I got a situation where i have the first word only of a a child window and the rest of the name changes. I need to find this child window using findwindowex i think by not knowing the full name.
Searching the processes wont work since it is a child.
any other approach on finding next word in a string. What im trying solve is this.
Lets say this is the whole paragraph.

now i search for the word basic.if i press the button find. the first "basic must highlighted, and then if i press again the button the next "basic" is the highlighted one and so on.I already finsih that scenario. What i've done is that first im going to search all the positions of the word and then store it in a array. Then after the array populated with different location of the word that is searching. that is the time i call all the indexes of the array one by one. But i don't want my approach because imagine i have 10000 words. and i search for a word or letter. Lets say the result is 5000 match. so it needs my array to be size in 5000. what a mess in memory.
I don't want to used the FinsString or Find function of VB i want some algorithm to do this. Anyone have a easy approach..
I'm using vb.net to check that certain Excel or Word documents exist in a folder.
EG
strFileFound = Dir("C:TestFolderMyExcelFile.xls")
strFileFound = Dir("C:TestFolderMyWordDoc.doc")
If the documents are created using Excel 97 or Word 97 the files are found. If the the documents are created using Excel 2007 or Word 2007 the files are not found.
I have checked the permissions between the two different versions and they appear to be the same.
why Dir dosen't work with Excel 2007 and Word 2007 files?
I think this capitalizes the first letter in the word "trUe" and makes the rest of the letters lowercase. Like: True
Dim strName
strName = "trUe"
strName = StrConv(strName, vbProperCase)
How would I make it so that if trUe is entered into the RichTextBox1 then it is automatically converted into: "True" ?
txtSubject1Info.SelectionStart = txtSubject1Info.Find("Hey!")
I am finding specific words in the RichTextBox (in this case, "Hey!") and selecting them by getting their initial position through the "Find" command. Unfortunately, this does not work when I have multiple instances of "Hey!" in the RichTextBox. Here's an example:
Text in RichTextBox:
Hey! This is cool!
The Find command would return a value of 0 in this case. However, let's take a look at another scenario:
Text in RichTextBox:
In this case, the Find command would return a value of 0 again, but I want it to get the initial position of the second "Hey!" statement. I'm wondering how I can do this.
I am not an ardent developer in vb.net programming. But off late I am using vb.net to develop a windows application.
The following is what I am trying to do:
I am reading an excel file and storing the string value present in each cell, and trying to match the string in a word file.
The program works fine except that I am having problems in returning the page numbers of the matched string.
The page number value is always returned as one.
The following is a piece of what I had written:
If FindStringInFile(wordfilename, vValues) Then
currentPageNumber = word.ActiveDocument.ActiveWindow.Selection.Range.Information(Microsoft.Office.Interop.Word.WdInformation.wdActiveEndAdjustedPageNumber)
TextBox3.Text = currentPageNumber
End If
wordfilename is my word file and vValues is my excel string data

View 8 RepliesThe following code allows words to be added to a listbox. Add the word to a text file and create a folder with the word as its name. The second part undoes the actions.If I try to delete the word immediately after adding it one of two things happen.
1.An error is reported stating the path cannot be found. Although the listbox index value is correct according to the code the error is pointing at that index +1.
2.The code continues to the point of requesting conformation to delete the folder, still pointing at the index value +1. I the action is confirmed the wrong folder is deleted.
However if I stop debugging, then run the code again all works correctly.Is it likely to persist when the application is compiled?

I have an MDI application where a child form (A) opens a second form as a Dialog (B), which works great but you can't do anything in the MDI until you close the Dialog form.I've now changed the Dialog form (B) so it just calls as a Show and I have disabled the parent form (A). This works better and allows you to click anywhere in the MDI (except the parent form (A)) which is ideal and works much better.
The problem comes if you maximize the parent form (A) and then open form (B), this is then also maximised but I need it to be a fixed.I've done some research and I've tried using the API SetParent which gets round the problem of the form being maximized but this makes the form TopMost in the MDI.
All I need is form B to be topmost of form A and to be a fixed size. Is there any solution?

