get a better look at it in another window. So in selecting it, the procedure should get the path to the original image, and the rest is magic.
im trying to get my from to have a flow panel that shows all open forms and it has to refresh its self when a form open or closes. Ive already kind of done this but im sure theirs a much better way to do it.

Dim formTitles As New Collection

I have a main form having a comobox with categories populated in it. for adding new categories I have a button1 on this main form.

I have checked mainform_activated even but it is not fired on close of form2.

during the development of my project, i'm incurred in the need to use the flow layout panel, but the real need is to show these panels with a defined size without using scrollbars.
I think a kind of dynamic clip of these panels.
For example.
I've a flowlayoutpanel of this visible size (100,200) but its real height is 500, now i've to show to the users the other content of the panel, without using scrollbars.

My code will only let me typ one number into the text box and then it brings me back to the code and says "stack over flow exception was unhandled.
I have a TextBox called Social. As you type in a Social Security Number into the textbox, it formats itself into the standard Social Security Number Format (XXX-XX-XXXX). It automatically adds in the dashes after the third and fifth number, or corrects/removes the dashes if numbers are added or removed from in front of the dashes. Also I coded the script to record the caret's location so that the caret goes back to where the caret was before the adjustment in dashes.
I used Pos and PosHold to hold the caret's location.
The problems I am having are:If I remove a number before one of the dashes, the caret is reset to '0' from using break points, it seem to jump out of the if statement before setting the location of the caret. Sometimes when a number is removed from before the dashes, the dashes are removed like scripted but, the dash is not put back in the correct location. This seems to happen primarily if you have numbers passed the second dash.

I was going through the example code on FTDI's website. After opening the device and setting the flow control to be RTS/CTS they send and receive data in the following manner:
[Code]....
Basically they set the RTS, DTR, then write data to the device. Is this correct? If I was sending multiple times to the device, do I need to clear the RTS each time? and then set it high again? or do I just set it high each time I send new data? Why are they setting DTR if the flow control is defined as RTS/CTS? As far as best practices go, is this the best way to read and write?
I'm developing a program where I've had to add a keyboard shortcuts system. The problem is it uses a third party OCX for a part of its display, and it is catching some essential WM_KEYDOWN messages when in focus, like Ctrl+C, Ctrl+V, etc. I've tried catching the WM_KEYDOWN message through WndProc, but the message is not propagating, so I guess the keyboard messages go from the inner container to the outer one, don't they?
The WM_KEYUP messages can be caught tho, but I'd prefer to be able to catch some of those messages on the KeyDown event. I'm aware I could make some low-level hook, but I'd like to avoid this workaround. Well, if the WM_KEYDOWN message goes from the OCX to its top level container, I guess I'll have to treat those key combinations in the KeyUp event.
Like I imagine everyone, I often have problems navigating my code because the flow can jump from place to place. For example, if my code calls routine1, and I then want to go to routine1's code, I know that I can click in the dropdown menu and it will take me to that sub. But wouldn't it be easier if I could somehow right click on the call to routine way and select something like 'take me there' which would transport me from the function making the call to the code for the function being called? Then it would be easy to hop from place to place.