I have a problem that I�m sure will not be hard to fix for anyone who has been using CR for some time.
To start I have created a program in VB2008 that uses a MS Access data file, I can connect to it with no problem and can also add data and amend data, so all seems to work perfectly. I have published it and it once again runs perfectly on another/s machines.I have now a requirement for a number of reports so have chosen CR for this purpose. I have connected the report to the database and that runs with no problems at all, that is until I try to run it on another machine, it seems not to be able to find the database and comes up with a database Login panel wanting me to log in with a password and Admin name.
I feel it's properly a problem with the path to the database but if I modify the path manually it still won't work.

View 35 RepliesI'm trying to work out a bit of a memory leak and was hoping someone can assist. The below program is running fine except for one thing. 1. The memory leak. When I run the program and watch task manager, I can see the memory usage of the program starts at roughly 14 meg. Over a period of hours, that increases pretty substantially. Eg. at 6am this morning, it was at 14 meg, and by 3pm it was at 36 meg.In a nutshell this program takes an incoming stream of data which looks like this.
MSG,3,51,350,461D3B,1427,2007/02/24,10:58:35.441,2007/02/24,11:03:35.829,,33975,,,53.82440,10.19830,,,0,0,0,0

It basically parses the stream and places items into hash tables depending on the type of data. Eg. I have a hash table for latitude, one for longitude, one for altitude, etc.The key is always the hex code eg. in the first line above the key would be 461D3B.Essentially, as the data arrives in and is parsed and placed into hash tables depending on the type of data, I also have another hash table dedicated to keeping track of timeout times for that individual piece of data. The timer event fires and if the timeout is exceeded for that piece of data then it gets removed from all the hash tables.
I believe this is working. I've done heaps of debug output to the output window ensuring that items are being added to and removed from the hash tables successfully. Eg. ensuring that the hash table record count matches what I believe the number of active records should be.I'm at a loss what could be causing this memory leak though. I'm assuming i'm not disposing of an object properly, or not initializing/declaring it properly, but I can't work out what i'm doing wrong.One thing i'll mention though. The timer event occasionally comes up with a warning about the contents having changed during the For..Next loop. I don't think this will affect things though. As long as the hash table item count matches what it should be, I don't see that being an issue.

Alright, my program requires a folder to put the save files in, and it works fine to create it when I know where the program was installed to. I want to assume that everyone will install to C:/Program Files... however, one cannot assume. Is there a way for me to find out where the program was installed to ie. D:/WorkPrograms/ProgramHere, instead of the Program files? Specifically, is there some sort of code that I can run at startup to find where the program file is, so I can keep all the save files in there?

I have a program I'm working on (a chance game) that has 5 random numbers generated. I need to think of an expression to check to see if three of those numbers are equal.

View 3 RepliesI'm an intermediate student taking on a monopoly game for a summative project. I decided to simulate the game monopoly. The rules are the same as the board game, so the idea is that each "property" or board piece is a button. I will have variables for the players position and player totals. To indicate an owned property, I'll change the buttons to flatstyle and use the bordercolor property.
To indicate the player position, I change the text on the button to include "Player: " etc. The trouble I'm having is that each button is named based on position, followed by the name. ie: "btn1Start", "btn2BalticAvenue", so on and so forth. Now, once I roll the two die and gather random integers, I add the total to the player position. Now what I want to do is find the button that the position corresponds to.
Private Sub turn(ByRef playerPosition As Integer)
Dim die1 As Integer = Int(6 * Rnd() + 1)
Dim die2 As Integer = Int(6 * Rnd() + 1)
playerPosition += die1 + die2
Dim button1 As Button = ?
I've tried various methods. Me.Controls.Contains("btn" & Position) is a boolean, so I can't make an object control class equal to that. Me.Controls.Find requires an exact name, so I can't do Me.Controls.Find("btn" & Position) because it needs the full name - each property has something else added on to the name (eg "BalticAvenue"). I want to set the button equal to the specific button based on the turn position, so I can update the text to include the player and allow him/her to initiate the property's effect (buy/pay rent/or chance cards).
Is it possible in VB .NET to find out if a form is loaded? Also, is it possible to find out if a form is shown at the moment? I think for the second issue it's enough to get the value of the property of the form:
MyForm.Visible
However, I don't know how I could find out if a form is loaded or not.
